Thanks @ RF Bridge

Thank You! I have “updated” my Experimental to Stable… And yes, the Support referred back to You.
For curiosity, was the RF Bridge the only affected device by the SDK change?

For my app yes, but it wasn’t the only app affected by the change. FWIW, it was confirmed by an Athom developer that they made a change that caused the issues.

OK, at least a sort of relief, that only one device in Your app… I was also suspecting the appearance of the new sw release of Homey to have roots in this issue…
