I just go an alert that my Living Room Motion Sensor sensed motion while no one was home. It is a second gen SmartThings motion sensor. I looked at the logs and saw the firmware was updated. Took approximately 10 minutes to update and when it came back online, it triggered the Dashboard to alert me of an instrusion.
I have three other sensors like that one, that didnt get any update.
Same happened to me! First time ever while I was at work. Was looking all over house with cameras. All checked fine. Then I looked at logs and saw the same thing.
