Hello - just noticed a small issue on all of the 8266’s I have tried. I have loaded WLED 14.4 on an 8266 (several actually) and attached a string of 50 pixels. When powered on, the first 13 LEDS briefly light up as white before the solid amber default kicks in. This is not normally a problem, but if I reduce the configured number of LEDs in WLED to under 13 - like 10, for example - then power on the controller, the first 13 LEDs blink white, and then only the configured 10 LEDs change to amber. The next 3 remain white since the controller isn’t aware of them. I have tried ESP-12E and ESP-12F 8266’s from different vendors. All seem to exhibit the issue. I have loaded 13.3, 14.0-4 and 15.0 b4 - all exhibit the same issue. Tried 80MHz and 160MHz - issue seen on both. My ESP32s, however, seem to run fine with no white blink on power up. Has anyone else seen this problem? Here is a link showing what I describe. In the video, I am using a Duo2Go 2-port controller with an 8266 attached, but I have verified that the same issue occurs when you bypass the controller and power eh lights directly from the 8266. When powered on, you see a brief 13-LED white blink. Then, the first 10 change to amber, leaving 11-13 white. If I were to reduce the LED count to 1, for example, the reboot. The first 13 flash white. Then only the first pixel goes to amber, leaving 2-13 white. This happens on BOTH outputs.

The best if you contact board vendor and ask him what can cause your problem. ---

Their design likely causes some noise on the data line before the esp starts driving it. ---

I have tested this with several different ESP8266, bought from different vendors. As I continue to research - I see the same issue here: > [@Startup often lights a few bright white](https://wled.discourse.group/t/startup-often-lights-a-few-bright-white/10705): > > I have this weird thing going on. I’m relatively new to 12v WS2815 strips but I’ve had a 5v 2811 running non stop for about 4 years. The situation. I want to have a WS2815 as programmable accent lights on my car. I want them to come on when I hit the brake. So, obviously, I will need to engage the brake to switch states. I’m prepared for that. Here’s the problem. I programmed a NodeMCU to do the effect. When I turn off power (brake not engaged), it goes off. When I turn the power on (engage… Sounds like it is being chalked up to “garbage on GPIOs 2 and 1” (my two outputs) at bootup. Is there any practical way to mitigate? I have a full setup with level shifters in place. Overall this is not a terribly severe issue - but an annoying one. It only presents itself as a problem if you are only running less than 13 LEDs, and have extras after that you don’t plan to use and don’t want to cut off. ---

ESP32 does output PWM/gibberish on boot on certain pins but I didn’t know the 8266 did too. Easiest would be to use ESP32 based contollers, 8266 really shouldn’t be used if buying new these days. ---
