Last night, before falling asleep, decided to polish WHS2 setup, just simple "nice things" :lol: : - Updated connection with WTH thermostats from "Switch toggle" to "Switch On/Off" - Updated function for one of thermostats connected to WHS2 from "Clima" to "heating" Tested - does not work . WHS2 do ...
