I have a Simple Automation rule to turn two lights on at sunset and off at sunrise. It's been running fine. On June 25 I upgraded the hub firmware, and enabled Google Home and set it up. I played around with Home by telling my Google Home hub to turn lights on and off. Went to bed with the lights on, and next morning they were still on. I checked the log, and saw this:
2020-06-26 06:10:02.474 am infoDriveway Light is on [digital]
2020-06-26 06:10:00.860 am infoTurn Off Porch Light, Driveway at Sunrise -10 minutes Turn On
Prior to 6/26, the rule called "Turn Off ..." would turn the lights off, but when I checked it 6/26, I saw the action had changed from "Turn Off" to "Turn On". I changed that back, and it's worked fine since.
Has anyone run into something similar (a Simple Rule changing itself), or could it have been the firmware update, Google Home, or what?
