Mi Air Purifier 3/3H - Property polling not working - Call to device timed out

[adahmen]

I have an issue with the device property polling for my Air Purifier. Token is correct - i checked it multiple times. Local IP is also correct. It worked after I switched to this plugin some weeks ago - but it stopped some days in the past.

Any idea what the problem could be? Any hint what to do?

[merdok]

Reason: Error: Call to device timed out might have multiple reasons... if you are sure that your ip and token are correct then you should try to reset the device as that might help.

[adahmen]

Do you mean a factory reset? Or what type of reset? And yes, IP is correct and token is correct.

[merdok]

yes factory reset of the device.

[adahmen]

A factory reset solved the problem (without knowing what the root cause was). Thank you !!!
