Just find out that you can try to add the Honeywell Total Connect Comfort service to smartthings. Got so exited and then it said that it could not Connect to smartthings service…
I hope it’s finally time…
I use Honeywell TCC to access my Honeywell thermostats from SmartThings.
Try initiating the connection from ST.
I have my Honeywell thermostats linked to ST as well. You have to initiate the link within ST.
Connection from smartthings just fails for some reason
