Hacking the iGrill (mini, V2 & V3)

iGrill

Monitor your iGrill (mini, v2 or v3) (with a Raspberry Pi 1/2/3) - and an forward it to an mqtt-server

Tested with Docker on a Pi 3 and Pi Zero W with iGrill v3.

What do you need

Hardware

• An iGrill Device (and at least one probe)
  • iGrill mini
  • iGrill v2
  • igrill v3
• A bluetooth enabled computer - preferable a raspberry pi
• A mqtt server as message receiver

Installation

1. clone this repo
2. install required modules (see requirements.txt)
3. create a config directory and add at least one device config (see ./exampleconfig/device.yaml). To find your device MAC just run hcitool lescan
4. start application, any of:
   • Run in docker (recommended): docker-compose up -d
   • Run manually: ./monitor.py -c <config_location>
   • Set up systemd service (see below)

systemd startup-script

Place this file into the proper folder - for instance: /lib/systemd/system/igrill.service

[Unit]
Description=igrill MQTT service
After=network.target

[Service]
Type=simple
Restart=always
RestartSec=2
ExecStart=/usr/bin/python <path_to_igrill_repo>/monitor.py -c <path_to_config_dir>

[Install]
WantedBy=multi-user.target

Run systemctl daemon-reload && systemctl enable igrill && systemctl start igrill

Next time you reboot, the iGrill service will connect and reconnect if something goes wrong...

Troubleshooting

View the docker container logs with docker-compose logs.

If your device is stuck on "Authenticating" the following has been reported to work:

1. within the file /etc/bluetooth/main.conf under [Policy] check the existence of AutoEnable=true
2. Comment out below line in /lib/udev/rules.d/90-pi-bluetooth.rules by prefixing "#" the line ACTION=="add", SUBSYSTEM=="bluetooth", KERNEL=="hci[0-9]*", RUN+="/bin/hciconfig %k up"
