OpenTherm Gateway
opentherm_gw
The OpenTherm Gateway integration is used to control the OpenTherm Gateway from 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.
| Entity | Shows up as | Note |
|---|---|---|
switch | Switch or outlet | |
climate | Thermostat | |
binary_sensor | Sensor (motion, contact, leak, smoke…) | |
sensor | Sensor (temperature) | |
button | Button (as a switch) | |
select | Mode picker (as switches) |
What people report
OpenTherm Gateway connects locally over serial or socket. Connection failures usually come from the gateway not responding or HA release regressions.
