One LED is always on

Hi please advise, one LED has started to light up on my strip even though it is off ?? Can you advise me ? Thank you

‘Off’ just means color black. Your LEDs still have power even when off unless you physically cut the power to them with something like a relay. That one is likely on due to a bit of noise on the data line. In WLED, LED Preferences you can check the box for ‘Off Refresh’ That will keep sending the Off command every so often and that should help keep those rogue LED(s) turned off.

Hi, thank you. I will try. I have a board from Aircoookie, do you have any schematics to implement the relay? So that it can be started from the mobile application?

…now I tried for ‘Off Refresh’ but it doesn’t work. The LED is always on.

Bad LED.

… hmm, bad news, thanks anyway…
