My Smartthings system and Konnected boards (2) have been humming along fine for about a year now. Very recently both the door "buzzer" and the 12v strobe on the Konnected board stopped working. I powered down the boards and restarted but no change. The door switch that triggers the buzzers "beep" is opening and closing properly (electrically speaking). Both boards display a steady green LED once they are rebooted.
Nothing has changed recently in the way of any wiring or adding devices to Smart Things. Any suggestions for further troubleshooting?
