Shelly H&T Gen 3 Control from C4

[Dave Bowen]

I have a shelly H&T Gen 3 that I am using to turn a Shelly Plug on and off to control a little heater.

All works fine of the Shelly App / Cloud and the plug changes state to reflect the measured temperature v set point.

I have brought it into C4 via the Shelly Agent, but for the life of me, I can't turn the stat on or off, change the set point etc.

 

It's driving me absolutely nuts
