NodeMCU and WLED Issues with Powering via Mains Adapter
When powering the NodeMCU through the 5V mains adapter (Vin pin), the board doesn't start properly without pressing the RST button. This is likely due to power instability during startup or improper boot mode caused by voltage drops or fluctuations.
I suggest
1. Add a 1000 µF capacitor between Vin and GND to stabilize the voltage.
2. Ensure your power supply provides sufficient and stable current.
