In my case pressing Reset button solved it

I pulled them out of use. Was not able to get them working.

I ran in to this problem today after not upgrading for over 12 months. A reboot did not help.
I was fretting at the thought of having to climb in the roof and flash everything over USB.

I had success though by commenting out everything that wasn’t in sections esphome: wifi: ota:
I was then able to add the rest of my config back in after flashing the minimal config

Hope this helps someone else…
