Add polling and update miio

[arrizer]

I added polling device values every 5 seconds. This allows HomeKit automations that use a sensor value from the device as input to work. Without polling, a rule never gets executed.

I also updated the underlying miio module to allow for more devices to be supported.

some reason not updated the air quality and humidity. To update the data you need to close homekit and open it again. status of the inclusion is updated normally.
