HA 2021.9.2 (nwt.derh.wdh318efw1) - AttributeError: 'AirDehumidifier' object has no attribute 'device_info

[peterhoe]

Have tried with both V0.6.11 & V0.6.12

Was functioning fine with HaasV2021.8.8 using V0.6.11

On updating to HaasV2021.9.2 i started seeing this error

pythion-miio has changed a bit. This custom component needs to be updated to be compatible again.

Same problem on deerma.humidifier.mjjsq after update HA on V2021.9.2

Anything I can do to help?

If you give me an example on one device what changes are required, perhaps I can go through and amend?

[syssi]

Go to the release page of the python-miio repository and take a look at the diff file of the last releases. device_info should be mentioned here. Was it removed or moved? Adapt the custom component to access device_info properly again.

[syssi]

@rytilahti Could you help me here? It looks like device_info isn't available anymore as property of the AirDehumidifier device class. Probably just an initialization is missing? I don't understand this line because of my limited python skills:

https://github.com/rytilahti/python-miio/blob/master/miio/airdehumidifier.py#L177

I would like to replace this line by

        self.device_info = None

to fix the issue.

[rytilahti]

@syssi oops, the initialization is indeed missing, that slipped somehow through the cracks when the variable got type hinted. It should look like this: https://github.com/rytilahti/python-miio/blob/master/miio/airhumidifier.py#L265

[nielsfaber]

Having the same problem here.
If I understand correctly, the problem is caused by the version of python-miio which is included with HA?
Is there any way to quick-fix this myself locally?

[syssi]

Fixed.

[peterhoe]

Confirmed functional with V0.6.16 & Haas V 2021.12.3
Thanks Syssi & rytilahti
