MiTemperature2 / Home Assistant / MQTT

README.md

Building

docker build . -t jakzal/mitemp2

Running

Manually

docker run -it --rm --net=host \
    -e MITEMP_DEVICE=AA:C1:38:E7:22:11 \
    -e MITEMP_DEVICE_NAME=guest-room \
    -e MQTT_HOST=localhost \
    -e MQTT_USERNAME=homeassistant \
    -e MQTT_PASSWORD='pa££w0rd' \
    jakzal/mitemp2

or:

docker run -it --rm --net=host \
    -e MQTT_HOST=localhost \
    -e MQTT_USERNAME=homeassistant \
    -e MQTT_PASSWORD='pa££w0rd' \
    jakzal/mitemp2 \
    python LYWSD03MMC.py -d AA:C1:38:E7:22:11 --name guest-room -r -b 100 --skipidentical 50 -deb

Systemd

Create configuration files:

• /usr/share/hassio/homeassistant/.storage/mitemp2/common
• /usr/share/hassio/homeassistant/.storage/mitemp2/office
• /usr/share/hassio/homeassistant/.storage/mitemp2/toilet

Services

Enable services:

systemctl enable mitemp2@office.service
systemctl enable mitemp2@toilet.service

Start services:

systemctl start mitemp2@office.service
systemctl start mitemp2@toilet.service

If you prefer to use timers, enable *.target units instead of *.service (i.e. mitemp2@office.target instead of mitemp2@office.service).
