Compilation error since update to ESPHome Device Builder 2026.7.0

I have some smart switches. They always gave following warning with compilation:

Compiling .pioenvs/lsc-powerplug-5/lib352/ESPAsyncWebServer/AsyncEventSource.cpp.o
/config/esphome/water-boiler2.yaml: In lambda function:

It won’t compile anymore (.state is removed). Who do I contact to fix this?

Thanks

HI.

You need to contact whoever wrote your YAML configuration — or simply update it yourself.

The compilation error points directly to /config/esphome/water-boiler2.yaml, line 207. Replace:

id(status_led_mode).state

with:

id(status_led_mode).current_option()

The complete line can be simplified to:

return id(status_led_mode).current_option() == "Normal";

This is not a smart-switch or ESPHome bug. Your configuration was using a deprecated API that ESPHome had already warned would be removed.

Kustonium, a big “Thank You”.

That solved the problem.
