Pixel LED-Stripe with Neopixelbus shut down random

I have a problem with my ESP8266 and the Neopixel. Randomly, the light just turns off. I also have a fan control, this all happens here too. But I can’t find out what it is either via the log or in any other way. Has anyone had this problem or have any ideas?

Sounds like a power/amp drop. What is powering this setup?
With 315 WS2812 you need at least a 18.5 amp power supply.

The setup is in a car with 2nd battery and a power converter: DC DC 8V-36V zu 5V Spannungswandler 10A 50W

Yep a power drop.

Well since it’s in a car and power options are limited to power pucks. I would try adding a power puck (or two) and power inject at middle points of the led strip.

Ok thanks I will test it.
What surprised me was that I have the same problem with my fans via GitHub - nordeep/esphome_fan_controller: ESPHome PWM FAN controller. They just go out after an indefinite period of time. Sometimes 30 minutes, sometimes 5 hours.

If I read the log it works mostly :smiley:

You need to look at the power and amp’s needed for that fan and compare it to what the the mosfet can delver. Is the mosfet getting very hot?
A sure sign the mosfet is working hard.

Okay, no, I wasn’t able to verify that
