Hi, my d1mini clone can connect to the wifi, and I can browse to the webui when powered via usb-(c) Could it be a power issue? And is it totally out of the question to connect the usb for a additional power boost? |

Plugging in both the P1-port and USB for power at the same time will probably be fine. They question is if you want to risk it considering you are missing with the power delivery to your residence... You could start by disconnecting the 5V from the P1-port and powering over USB only and see if that works any better. If it does, I would try placing a diode between the 5V on the port and the ESP! |

It does work as it should once i removed the 5v. Have to read up on the diode suggestion though, powering it via the port is the goal. |

How is it going to solve the power supply only via the P1 port? Any diode? |

If powering from the P1-port only does not work reliably, placing a large capacitor between 5V and GND on the ESP module might help smooth out the power enough. If that does not help, the module will need external power! In this case it might make sense to look at other, possible less power consuming, boards. Something based on the ESP32-C3 would be interesting to try! The diode setup (or something to that effect) really only makes sense for testing or if the board needs more power during startup and then can manage on the supply from the P1-port. In this case it would be possible to connect a power bank at startup and then disconnect it. |

Try to figure out how much current your board is drawing when it is working. If the current draw is excessive (more than the allowed 250 mA), that would explain why it can't be powered over the port. Some people, especially when using ESP32:s, have placed capacitors on their boards to smooth out any spikes in the power consumption. |
