Monitor a Pi Zero with and Enviro+ board in Home Assistant

Enviro+ Monitor for Home Assistant

This python script that runs every 60 seconds and sends several system data over MQTT. It uses the MQTT Discovery for Home Assistant so you don’t need to configure anything in Home Assistant if you have discovery enabled for MQTT

It currently logs the following data:

• BME280 Temperature
• BME280 Humidity
• CPU usage
• CPU temperature
• Disk usage
• Memory usage
• Power status of the RPI
• Last boot

Installation:

1. Enable I2C and SPI
2. pip3 install -r requirements.txt --user
3. sudo cp ~/ha-enviroplus/enviroplus-monitor.service /etc/systemd/system
4. sudo systemctl enable enviroplus-monitor.service
5. sudo systemctl start system_sensor.service
