Your Automation is almost certainly causing this. Your Imgur link shows that you have two Automations active, and I think the one shown in the second image is the problem. You have it set to trigger on motion and turn on the light for 5 minutes. At the end of 5 minutes, the light will turn off, and that change in light causes a massive change in pixels detected by the Cam v3 (which is what the big green box in your image here in the topic shows, so good on you for having Motion Tagging enabled), and that triggers the Automation again, so the light turns on for another 5 minutes. It’s going to do this all night.
The first Imgur image shows a schedule Automation that’s also turning on the lights, and the time you have set for that indicates that you want the light on for more hours than you want your trigger Automation to run, so I’m not sure what you’re trying to accomplish here. In other words, if you’re telling the light to turn on with a schedule and then sometime after the light is on you want motion to turn the light on, then what do you actually expect to happen? I don’t really understand what the goal is.
To prevent the cycling, you could try to shorten the “Turn on for” time in the trigger Automation. If you’re triggering on generic motion (pixel change) because you’re not subscribed to a plan (Cam Plus or higher), then maybe see if tweaking the Action beats the 5-minute cooldown. If you want light only when triggered by motion detected by the Cam, then disable or delete the schedule Automation when you do that.
I don’t think it’s a true conflict, but I don’t disagree with turning off the sunrise–sunset schedule, because I don’t think that’s helping. I think you should turn that off and shorten the “on” time for the Bulb and see what happens.
The Quick Start Guide should include URLs for both the Support site (Help Center, linked in my previous post) and Wyze’s Community page, the latter of which links out to the Forum (here) and their other social media communities/accounts. The QR code also contains a link to the Support site. Additionally, you can access Support through the app ( Account ➜ Wyze Support), but I’m not a fan of typing on the phone, so I tend to hit the Support site in a PC browser. If you ever need to follow-up on a log submission or inquire about a warranty replacement, then you’ll have to go through Support.
I think a lot of us within the community like to answer questions, so I like to believe we can be a good resource, but we can’t do some of the things official Support can.
That’s because you’re new here, and your profile shows that you’re still “TL0”. If you choose to spend just a little more time here (it doesn’t take much), then you’ll be able to do things like attach more images and even videos.
You’re welcome! I hope this helps!
