iGrill

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

What do you need

Hardware

• An iGrill Device (and at least one probe) - iGrill mini, iGrill 2 or iGrill 3
• 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. Add at least one device config (see ./exampleconfig/device.yaml) - to find your device MAC just run hcitool lescan: change a few hard-coded items (e.g. the MAC address of the iGrill 2 device)
4. start application ./monitor.py
5. enjoy

systemd startup-script

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

Troubleshooting

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"
