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.

Hello, i've tried to modify the files for my AirPurifierPro, but i didn't get more update, i need to re-load Home to run Automation. A conf.js file modification is it necessary to enable this future ?
Could you help me please ? Regards

Just my 2 cents question. How can I update the plugin installed on my server with your pull requests (I see 3 changes in total)? The plugin author is not active for years so it’s good to see someone updating this great plugin like this.

Thank you very much though
