Hi,
sorry to inform you it does not work on the 2148 setting.
I don’t think the led strip is addressable. It has the RGBCW channels.
Is there anything else I can do to test?
It’s better to cut them off at the end of a circuit, most of the time you can see a dotted line printed (sometimes a solid line) on it, or it’s in the middle of the copper “stripes” (as seen on the left side of your picture, even looks like it has a black line there, thats the spot to cut it.
After the latest update (test version 3.3.25) I can’t dim my AK001-ZJ200 anymore (have 5 of them). I can turn the ledstrips on and of but only at the latest dim level.
