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.

… 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.

README
Coway Airmega IconSWorks CloudPM2.5 sensor added; no AQI or PM10
Saved copy
IconS 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.
