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 `

Watch for messages from the envirophat.
