I have installed a peizo buzzer (Konnected Switch driver) and it will not update on the devices page. The device works properly in that I can turn it on and off from the device page or a dashboard. Except, it will not update to the proper icon on a dashboard because it does not update the state of the device. It does show up in the HE log. I have deleted it and re-intalled it (multiple times). I have rebooted my HE hub. I have rebooted the Konnected device.
Don't know if this helps, but...
My solution was to remove from Hubitat the Konnected board that had the buzzer connected to it. Then I re-installed the board through the Hubitat Konnected install process as before. The buzzer now works as a Konnected Switch and is updating properly.
My above solution has failed again. The Peizo buzzer has stopped updating. The buzzer will work correctly (and update) for a short period of time after I re-install the Konnected board. Then it fails to update. I can turn on the buzzer, and it works. It just does not update the status.
