Mi Air Purifier 3H issue #175

Closed rgreco87 closed 2 years ago

rgreco87 commented 2 years ago

With your plug-in, my Mi Air Purifier 3H becomes unresponsive and can’t be controlled through both HomeKit and Mi Home app.

Well with the little information which you provided i suspect that it might be due to network issues on your side. It might also be that you are sending to many requests to the device in that case you would need to reduce the polling interval.

This is what I see in the log:

I already changed polling interval from 7 (your default value) to 10 seconds but I still got this error.

"Error: busy" means that the device is getting to many commands. Maybe you have different software accessing the same device, other plugins maybe? You need to even further reduce the polling interval then. You can also try to reset your device which might also help here.

I already did a hard reset and I have no other plugins related to Mi Air Purifier. I reduced polling interval to 5 seconds, let’s see how it will work.

There is nothing i can do about the Error: busy message, this basically means that the device takes a lot of time processing commands, maybe you have other devices pinging or sending messages constantly to that device? You should set the polling interval to maybe 20 or 30 seconds to be sure.

No, as I already said I have no other devices pinging to Mi Air Purifier. I had no issue using other (old) homebridge plugins for Mi Air Purifier 3H, it just happens with yours.

merdok commented 2 years ago

If that is indeed the case then the only thing which i can recommended you is to set your polling interval to 20-30 seconds (maybe even higher). I guess your device does not like to get contacted often...

I have a new issue since you updated your plugin to v1.0

merdok commented 2 years ago

For user ack timeout you should try to reset your device.

I already did it yesterday and then I re-added to your plug-in with the new token. So this is NOT the solution.

merdok commented 2 years ago

You are spamming your device too much with request. No idea from where they come. This is not an issue with the plugin but with your device which is just getting too many requests. You have to investigate your network and find the fix. There is unfortunately nothing i can do about it.
