Lets see if the code populates here correctly. Aside from the code I also have an automation in home assistant such that if the temp sensors become "unavailable" for 30s or more, all affiliated smart plugs are shut down. FYI this controller is set up for two different ferm chambers "Brown" and "Keg"
