this is my first attempt at using WLED and I am a complete novice with it. My electrician installed the strip in a rooflight and I attempted to configure it in the app. I downloaded the beta (0.15.0-b6) and set the type to WS2805 RGBCW and the color order to GRB. Also changed the mA/LED to 30mA (typ. 12V).
it mostly works ok and the colors seem to be accurately reflected. However, after selecting an effect the first 3 LEDs stay white and even after turning the strip off in the app the first 3 LEDs are still on. I have to physically kill the power to the strip for them to go off.
Am i missing a setting or do I need to change anything else?
The power supply is 12v/25A and I’m using a dig-uno controller.
I’m having the same problem with a GLEDOPTO esp32 controller and a WS2805, and have the exact same problem. The first light group erratically changing colors, not responsive, stays on when turned off from WLED.
What i realized is tapping the backup data makes the flickering extend to later light groups aswell, makes me wonder if ut’s just the backup data cable getting wrong data and corrupting the controller data?
I got it to work by snapping the backup data cable and cleaning and reinstalling the connector cable, but the issue comes back every now and then.
Further testing, turning the light off/on doesnt trigger the flicker, but doing anything to change its state (edit: for example changing the effect, turning a preset on from off-status, changing brightness) starts the flickering again. Maybe it is just the data thats passed that is wrong?
Similar problem here.
My setup:
WS2815, 70 LEDs, 12V 5A PSU, NodeMCU ESP32, WLED 0.15.0-b7
This is just a test setup, so the ESP32 is powered by the computer USB.
V+ and V- from the PSU connect to the LED strip.
GND from the ESP32 connects to the V- and to the backup data on the LED strip.
GPIO16 connects to the data on the strip. Wires are very short (~15 cm).
When turning on the PSU, the second LED turns on solid white and a few other random LEDs flash quickly. Any changes to the effects or colors (even solid) just make a few random LEDs to flash. The second LED stays white.
Tried low brightness and decreasing the number of LED in the settings to 30 but got the same results.
Checked the wires for continuity and they seem to be ok.
OP here, apologies for delay in getting back. I (well my electrician) solved one of my rooflights by wiring the data cable differently. Believe there is an extra data cable that needed to be wired in to the controller differently.
