Hi Martin, some of my addressable strips will not change color, either via the device color picker, nor via the set hue card in a flow. My diagnostics code is a84bf61e-f167-481d-9bca-e20e07dc44c4
The device is MHA Kit Counter AK001-ZJ2149 (192.168.1.198) in room Snug2. I also get time-out messages for many of my strips, but I have just upgraded my WiFi network.

Hey @John_Kevin
Did it work before ? Or is it a new controller?
Did you add it as addressable ?

Apologies Martin, I have worked out what was wrong. The LED strips identified as model AK001-ZJ2149 when they were included, and since there was no ZJ2149 in the dropdown list, I selected ‘other’ on some strips and left the model blank on others, but I realise now I should have chosen ZJ2148 as they seem to work correctly with that model number if using flow-cards (but still not color changing in the GUI) but that is not a problem.

@John_Kevin glad it works.!

Hi @martijn,

I’m still having problems with my addressable strips. Unfortunately I can’t change the strips as they are now built into my cabinets, but I have replaced the drivers with newer ones with no improvement. The latest SPI controller are very close to working but have a repeatable issue.

Setup:

  • Controller: generic WiFi LED SPI Controller (12–24V, ≤2048 pixels)

  • Strip: WS2811 (WORLDSEM WS2811 20220608), 24V RGB (grouped)

  • Magic Home app works perfectly (colour/brightness/on-off always reliable)

Homey:

Setting model to AK001-ZJ2148

  • On/Off :check_mark:

  • Brightness :check_mark:

  • Colour :check_mark: (initially)

  • After app restart → works

  • After some time → colour stops working, but on/off + brightness still work

  • Restarting app restores colour temporarily

Setting model to AK001-ZJ2146

  • GUI shows color and white wheel controls but nothing works

Repro:

ZJ2148 → restart app → colour works → wait/use → colour stops → restart → works again

Conclusion:

ZJ2148 looks like the correct protocol, but colour handling breaks over time. Control from Magic Home app stays 100% stable while Homey control is broken.

Question:

Does this controller need a slightly different profile (e.g. generic WS2811 24V), or could there be a bug in ZJ2148 colour handling over time?

Happy to test :+1:

Photos of my controller and strip are attached.

@John_Kevin that really sounds like a connection issue. can you send a diagnostic report when this occurs again?

Setting a colour using a flow card failed for pixel strips fails, but works for non-pixel strips. Also control by Magic Home app works at all times, suggesting connection is ok?

Also, there is a flowchart for non-pixel RGB strip driver AK001-ZJ2145 which is set a temperature, but this does nothing in my case.
