I have a 3D printed clock project I’m working on, using ESP8266 and WS2812B strips (30) and everything is working well with my code and lights, except for one odd issue that I’ve noticed.
If I power on (powered via USB-C on a PC) the ESP8266 with the strip disconnected, wifi connects and I can see the device in ESPHome. However, if I power on the device with the strip connected, the strip lights up led0 green, and led1 white. Wifi & ESPHome do not connect. I can see the COM device connected to my PC, but I do not get any log feeds with ESPFlasher (my ESPHome server is running on a separate server, via Docker container)
I have read that this may be related to a ground issue, or I may need a external power source, but I’m not sure why that’d be required considering everything works, as long as the ESP8266 is powered on with no power draw on 5V.
Obviously this issue is a bit of a pain, I am hoping to seal the casing once everything works, and having to unhook the strip every time the device restarts would suck. I am planning to use a USB wall wort (5v 2a) to power this once it’s all working as expected.
Any advice is appreciated!
