Sofar
sofar
The Sofar integration connects Home Assistant to a Sofar Solar inverter over Modbus TCP, either directly to an inverter with a network port, or through a Modbus TCP bridge for inverters that only expose RS485.
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.
| Entity | Shows up as | Note |
|---|---|---|
switch | Switch or outlet | |
binary_sensor | Sensor (motion, contact, leak, smoke…) | |
sensor | Sensor (temperature) | |
button | Button (as a switch) | |
select | Mode picker (as switches) |
What people report
Sofar inverters are polled over Modbus TCP only.
