Hi there, I have 5 different wled projects around my house, each one using individually an esp2866 as the controller and ws2812b leds, my shortest project is about 30 leds and my longest one is 460 so I have different power injections and amperage for each case but the controller and the leds are the same and I have the same issue with all of them: when I unplug the power source or the power goes out in my house and then it comes back only the first 2 leds turn on the first one green and the second one white, this is fixed “easily” by unplugging the data wire from the esp2866 then pressing the reset button and plugging it back then the leds turn on normally, I’ve had these projects for over a year and at the beginning it wasn’t an issue but lately there’s been several power blackouts in my area and it’s becoming an issue without mentioning that I can’t have more of a permanent installation in my projects, any ideas? I’ve thought of changing the esps for 32 instead of my 8266 but I’m not sure if that could solve the problem
Those LEDs are ON when you have WLED set to OFF or that is all that lights up when WLED is turned ON?
Those leds are ON with Wled OFF, actually the device appears offline in the app until I do my “manual reset” by unplugging the data, reset the esp and plugging data back, that’s when the whole strip lights on and it appears online in the app, btw I discovered my “manual reset” by fluke, it was driving me nuts since nothing else seemed to work
If you leave the data connected and power cycle the Esp are you able to access WLED or do you have to power it up then connect the data?
The esp has 2 buttons one for reset and the on/off button, there’s no problem if I push the On/Off button, the LEDs turn on and off without issues, I’m not sure if that’s what you mean by power cycling the esp, the problem comes when the esp loses power wether the power goes out in my house or if I disconnect the power source of the esp it’s the same result, btw some of my esps are powered with a miscro usb cable and the ones controlling more leds are powered with wires soldered directly from the power supply tu the 5v and gnd pins and I have exactly the same issues in both cases
Do you have a power up preset configured in WLED?
It may be worthwhile to make an “Off” preset and use that under Config->LED Preferences->Defaults->Apply Preset at Boot
You might also check the “Off Refresh” box in the strip configuration section.
hI @razthelizardking, I was also facing the same issue as you (2 leds at boot when data pin is connected), The reason could be that your GPIO pin is overlapping with the system led pin. I would suggest you to change the GPIO to some other pin as you were using before.
In my case, I had a esp01 controller and was using GPIO02 before. And now changed to GPIO03(TX) and my led’s works fine now.
Hope this helps
