EARN-E P1 Meter
earn_e_p1
The EARN-E P1 Meter integration connects to the EARN-E energy monitor, a device that reads your smart meter's P1 port and broadcasts real-time energy data via UDP on the local network. This integration listens for those broadcasts and exposes them as sensor entities.
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.
