Nope - it’s definitely a configurable parameter. Multiple forum posts mention disabling it for Home Assistant/Hubitat. If you expand the Firmware link at Resources | Blue Series Smart 2-1 Switch (On/Off & Dimmer) - Manual , under “Advanced Features” → “Parameter List”, it’s listed as the very last item.
There is a followup section labeled “Local Configuration”, but it’s empty, with no content. I assume those are the instructions I need to workaround the missing feature in the Edge Device Handler.
