Looks like this needs updating for latest esphome.....

I had to add

• platform: esphome

to piggymeter-common.yaml in ota section to be able to compile.

I managed to upload it after that but it looks like board is just restarting. I don't know if something is not compatible or is my board broken..
output is just:

Hi,

It seems that the chip wasn't flashed correctly. I noticed an issue with C3, but I'm not entirely sure what's wrong. One time, it programmed successfully, but on another attempt, I couldn't get it to work.

I switched type from esp-idf to arduino and now it works.
(I am noob with esphome so I don't know what it means)
