Pi Recipes

Initial play with private AI gizmo ... ultimately hope to build something creepy like this  https://homespace.is/ai

*** Feb 2023 - Ack!  one step forward, one step back ... I knew Picroft was precarious (Nov 2022 was last of it) but there are some troubles upstream with Mycroft - here's the note from the CEO - https://community.mycroft.ai/t/update-from-the-ceo-part-1/13268.  I will monitor and also follow antics of https://openvoiceos.com/

In the meantime .... Taking a look at Rhassby via https://rhasspy.readthedocs.io/.  Sing-a-long @ https://rhasspy.readthedocs.io/en/latest/tutorials/#from-scratch-on-a-raspberry-pi

1. Raspberry Pi imager -> 32-bit RaspOS Lite to 16g SD

2. Per instructions:  Created ssh directory in boot partition and added a known-good wpa_supplicant.conf so I could bootup and ssh in (I didn't know this!  Handy!) ... BUT THAT DIDN'T work ... it looks like the new RaspOS requires a user setup (pi is no longer default).  Oh well, boot with monitor&keyboard and enable ssh and season to taste! (as always_ 

3. via ssh:

   • Install Docker via - curl -sSL https://get.docker.com | sh

   • Add pi to docker group - sudo usermod -aG docker pi

   • <reboooootaaaarooooo> - sudo reboot

   • ssh back in and (sit tight, this will take time) .... docker pull rhasspy/rhasspy 

   • Then - fire it up via  -
     docker run -it \
     -p 12101:12101 \
     -v "$HOME/.config/rhasspy/profiles:/profiles" \
     -v "/etc/localtime:/etc/localtime:ro" \
     --device /dev/snd:/dev/snd \
     rhasspy/rhasspy \
     --user-profiles /profiles \
     --profile ensudo reboot

   • Browser in via http://<IP_ADDRESS>:12101

   • To live through reboot use:
     docker run -d \
     -p 12101:12101 \
     --name rhasspy \
     --restart unless-stopped \
     -v "$HOME/.config/rhasspy/profiles:/profiles" \
     -v "/etc/localtime:/etc/localtime:ro" \
     --device /dev/snd:/dev/snd \
     rhasspy/rhasspy \
     --user-profiles /profiles \
     --profile en

4. Then into getting started guide @ https://rhasspy.readthedocs.io/en/latest/tutorials/#getting-started-guide

--------- Earlier ....

We'll start with https://mycroft.ai/ - Baby steps!

Easiest start is via https://mycroft-ai.gitbook.io/docs/using-mycroft-ai/get-mycroft/picroft.  Came right up on RPI3B+ and ran even better on RPI4.   Started with monitor, keyboard/mouse and HDMI sound.  Good way to get to know mycroft and related components.

*** Jan 21 2023 - back to picroft image ...

• Fixed on major roadblock to my headless hardware set up ... could not get audio to come out of standard 3.5mm headphone jack
  using raspi-config or mycroft-setup-wizard.  Finally brute force fix it via these steps:

  1. Check list of audio playback hardware using aplay command - it looks like this:
     $ aplay -l
     **** List of PLAYBACK Hardware Devices ****
     card 0: b1 [bcm2835 HDMI 1], device 0: bcm2835 HDMI 1 [bcm2835 HDMI 1]
     Subdevices: 4/4 Subdevice #0: subdevice #0
     Subdevice #1: subdevice #1
     Subdevice #2: subdevice #2
     Subdevice #3: subdevice #3
     card 1: Headphones [bcm2835 Headphones], device 0: bcm2835 Headphones [bcm2835 Headphones]
     Subdevices: 4/4
     Subdevice #0: subdevice #0
     Subdevice #1: subdevice #1
     Subdevice #2: subdevice #2
     Subdevice #3: subdevice #3

  2. Edit /etc/mycroft/mycroft.conf to set correct card number (hw:1 is headphone jack) ... first 2 lines in my .conf
       "play_wav_cmdline": "aplay -Dhw:1,0 %1",
     "play_mp3_cmdline": "mpg123 -a hw:1,0 %1",

• Set rpi activity let to 'heartbeat' rather than sd activity ... more appropriate for a headless gizmo like this!
  Edit good old /boot/config.txt using stuff found in /boot/overlays/README (heartbeat is also a load indicator, we'll know if picroft is working harder)
  # Tped was here trying to turn  RPI act led into heartbeat rather than
  dtparam=act_led_trigger=heartbeat

• Start to make it me!

