Hi,

I have an issue very similiar for #383 however the root cause is different than it was in the #383

>>> from miio import AirHumidifier
>>> h = AirHumidifier("192.168.1.20", "b3026a0a55390cc375de32c550axxxxx")
>>> h.status()
Traceback (most recent call last):

h.info() works fine:

I've performed steps from the mentioned ticket:

One property is retireved properly:

>>> h.send("get_prop", ['power'])
['off']

info and status cli commands work well:

You should use the device specific class:

from miio import AirHumidifierCA1
h = AirHumidifierCA1("192.168.1.20", "b3026a0a55390cc375de32c550axxxxx")
h.status()
