Can't get connected at web.esphome.io but can on other websites (WLED etc.)

Hello all,

I’m about to give up on this one.
On this page, it gets stuck at preparing installation:

When I go here: https://web.esphome.io/
The esp8266 never goes past “connecting” after selecting "prepare for first use)

My esp shows up as com3

I have also used the same esp on the wled web installer and it works fine.

Can you all give me a bit of guidance as to what is going on? I should be able to provide an additional information on any follow up questions you all may have to help me figure this one out.

This is the nodemcu I am using:

Additional info, hooked up a wemos d1 mini and is worked immediately on https://web.esphome.io/

I have around 10 of those 8266s, so I’m hoping someone can help me figure out whats going on with those or I guess I’ll have to garbage them sadly. :frowning:
Thank you all!

It sounds like you bought ones that have to be put in bootloader mode in order to be flashed. If that is the case, there is a button on the board that must be held down when it is initially plugged it. I can’t help on when exactly to let up on the button because I haven’t had much luck with the couple that I have bought with that feature.

EDIT: Zooming in on the photo of boards from Amazon listing, it does look like yours have the flash button indicated by red arrow. The blue arrow is a reset button.

Yeah, I haven’t been able to figure this out. They are real pains. I am considering junking them. I’ve spent at least 2 hours trying to get them working with the esp website.

I hate to be that wasteful but I’m running out of patience :slight_smile:

Thank you for your reply here @Stephenn

This doesn’t even seem to work.

I didn’t have any luck on that website using Brave browser. I had to use Google Chrome.

I have the same problem. I tried it with offline ESPHome_flasher (1.4.0), it works.

Ahh, was it with one of the Amica 8266s? It has a white background on the backside with their logo. Or was it with another brand? (Blue on both sides probably. Thank you ahead of time for your response.