----------------------------------------------

**** Dietpi abort (hopefully just a pause) struggling with permissions (I think when I try to run mycroft utilities - like skill maker (mycroft-msk) .... ****

I moved on to fav foundation - dietpi.  doc/quickstart @ https://dietpi.com/docs/.  Mycroft is part of optimized software library *and* seems to run better than the picroft image, see https://dietpi.com/docs/software/hardware_projects/#mycroft-ai.    

This one looks like a keeper! ...  I'll cleanup the recipe below and probably call ours  "ServerPi".   It is now basically a local utility server with a nice face (UI) .... I think there will be a number of handy Self-Hosted apps to come.

------

Project history (in nutshell):  Started looking into monitoring our ISP internet speeds and stumbled upon https://github.com/geerlingguy/internet-pi with thoughts of cramming it into SentinelPi.  Had many struggles attempting to get Internet-pi in/up/running and ended up building a utility server that combines a number of handy local network services and links (instead of Browser bookmarks).  The server was initially built using DietPi, Pi-Hole, Speedtest Tracker, docker (portainer) and a friendly web face (homer).  This server will be foundation for our self-hosted apps - including Internet Speedtest-tracker to monitor our ISP (much easier).    

Initially just replaced/documented our NetAidPi.  It was an old rpi (Model B!)  that has been running on the network for quite a long time  (PiHole, Murmer and some other services that I didn't even remember!   Simply notes for now ....

From the beginning .... hopefully final

1. dietpi, downloaded https://dietpi.com/downloads/images/DietPi_RPi-ARMv8-Bullseye.7z 

2. rpi imager ... just a couple of mins

3. Boot on the target network and config via ssh (pi-hole needs static IP)

4. Dietpi setup (approx 10)

   • Change passwords

   • Disable serial/UART

   • Dietpi-config

     1. Display->GPU Memory Split to 16 (server)

     2. Language/Local->Season to taste (timezone)

     3. Security->Set Hostname

     4. Network Adapters->Wifi off, Ethernet set to Static (for Pi-Hole's sake) ... will need to re-ssh after this one is applied

     5.  <fumble thru reconnect & reboot here>

5. Dietpi Software

   • 2    Folding@Home: distributed disease research project.  Interface @ http://<NetAidPi>:7396/

   • 17   Git: Clone and manage Git repositories locally

   • 34   PHP Composer: Package manager for PHP

   • 84   Lighttpd: Extremely lightweight webserver

   • 87   SQLite: Persistent single-file database system

   • 89   PHP: Hypertext Preprocessor for dynamic web content

   • 93   Pi-hole: block adverts for any device on your network.  Interface @ http://<NetAidPi>/admin
     // Don't forget to record admin PW during install  or you will need to do one of these:  pihole -a -p //

   • 94   ProFTPD: Efficient, lightweight FTP server

   • 103  DietPi-RAMlog: Makes /var/log a RAM disk, preserves file structure on reboot

   • 104  Dropbear: Lightweight SSH server

   • 130  Python 3: Runtime system, pip package installer and development headers

   • 162  Docker: Build, ship, and run distributed applications

   • 185  Portainer: Simplifies container management in Docker (standalone host).  Interface @ http://<NetAidPi>:9002
     // Set password when you first fire it up via browser - do it soon after install or it times out and needs to be restarted 

   • 200  DietPi-Dashboard: Official lightweight DietPi web interface.  Interface @ http://<NetAidPi>:5252
     // Config @ /opt/dietpi-dashboard/config.toml

   • 205  Homer:  Homer is a modern and lightweight dashboard & homepage for your services. Interface @  http://<NetAidPi>/homer

6. Non Dietpi software

   • My buddy joe, the editor:   apt-get install joe

   • Speedtest-tracker installed via portainer - doc @ https://docs.speedtest-tracker.dev/

     1. Clink on  local Environment (set up above) - click around until you add a Stack

     2. In create Stack dialog:

        •  name=speedtest-tracker (must be lower case)

