I just got an alert for one of my smoke detectors. My wife was nearby and ran home to check on things and I searched through the event history to see what was going on. There was no problem when she arrived.
Although the dashboard showed a Smoke Detected alert, the history for the smoke detector itself showed this:
2017-04-06 12:53:47.116 PM PDT
9 minutes ago DEVICE alarmState clear Downstairs Smoke Alarm smoke is clear
Nothing in the history showed smoke detected. Why would a clear event trigger an alert? I actually don’t even see an alert for today in the Smart Home Monitory history…
Might it be a bug in the new firmware?
