I’ve noticed that ALL of my lights are turning off at 1:00 AM. Not at 12:58 or 1:06, but a few seconds after 1:00:00 AM (usually 1:00:30 to 1:00:45). Never strictly before 1:00:00 AM and always before 1:01:00 AM. They’re not disconnecting, just turning off. I’ve searched for timers, scenes, routines, webcore, Alexa and can find nothing that should be doing this.
Smartthings is the only zigbee hub I have. I did a test by turning one light on in the evening and then deleting it’s device from smartthings and it stayed on all night. These are mainly Sengled zigbee light bulbs but there is at least 1 non Sengled bulb.
Oh, I happened to look at Alexa routines and found a routine to turn all lights off at 1AM, and it was enabled. I have no idea where this came from and am sure I haven’t seen it in the past. I wonder if poking around in Hunches yesterday added this routine to Alexa?
I’ve talked with one of my sons who has access to my smartthing device. He found the same routine you mention that has appeared without his knowledge and is causing the same power off function at his residence. He has disabled/removed this routine so we’ll see what happens in a few hours.
We are theorizing that since he has access to my device, his Alexa is sending the power off to my device.
If this doesn’t work my next step will be to unplug Alexa before going to bed and see what happens.
Then his Alexa account may be seeing your devices. The SmartThings Alexa skill (still - even though the feature was promised over a year and a half ago now. ) presents all devices in all locations you are a member of.
Soooo if he is a member of your location (there is no administrator concept in a ST location - just owner and member, but member is enough fof this behavior.) you absolutely have to look at his Alexa account as well for routines and such as they can impact your location unless he’s carefully disabled all of your devices in his Alexa account.
For instance, if a routine suddenly shows up to turn off all lights at 1a or something. ;). All would include YOURS
