solarman-mqtt

Poll Solarman APIs and display data in HomeKit via MQTT broker

Features

• Display battery power as a light sensor
• Display "Inverter Supply" as a contact sensor (useful for checking if supply is from Inverter or Grid)
• Display battery SOC as a meta property on the contact sensor
• Display low battery alert below a configured threshold
• Display if battery is charging

Screenshots

Disclaimer

• This has only been tested on a Sunsynk inverter with a Solarman WiFi data logger.
• The docker images only targets the linx/arm/v7 architecture (raspberry pi 3b)

Prerequisites

• docker
• docker-compose
• homebridge
• homebridge-mqtt plugin

Limitations

• The Solarman WiFi loggers only send data every 15 minutes or so (the POLL_INTERVAL should be set accordingly)
• Power values (usually watts) are modelled as a light sensor in HomeKit (in Lux). HomeKit does not support any sensor capable of displaying watts.

Setup

See the example docker-compose.yml for details.