        • Web Editor, paste in Docker Compose (sqlite) snippet from https://docs.speedtest-tracker.dev/getting-started/installation

        • Clink on Deploy Stack

     3. Interface @ http://<NetAidPi>:8080/ - default uc/pw= admin@eample.com/password

        • Settings:   Set timezone

        • Authentication currently required even though there is a toggle.  update periodically to see new features

7. <Test everything here>

8. Pull it all into homer screens

   • icons (I made 64x64 png) are stored in /var/www/home/assets/icons 

   • homer as doc root in lighttpd.conf - DONT DO THIS!  Then EVERYTHING must be under homer!

   • server.dir-listing = "enable" OR  dir-listing.activate = "enable"

---------------

Notes from Attempt #4 - Looks like a keeper.  Decided that NetAidPi will remain standalone, I forgot that SentinelPi sits on a mirrored Ethernet port, it sees all IoT traffic, NetAidPi doesn't need all that.  Also upgraded to RPI4 for ISP monitoring (RPI3B+ ethernet seemed to max out ~150M) and for folding@home.

• Homer is nice - pulling together all home hardware/servers/apps that have web interfaces. 
  See https://github.com/bastienwirtz/homer/blob/main/README.md

  • Learning about FontAwsome @ https://www.webdevsplanet.com/post/font-awesome-icon-style-classes

  • It also has some <can't remember what I was going to type here ... fun!>

• Had to install php for Pi-Hole ...I was getting "503 Service Unavailable" when accessing Admin console.  Dietpi software is missing something (either with Lighttpd or Pi-Hole)

• I'll cut an image of NetAidPi at this point ... it works!   "Internet-pi" made a mess in here last time

• Uninstalled unbound dns *and* pi-hole because pi-hole was coughing up errors instead of statistics on its dashboard - "unknown error while loading data".  Seems better

• Will try https://docs.speedtest-tracker.dev/ this time around ... docker via portainer

  • Aiming at this UI (I use grafana on sentinelpi)  https://grafana.com/grafana/dashboards/17460-speedtest-tracker-v2/

  • installed docker, docker-composer, portainer and sqlight, lighttpd from dietpi software  

----------

Attempt #3!    ACK ACK ACK - Enough with https://github.com/geerlingguy/internet-pi!  Way too complicated for the problem at hand ... I just need a speedtest script/datastore, a dashboard *AND* I want to see how it all goes together!!!!!   RaspOs, intrnet-pi (and friends) was blowing up all over the place - I was chasing missing packages, path issues and my usual config fumblings (due to briefly scanning instructions!)

------------------------
Attempt #2 - ACK ACK!  This was a bust too!  All sorts of fumbling installing ansible (missing rust complier ... followed by comedy of errors)

----------------
Attempt #1 - ACK!  This was a bust!  Internet-pi seems to be dependent on stock raspos (maybe pi user? I'll revisit at some point)

This one is turned into SentinelPi - original notes/fumbling/flailing moved over there

Jan 2023:  FINALLY Back at it!  Ran GCompris on stock RPIOS for the heck of it and it ran MUCH better than on DietPi ... not sure why, but it's running great on an RPI3 and looks like it will live in harmony with CutiePi world if need be .. .

Final notes/recipe @  SmartiePi - First Computer for 4-6 Year Old

Feb 2022:  Moved to this site.  Cut/Paste from 'Classic' Google site page @ http://ventures.tpedersen.net/errata/raspberrypi/smartiepi ... did not paste in very well!  

I often make Pi's for others - pre-configuring them for WiFi in someone else's home is a pain in the drain!

Gave Comitup a quick once over - there was a downloadable image @  https://davesteele.github.io/comitup/.    It looks to be JUST what I need AND it WORKS!

Posted experiences with the downloadable image (RaspOS that boots up with Comitup) in Raspberry Pi OS Alternatives.  

I am currently exploring installing/incorporating  Comitup packages into my projects as opposed to starting with the image because I use a variety of OS underpinnings - Q4OS, DietPi, Manjaro ...  it (comitup-1.15-1) seems to be in latest RaspOS which should allow me to apt-get install on everything except Manjaro.  I don't see it in Manjaro or Arch AUR

1. Dietpi+Comitup:  

   • Downloaded Dietpi ARMv6 32-bit. Uses the Raspbian package repository which provides comitup for install!

