I had the exact same thing happen to me and it was Alexa. I had changed an automation command and Alexa was still picking up the old automation. Go into Alexa a delete references to those bulbs and then rediscover them.
I was like you. It was driving me crazy and I just finally figured it had to be Alexa. So I deleted the bulb and the scene from her and then went back to my IRIS app and renamed that bulb Casper, after the friendly ghost, and that fixed it. Then I went into Alexa and rediscovered the bulb to set it back up there. I have that bulb and another included in a scene and when I changed the time the scene activated is when the problem started.
After you renamed the bulb and rediscovered it, did you keep the bulb name Casper?
I ask because I deleted the problem bulbs and some related scenes from Alexa and then rediscovered them without renaming them. Sure enough, the lights turned back on again. Perhaps I overlooked a scene or two in Alexa for removal?
My new plan is to delete these bulbs in Alexa right before 10pm to see if the lights still turn off. Then worry about rediscovery afterwards.
Yes, I have now just named the bulb what it was before and I am still fine. What I found out with Alexa is that when you do changes in your Smartthings app, changes that Alexa picked up on already, that these changes don’t necessarily change in Alexa. So, sometimes I will just go into Alex and review what is set up there and delete stuff that shouldn’t be there anymore. This especially was the case when I moved over from the Lowe’s IRIS system to Smarththings. The IRIS stuff was still all in Alexa even though I had deleted everything from the IRIS APP and then deleted the APP.
There could be a couple of different things going on.
First of all, it can take echo awhile if you were depending on the automatic discovery system. Saying “echo, discover new devices” will force a refresh, but even that doesn’t give you an instant update because there’s a cloud component to the integration.
So for testing, I would do the changes at least two hours before just to be sure they get picked up in the cloud and then do the Discover phrase 15 minutes before the actual test.
If I understand you correctly, you’re suggesting deleting the problem bulbs from Alexa 2 or more hours before 10pm, the problem hour. That is to give Alexa enough time to clear them from whatever memory or cloud they are kept, correct?
What is the significance of adding them back 15 minutes before 10? I would have thought leaving them out of Alexa completely before 10pm would be able to show / isolate if the issue is with Alexa or not. Does that not accomplish that? Perhaps I am missing something.
At this point, it’s just a matter of personal preference. Unplugging the Bridge would confirm That the problem is likely a rule somewhere, but it wouldn’t tell you anymore than that and it wouldn’t fix the problem.
If the rare situation occurred where you still had the lights coming on at 10 even with the bridge unplugged, then you would know that it was local interference from something. So you wouldn’t have to go through all the Amazon checks at that point. But again, that would be a rare situation given the exactness of the time when the problem occurs.
If you start by working through the Alexa options, you’re more likely to fix the problem during the troubleshooting.
Everybody has their own fieldwork style. I tend to work with the hardware first, but that’s not a best practices decision, it’s just the way my head works.
In Alexa, you can simply disable them. open each routine and at the top of the screen you have the option to disable that routine.
Going back to my 1st post - I mentioned it is most likely an automation, routine, smart lighting rule or piston.
In the STSC app, you have the ability to disable any custom automations and smart lighting rules that you have created. You can also disable (pause) any pistons you have created. Plus you have routines in Alexa. So I would recommend disabling in batches until you find the offending one.
This might seem like a silly question, but what is the STSC app? I ask because I use the SmartThings Classic app - the app with the blue circle. I also have installed the other SmartThings app - the one with that has what looks like a hub for a logo. I don’t really use that app, though. Is it one of those or yet another one?
Also, where in the app can you disable automations? I looked in Scenes, Routines, SmartApps, and the apps within SmartApps but don’t see any disable options in the SmartThings realm.
