Pretty much the default no_sensor config with hardcoded ssid/password.

I had to rename all the Scr/save and Scr/off instances to make it work.

Rob, this was a warning from 2026.1.0. Entities can no longer have a forward slash in naming as they are using that for urls. I think it gets enforced with 2026.7 or so.

cheers @chrisdunnname TBH i've not even plugged an S3 box in for months. I guess I should flash the latest ESPHome and iron out the creases lol. Thanks for the heads up.

There is also a compile error as below - hopefully you can help tidy that one up too, I'm not quite competent enough to work out what to fix with that one.

WARNING CORE.using_esp_idf was deprecated in 2026.1, will change behavior in 2026.6. ESP32 Arduino builds on top of ESP-IDF, so ESP-IDF features are available in both frameworks. Use CORE.is_esp32 and/or CORE.using_arduino instead.