   • Booted on RPi4 to start with ... usual blow-by-blow

     • Auto updates itself & reboots - now at v8.3.1 - ~5min

     • Forced PW changes, disabled serial console

     • Dietpi config/software

       • Audio:   Enabled, Sound card usb-dac (I'm going to mess with CutiePi enhancements first)

       • Language/Regional:  Locale en_US.UTF8, Timezone & us keyboard

       • Security:  Set Hostname

       • Network/Adapters:  Enable Wifi

       • Network/Other:  Turned Off Boot wait for network (just to be safe)

       • Dietpi Software (season to taste:  I installed stuff I want to live/play together):  Shairport, Murmur, Raspotify, RPI.GPIO, python3, go, ALSA, GIT

     • Stuff I had to install by hand ... via ssh 

       • My editor:  good old joe - apt-get install joe

       • comitup from https://davesteele.github.io/comitup/ - apt-get install comitup
         // Whoops!  WiFi was disabled by default in Dietpi, comitup choked during install - Make sure you add Network steps in dietpi-config above //

       • Whoops AGAIN!  I forgot to RTFM @ https://github.com/davesteele/comitup/wiki/Installing-Comitup ... and I quote:

         • Allow NetworkManager to manage the wifi interfaces by removing references to them from /etc/network/interfaces.

         • Rename or delete /etc/wpa_supplicant/wpa_supplicant.conf.

         • The systemd.resolved service should be disabled and masked to avoid contention for providing DNS service.

         • The line dns=dnsmasq should not be in /etc/NetworkManager/NetworkManager.conf.

         • also changed default ssid in /etc/comitup/comitup.conf - now ap_name: <hostname>-<nnn>

       • I also added comitup to dietpi-services (right or wrong?)

       • comitup-cli is a useful command line tool here

   • Hey!  It works!
     
     

2. Q4OS+Comitup 

   • <next in queue ... I'd think it would work, raspos-based>

Playing w/ OpenCanary Honeypot ... this is a mess/work-in-process

Sing-a-long w/ https://github.com/thinkst/opencanary#readme but ....
.... watching this one as I do:  https://simpaul.com/opencanary-on-a-pi-quick-setup/

Step by step (notes to self)

RPIOS - lite is fine, usual setup:  update/upgrade, rpi-config: pw, hn, local/kb, yada/yada

Switch to Ubuntu 20.04 LTS 32-Bit for 3 reasons - NOPE!  That came out badly

From guide ....

1. OS Tweaks:  Set interesting Mac Address (per Paul's guide) ... add "smsc95xx.macaddr=<enticing mac>" to cmdline.txt

2. Python Prep is a combo Open Canary Guide & Paul's (Including samba and scapy/pcapy because I want it all!)
   sudo apt-get install python3-dev python3-pip python3-virtualenv python3-venv python3-scapy libssl-dev libpcap-dev
   sudo apt install samba # if you plan to use the smb module

3. Back to Paul's guide - looks like he skipped virtual env this go round ... sounds simpler

pip3 install --upgrade setuptools
git clone https://github.com/thinkst/opencanary
cd opencanary
sudo apt-get install libffi-dev # Paul may have missed this one, fatal err missing
sudo python3 setup.py install

4. Set up a couple of links ... from Paul's guide but check version of scripts directory in copy below ... his were 3.7, mine are 3.9
   sudo link /usr/local/bin/twistd /home/pi/opencanary/bin/twistd
   sudo cp ./build/scripts-3.9/opencanary.tac /usr/local/bin/opencanary.tac

5. Back to Opencanary guide for this part ... it did generate config file for me
   $opencanaryd --copyconfig
   [*] A sample config file is ready /etc/opencanaryd/opencanary.conf
   [*] Edit your configuration, then launch with "opencanaryd --start"

6. Edit /etc/opencanaryd/opencanary.conf ... I just poked around initially - Banners 

7. Fire it up ... see if it runs foreground
   opencanaryd --dev

8. Couple of warnings to cleanup from initial run ...

<clip>
UserWarning: You do not have a working installation of the service_identity module: 'No module named 'service_identity''. 
Please install it from <https://pypi.python.org/pypi/service_identity> and make sure all of its dependencies

are satisfied.  Without the service_identity module, Twisted can perform only rudimentary TLS client hostname verifica

tion.  Many valid certificate/hostname mappings may be rejected.

