The error is generated whether pushing the physical button or the Hubitat device button.
The interesting thing is that pushing the physical button does not trigger the linked RM button controller action. But pushing the button on the device page does properly trigger the RM BC action.
This is exactly why I promote Hubitat whenever I can. The fact you care about your users and listen to them. Shitting on them doesn't even cross your minds. Truly happy I went to you guys... (Now how about some HomeConnect integration so I can talk to my Bosch hood )
