Built inCloud polling

The Compit integration allows you to integrate air conditioning, ventilation, and heating controllers with Home Assistant. You need a Compit iNext account, which you can set up at inext.compit.pl.

Documentation Source code

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
`fan`	Fan
`binary_sensor`	Sensor (contact)
`sensor`	Sensor (CO₂, PM10, PM2.5, humidity, temperature)
`water_heater`	Water heater (as a thermostat)
`select`	Mode picker (as switches)

What people report