I'm a good guesser ... closed my eyes and fixed this via ...
pip3 install service_identity

9. Turn it into a service so it starts on boot (thx again, Paul)
   File /etc/systemd/system/opencanary.service created, it now contains:

[Unit]
Description=OpenCanary honeypot

After=syslog.target

After=network.target

[Service]

User=root

Restart=always

WorkingDirectory=/home/pi/opencanary

ExecStart=/home/pi/opencanary/bin/opencanaryd --dev

[Install]

WantedBy=multi-user.target

10. Fire it up ...
    sudo chmod 644 /etc/systemd/system/opencanary.service
    sudo systemctl enable opencanary.service
    sudo systemctl start opencanary.service
    sudo systemctl status opencanary.service

11. Boot ... to see what happens

enough for now ...

-----------------

Leftovers to deal with
pip install scapy pcapy # optional

Whoops!  that failed
No package 'libffi' found

• DietPi software - https://dietpi.com/docs/software/media/#murmur

• Murmer Server config @ /etc/mumble-server.ini

Also:  Dietpi possibilities for V4

• Samba instead of FTPing - https://dietpi.com/docs/software/file_servers/#samba

• Raspotify?  Playlist rather than uploaded songs/sounds?

• Lighttpd for configing and such - https://dietpi.com/docs/software/webserver_stack/#lighttpd

Bottomline:  This MAY work if I need it ... more putzing to do to get it installed and not as full featured as rpi default vnc server (realvnc).

Considerations/ToDo's
- XP lookswitcher (XPQ4 Desktop) does not show in remote session (I'm probably NOT in the session I'd like to be)
- Below includes definitions for systemd service but I think I'd just fire this up via CLI on an as needed basis
- I still need to double check that it works via remote.it (remote control gizmo I use)

-------

Motivation:  Struggling with stock (RealVNC) vncserver on latest GramPi rebuid ... thought I'd try TightVNC for the heck of it

Rough notes as I go ... Working with Q4OS, but I'd guess this will work on RaspiOS too

TightVNC looks to be GPL, actively maintained and has been around for a long time (> 10 years).  

Most doc seems to be focused on windoze, but this guy posted a RPi step-by-step 

Notes as I go in case I need to retrace my steps

1. Turned off stock VNC Server via sudo raspi-config -> Interface Options -> Disable VNC

2.  Install via sudo apt-get install tightvncserver (this did remove package realvnc-vnc-server)

3. Initial run of vncserver to setup passwords ... it went a little like this ...
   
   vncserver
   
   You will require a password to access your desktops.
   Password: 
   Verify:   
   Would you like to enter a view-only password (y/n)? n
   New 'X' desktop is GramPiV2:1
   Creating default startup script /home/pi/.vnc/xstartup
   Starting applications specified in /home/pi/.vnc/xstartup
   Log file is /home/pi/.vnc/GramPiV2:1.log
   
   

4. Create service per devdude's example, it looks like this:
   cat /etc/systemd/system/vncserver.service

[Unit]
Description=TightVNC Server
After=network.target

[Service]
Type=forking
User=pi
ExecStart=/usr/bin/vncserver :1
ExecStop=/usr/bin/vncserver -kill :1

[Install]
WantedBy=multi-user.target

5. Enable the service to get links built and such ... like this

sudo systemctl enable vncserver

systemctl status vncserver

● vncserver.service - TightVNC Server

  Loaded: loaded (/etc/systemd/system/vncserver.service; disabled; vendor preset: enabled)

  Active: inactive (dead)

6. Tested via screen sharing on macbook and tigervnc viewer on linux ... seems to work
   some notes ...
   - port is 5901
   - not as full featured as realvnc

Moved to tech.tpedersen.net Feb 2022.  Cut'n Paste from 'Classic' Google site page @ http://ventures.tpedersen.net/errata/raspberrypi/occupi ... VERY STRANGE, this page pasted into new sites quite well, PanelPi was a total mess!

