Honeywell Thermostat webCore Piston stop working - Thermostat does not appear in webCore

I had a piston to control my Honeywell thermostat, but now the thermostat does not appear as a device within webCore, is there something that I need to do within ST to get the thermostat to appear in webCore as a device? It used to be there before.

if you can’t find it in your instance of webcore > available devices > available devices > capability group 3 > thermostat - then it may be related to the current issue on the ST platform.

Did you change the device handler?
