core: Miio integration stopped working in 2021.12 (unsupported operand type(s) for -: 'NoneType' and 'int')

Confirming the issue.

That is a different error, so please keep it out from this issue. Looks like you are running an old python-miio version (maybe you have some custom component enabled which pins to the older version?) which is causing this.

Confirmed

Similar issue with ‘philips.light.candle2’ which no longer works since 2021.12 update:

@rytilahti Could you please describe how to test the fixes? My problem is with the philips hbulb, I could test those lights.

@fereehu I have the same problem as you. In version 12.2 the hbulb do not work, after downgrading to 11.5 everything works again. Did you manage to solve this problem?

Ok, I have found. It works with “philips.light.mono1”.

https://github.com/rytilahti/python-miio/issues/1231#issuecomment-995282665

Ouch, looks like github supports cross-repository issue closing now? That was not done on purpose…

Anyway, the fix requires a version bumping python-miio so I’m waiting for someone to confirm that the fix is indeed working. It makes no sense to prepare a release, bump the version etc. just to find out otherwise.

Same problem here with Xiaomi gateway chinese version

This is a duplicate of #61427 I think.

The miio.exceptions.DeviceException: Unable to discover the device None is related to gateways and is being fixed at https://github.com/rytilahti/python-miio/pull/1233 and is unrelated to this issue as far as I know.

indeed, alarm_control_panel.xiaomi_gateway_alarm entity is “unavailable” for me too.

Hey there @rytilahti, @syssi, @starkillerog, @bieniu, mind taking a look at this issue as it has been labeled with an integration (xiaomi_miio) you are listed as a code owner for? Thanks! _{^{(message by CodeOwnersMention)}}
