[OBSOLETE] Xiaomi Sensors and Button (beta)

@a4refillpad The temp colors is different than on my other temp devices like Fibaro,Netatmo etc.

I use C, and at 22 deg I get a orange color on your handler, green on other devices

I changed line 62 to : attributeState("temperature", label:'${currentValue}°',

and line 93 to: state "temperature", label:'${currentValue}°', icon: "st.Weather.weather2",

Now the colors seem to be converted correctly to C and matches my other temp devices
