A systemd unit file is provided for use. You may want to edit the settings in the ExecStart line of this file before installing. Copy to /etc/systemd/system/ and then run systemctl daemon-reload.
Use with homeassistant
This is my setup, in my sensors.yaml file:
# garage envirophat
- platform: mqtt
name: garage_temperature
state_topic: merope/envirophat/temperature
unit_of_measurement: '°C'
- platform: mqtt
name: garage_pressure
state_topic: merope/envirophat/pressure
unit_of_measurement: 'hPa'
- platform: mqtt
name: garage_lux
state_topic: merope/envirophat/lux
unix_of_measurement: 'lux'
I run envirophat_mqtt with the following ExecStart:
ExecStart=/usr/local/bin/envirophat_mqtt --mqtt_host elgafar.garbled.net --mqtt_topic merope/envirophat --mqtt_clientid merope
Making sure it works
Run the following command:
mosquitto_sub -v -t "#" -h <your MQTT server>
Watch for messages from the envirophat.
