That helps, l’ll try to find the manuals and see what if any options we have for you. UPDATE: The Samsung UK online support wasn’t able to get me pdf file manuals for your systems. … I’ll keep looking
Update2:
Found one. The bottom-line answer is it looks like you will not be able to control your AC units from SmartThings short of using a Aeon Heavy Duty Switch for monitoring the power use and on-off of the incoming power which I wouldn’t advise. You must use the supplied Samsung controls/thermostat. You got yourself a pretty impressive AC system my friend. It has lots of smarts and a great wireless remote controller to operate it. It also appears to have a Sub PCB option to allow for central remote control which uses the BACnet protocol. So maybe in the future SmartThings would be able to use the BACnet communications protocol for building automation and control networks. I was hoping there might have been a way to pass any input to the system to at least put it in a home/away kind of mode through the PCB but there isn’t enough info in the installation manual.
Update3: It is possible that this may be a alternative integration to the existing Samsung thermostat controls via remote control by IntesisHome? It is an intriguing solution that may interest you if the API becomes available. something to watch for. This came from E_Sch
