SAJ Solar Inverter
saj
The SAJ Solar Inverter integration polls a SAJ solar inverter through its local web interface and presents the values as sensors in Home Assistant.
In Apple Home through HomeKit Bridge
What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.