OccuPi - Remote Controlled Full Screen Kiosk-Like thingy

Last update:  09 October 2020

Original 15 September 2020

VERY EARLY Stages, this page will be a mess as I stumble thru this ...

The Goal is to build a little Pi that will connect to my parents TV to allow me to share (project) videos, web pages and such.  Will be used during COVID-19 to keep them occupied over the winter months.  More to come as this idea develops.

Notes/Updates

09 Oct:  Struggling to find OS fast enough to use Google Streetview in Full Screen or Kiosk mode on a Raspberry Pi 3.  It appears that I MUST run Chromium browser to pull this off.  Have tried Arch, Dietpi and Raspbian lite.  On to Chromium OS.  Also created subordinate startpage to simplify testing ... we may end up with a simple webpage providing links to all activities,  

25 Sept:  General concept works very well, even had an old gyration remote control working with it.  RaspOS was painfully slow on the RPi3.  Switching to LXDE desktop from Dietpi to see how that runs.  Dietpi has been my goto for servers, really haven't played with desktop. 

Dietpi/Chromium kiosk is pretty slow.  Friggin streetview map is upside down too!  Added a startpage to facilitate adding activities/features without connecting to or messing with OccuPi system

Dietpi Setup Notes

• Diepi-config ... minimal work here, let software packages tweak as needed

  • Language/Regional:  en_US.UTF-8, set TZ and US Keyboard

  • Security:  Set Hostname

  • Autostart:  Try Chromium under browser kiosk! - NOT YET!

• dietpi-software

  • [X} Chromium: web browser for desktop or autostart

  • [X] RealVNC Server: desktop for remote connection  

  • [X] Remot3.it: (Weaved) access your device over the internet

  • REMEMBER to select START INSTALLATION!

• NOW back to diet-pi-config

  • Autostart: Chromium under browser kiosk!

  • 
    

----------- RaspOS aborted for now - Save in case I fallback -----------

Steps (raspos)

• Etcher 

• New RaspOS (or whatever) resizes & does a GUI setup on first boot

  • Set Language, Timezone and keyboard

  • Forces user pi password change

  • Screen Setup - gets rid of boarder

  • WiFi Connect (if needed)

  • Software Update - But .... "Error Comparing Versions" - Nice try!

  • <Attempted reboot ... but I wasnt read!>

  • Via Terminal - sudo raspi-config

    • Boot Options

      • Desktop w/ Autologin Pi

      • Wait for Network

      • Graphical Splash Screen

    • Interfacing Options

      • SSH Enable (for remote me!)

      • VNC Enabled (for remote me!)

  • Couple of Installs

    • Joe - my editor of choice -> sudo apt-get install joe

    • remote.it - Remote Control software (nice)  

      • sudo apt-get install remoteit (to install)

      • http://occupi.local:29999 (to config - sooo nice!)

  • Now Attempt Full Screen Browser ...
    from https://blog.gordonturner.com/2020/06/30/raspberry-pi-full-screen-browser-2020-05-27-raspios-buster/

    • Finally learning to follow directions!
      
      

    • sudo apt-get update -y 

    • sudo apt-get upgrade -y
      sudo apt-get dist-upgrade -y
      sudo apt-get autoremove -y

    • Install Dependencies
      
      

    • sudo apt-get install -y ttf-mscorefonts-installer unclutter x11-xserver-utils

    • 
      According to guide:
      ttf-mscorefonts-installer adds common web fonts
      unclutter is used to hide the mouse cursor
      x11-xserver-utils installs xset, which is used to disable screen blanking
      
      

Last Update - 21 July 2020

Here wee go again!  PanelPi - A little Pi help to integrate old wired alarm system

*** VERY early in the project, this page is expected to be a mess for quite a while (as usual) ***

Background

PanelPi was initially cobbled together to explore sprucing up our wired home security system.  Current plan is to integrate a number of hardwired sensors into our 'Smart' home.  We'll see!

Software 

• Dietpi.com - My Favorite!  Download latest RPI version (Donate!)

