Home Assistant custom component for monitoring and controlling Coway Airmega Purifiers
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 | |
fan | Fan | |
sensor | Sensor (temperature, humidity, air quality…) | |
select | Mode picker (as switches) |
What people report
Coway Airmega purifiers work via the IoCare cloud; unregistered filter data on 250S and MightyS caused a setup error that was later fixed.

| Coway Airmega 250S | Works Cloud | Listed; EU variant detection fixed; pre-filter error resolvedSaved copy… updated the integration but it is failing when initialising. The error message I get is as follows: Failed setup, will retry: ‘pre-filter’. I have an Airmega 250S (AP-1720G) and it has a ”maintenance” value for both the pre-filter and the MAX2-filter both in the old IoCare app as well as previous versions of this integration.

| Coway Airmega IconS | Works Cloud | PM2.5 sensor added; no AQI or PM10Saved copyIconS devices don't report AQI or PM10, but do report PM2.5 both on the device's display and via the API. Add a new sensor for PM2.5. Also make sure we clamp the values for both PM10 and PM2.5 to 0 instead of empty string -- that squelches a lot of HASS complaints because sensors of type "measurement" need to be numeric. In order to reflect that 0 isn't a real measurement, mark the sensors as unavailable when the reported value(s) are empty strings. Finally, bump version to 0.3.0.
