same issue, HA 2023.11.2

[zollek]

Same issue here for zhimi.humidifier.cb1. This error is a cause of device disconnect.

[rytilahti]

So, this happens when the device responses with something that is not a json object. It would be very helpful if you could try to access the device using miiocli -dd airhumidifier --ip <ip> --token <token> status (note two ds) to trigger https://github.com/rytilahti/python-miio/blob/9b17d906d3829dd861d4cb73982dad7d9a5a8e95/miio/miioprotocol.py#L197 find out what is going on.

You can locate the token either by using miiocli cloud command or extracting it from the config entry file (~/.homeassistant/.storage/core.config_entries).

[zollek]

Hi, I was finally able to set up python environment and could run miiocli: zhimi.humidifier.cb1 status.txt

If there's anything more needed just lep me know.

[quenthal]

are more logs needed? i've two smarti humidifiers that are "suffering" from this same issue.

(These seem to happen (only) twice a day, so naturally not with every status update or something like that)

[rytilahti]

No need for more logs, if this is not something that is happening for every update. I created an upstream issue to track this https://github.com/rytilahti/python-miio/issues/1913, but in the meanwhile, maybe we could catch that typeerror and just log it instead of erroring out?

This wouldn't fix the real issue (most likely some fw issue), but it could make it less annoying when the device is just marked as unavailable instead of throwing an exception.
