It looks like a grounding issue? Did you attach GND properly?

Seems to happen with new ESPhome release ....

EDIT .... erratum everthing is ok with last ESPhome release & arduino lib :)

If you have the chance please try a ESP32 instead. I guess this platform isn't affected.

Let's close this issue. Hopefully it's resolved.
