I have had a SmartThings hub for several years with various light switches, outlets, etc. connected. And I have also had 2 automations for several years…1 that turns on some outdoor lights at Sunset, and 1 that turns those same outdoor lights off at Sunrise. This always worked great in the past, and updated dynamically each day based off of current sunrise/sunset times. Sometime in the last few months this stopped updating each day. It still turns the lights on or off, but it’s stuck at the same time each day.
I tried deleting and recreating the automations and it would update to the sunrise/sunset time on the day that I recreated, but then gets stuck on that time going forward.
I also logged into the IDE website, went to my location, clicked on List SmartApps, and I don’t see any apps related to Weather or sunrise/sunset. But again this has worked fine for several years and only recently stopped working properly.
