I have a basic rule that turns on my front lights at Sunset and another rule that turns them off at Sunrise. Its been working fine for over a year. Recently it turns them on at Sunset and turns them off a few minutes later .
Here is the on rule..
Maybe database corruption? @terminal3’s suggestion might be the fastest solution when combined with @sburke781’s.
If you want to spend more time on this, another things that you could try, if you are on the latest platform version, is to do a reboot while checking the rebuild database option, and see if that makes a difference (in case there could be database corruption).
Another good idea would be to enable logging on the rules to see if there is anything unexpected happening.
In addition to checking the devices involved and any automations, make sure the timezone is set correctly on the Hub Details page, plus check the Sunrise / Sunset Events are happening as expected in the logs.
Is it just the Front Lights that is turning off at the wrong time or is Front Patio also turning off? Would you post the device events for the Front Lights?
