TP-Link Tapo L900-5 led strip not working properly
My led strip has been working flawlessly for the past 4 months since I purchased it. However it has started misbehaving 2 days now.
The first problem, a major one I have to say, is that now it is impossible to switch off the led strip. No matter if I try to switch it off through the app or through the controller, the led strip turns blue and stays there while reporting off. The only way to completely turn off the strip is to unplug it from the power socket. The second problem I noticed is that the strip no longer produces yellow color. Yellow now appears as white with a light yellowish hue. The third problem is that when I dim all colors to 1%, they all become blue, even white!
I have tried the following but they did not solve the 2 problems above.
1. Reset the strip
2. Reset to factory defaults
3. Removing it from the Tapo app and adding it again
4. Unplugging the power for more than 24 hours
5. Unplugging the power for more than 24 hours after resetting to factory defaults.
I can successfully complete the process of adding the strip to the app, however there is something that relates to the second problem described above. When the strip is reset to factory defaults, it no longer lights orange and green when powered up but rather white and blueish. In the app "not orange and green" does not provide any help at all, so I just select "already orange and green". All other steps are successful and the led strip is added normally, although the 3 problems described above remain.
My main problem here is the inability to switch off the strip. A serious secondary problem is that when dimming to 1% all colors become blue. I do not care about the yellow color so much but not being able to switch off the strip or dim to a desirable color is a dealbreaker for me. I suspect the led strip or it's controller are defective. Is there anything else to try to solve the problem or should I return the strip back to the supplier and ask for a replacement?
One last thing. I might be able to determine if it is the controller that is causing the problems. I have another 3 strips I have not installed yet and I could test the controller of another led strip. So if I eventually replace the controller with another and the strip works properly, do I also need to return the led strip to the supplier or can I only return the controller for a replacement? The reason behind my question is that the strip is stuck on a painted wall and removing it might cause some damage to the paint.
