The problem

I am using the Olimex ESP32 PoE Board with four ac_dimmer outputs - all share the same zero_cross_pin. It worked fine last year with ESPHome 2023.X

I wanted to update the firmware within ESPHome 2024.X - compile error

Which version of ESPHome has the issue?

ESPHome 2024.X

What type of installation are you using?

Home Assistant Add-on

Which version of Home Assistant has the issue?

2024.2.5

What platform are you using?

ESP32

Board

Olimex ESP32 PoE

Component causing the issue

ac_dimmer
