I had this same issue, didn’t want to plug it into my server.
I clicked ‘reset device’ and then tried to configure wifi again and it worked.
thank you soo much it worked for me.
thanks for the tutorial.
but i’m stuck, in after this Provisioned message, in Home Assisstant i get Improv via BLE to add. clicking on in, get message if i want to intall it and click send. After that it keeps running… after a while i get: invalid flow specified.
This worked great for me, thank you!
I had issues with the wifi not connecting properly but that was due to a weak signal.
It works! @mvana Thanks for your support!
It means that it creates a Wi-Fi network. It’s called something like esphome-web-F507B4 you can connect to that network, no password, with a laptop or you phone or what ever has wi-fi. Then check which IP you’ve got and use your browser to go to the gateway address. Maybe something like http://192.168.4.1.

perfect, your holding down of boot also works whilst you click continue! thankyou
Using Web - ESPHome this happens with version 2025.11.4 of ESPHome Device Builder - but not with 2025.11.3 - I upgraded - got the error, downgraded the error went away - upgraded the error came back -
I cant see how to log a bug report - it just goes roung and round in circles telling me to select which area -
So once I got the devices setup - wifi updates work fine -
I see the ESP32 device as an AP that I can connect to. When I do I don’t see anything pop up automatically. Help!?
Update: Turns out that if nothing happens automatically you need to find the IP address of the gateway of the ESP32, which is acting as an Access Point and then type that IP address into a browser address bar. Problem solved!
Perfect! Thanks.
If all the above solution does not help, you can try this
- Install esptool
- Add new device in ESPHome Builder and download the .bin file
- Flash the device with esptool
- Add the flashed device to ESPHome
- Test the wi-fi
