Beta for Hysen thermostats powered by broadlink

@isodal, thanks for confirming. As to getting this into the official build I wanted to get most of the bugs out first, and I’m not in a position yet to do that for example I only have one thermostat so I am relying on others to test multiples. Also there is another hysen component that has been submitted for including in the HA, but not seen it yet in there Wifi thermostat (Beok, Floureon, Beca Energy) component
