You do not have a touchscreen: section.

Also - a quick search of the forum comes up with this:

thanks, already tried it before, but it compiles with error due to changes in last esphome.
Also my board has ST7789V instead of ILI9341. Both problems were fixed using chatgpt,
concerning touch, if I add touch section from the example, error is
Couldn't find ID 'touch'. Please check you have defined an ID with that name in your configuration. I’m not familiar with this… may try chatgpt again, but it usually cause new problems

This works with the version of that screen I have.

tried, got ERROR Running command failed: This chip is ESP32 not ESP32-S3. Wrong --chip argument?

I linked that post for you to look at the touchscreen component, you stated you already had the screen working.

Did you read the ESPHome docs I linked for your touchscreen? The touchscreen component requires a SPI configuration, which is in the example I linked.

OK, sounds like they changed the screen in your version. It’s not the one I have. It would be good to see a picture of the back of the screen and also a link to where you got it. That way the community can help you get it working.
