提供了一个用于使用的systemd单元文件。您可能需要在安装之前编辑此文件中的ExecStart行中的设置。将其复制到/etc/systemd/system/，然后运行systemctl daemon-reload。

与homeassistant一起使用

这是我设置的，在我的sensors.yaml文件中

# 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'

我使用以下ExecStart运行envirophat_mqtt

ExecStart=/usr/local/bin/envirophat_mqtt --mqtt_host elgafar.garbled.net --mqtt_topic merope/envirophat --mqtt_clientid merope

确保其正常工作

运行以下命令：mosquitto_sub -v -t "#" -h <your MQTT server>

监视来自envirophat的消息。