• Etcher.io - Much easier way to flash OS images to SD 

• Couple of Software installs from DietPi's Optimised Software Collection

  • OpenSSH instead of Dropbear SSH Server.  Supports SCP xfers

  • RPi-Monitor - Web interface system stats

  • RPi.GPIO - gpio interface library for rpi (python) 

  • WebIOPi - web interface to control rpi.gpio  

• WebIOPi - web interface to control GPIO.  Install by hand dietpi install fails

Hardware

Current Config

• Raspberry Pi 1 Model B.  Arm6 w/ Ethernet + two USB ports

• EDIMAX USB WiFi adapter

• Old/Original RPi Power Supply (1 amp!)

• Really Old 8g Micro USB card

• Multimeter, some hook clip test thingies (from my Burroughs days!!!)

Stuff to Explore

• Shelly.cloud - Smart relays, switches, sensors

• EnvisaLink EVL-4EZR For DSC & Honeywell Systems

• Konnected.io - Designed to smarten old wired alarms/sensors 

• https://reolink.com/use-upgrade-existing-home-security-alarm-system/ 

• https://www.instructables.com/id/Ethernet-Enabled-DSC-Home-Security-System/

Step by Step (rough notes to self, I'll cleanup later)

Phase I - Pi in Panel. 

Get Panel online - currently in Wifi deadspot.  Use Webiopi to see what is going on with existing sensors.   

• Dietpi via etcher

  • dietpi-config  - as usual - security, naming, etc

  • dietpi-software:  Openssh + RPI-Monitor, RPi.GPIO from optimized software list

  • Don't forget my  editor - apt-get install joe

• Webiopi via instructions @ http://webiopi.trouch.com/INSTALL.html

  • Easiest to download via gui on main system and scp to PanelPi.  Syntax: 

  • scp WebIOPi-0.7.1.tar.gz root@panelpi:/home/WebIOPi-0.7.1.tar.gz

  • Via SSH:

    • Install (setup.sh took a looong time on RPi 1!) 

    • $ tar xvzf WebIOPi-x.y.z.tar.gz

    • $ cd WebIOPi-x.y.z
      $ ./setup.sh

    • Fire it up to test 

    • webiopi -d -c /etc/webiopi/config

  • Access via http://panelpi:8000 

    • Default user/pw "webiopi"/"raspberry".  

    • Change pw using  webiopi-passwd

    • Check /etc/webiopi/config

  • Run a daemon
    
    

  • /etc/init.d/webiopi start/stop

  • Start at boot
    
    

  • update-rc.d webiopi defaults

  • <reboot> to get the witches out and to make sure it all comes up OK before disconnecting keyboard & monitorand moving to the panel!

• Cleanup

  • RPi Monitor data.conf (no ethernet):  Comment out network.conf, uncomment wlan.conf 

  • Disable wifi powersave mode (iwconfig wlan0 power off DID NOT WORK)
    
    iw dev wlan0 set power_save off

  • Reboot with old PS, just to make sure it works!

• Hardware Contraption

  • <coming soon>
    
    

Notes

- PanelPi will have to Wifi to SuitiePi - forgot to run Ethernet to panel area when I had wall out!!! Argh!

    - remember to static route and reserve dhcp so I can find/access PanelPi on that subnet

- WebIOPI did not install via Dietpi ... attempting by hand

    - RPi 1 Model B -> Install instructions @ http://webiopi.trouch.com/INSTALL.html

    - RPi 2 and beyond (40pin GPIO) @ https://thepiguy.altervista.org/webiopi-rp3/

Log, Odd and Ends and fond memories

July 2020 - rebuild

• Can't recall details but had to rebuild,  Dietpi Buster

• Decided to switch to RPI 1 Model B - good use for it

  • 26-pin GPIO is fine. 

• FINALLY traced my steps .... current recipe above

June 2020 - Back at it

• Had to turn on WiFi reconnect in dietpi-config.  I wonder if wifi is dowzing off, powersave?

downloaded attached a GPIO pinout leaf - We'll see if it helps, pretty small print for old eyes!

- Ghazooks!  To keep all this stuff going on our network remember the following.

1. Add host to local DNS in protected router

2. DHCP reservation in AP (SuitiePi), remember to change when hardware is swapped

3. Static Route to PanelPi in ISP router
