      ref: v3.0.0

use "v3.0.0"  , you have use "main". change it.
i don't know which esp32 board model you are using? i can't see in your photo.
maybe you can exchange RXD and TXD pin define.
Now do you INPUT port for binary sensor work well? only OUTPUT can't work?

I started with “ref: v3.0.0” and changed it to “ref: main” so I would always have the latest version. But it doesn’t work with either option anyway.

The INPUT binary sensors work perfectly. If i press a button, it registers correctly in Home Assistant.

It’s only the OUTPUT that doesn’t work.
