NSPanel with esphome

Hello i am trying to convert my nspanel from tasmota firmware to esphome following this setup

I’m stopped at line 826 which says:
tft_url:! secret nextion_update_url
but what does that url refer to?

and no space between “!” and “secret”

Sorry but not understood what I have to do …

Tell us what the error says.

not not how to complete the configuration, what should I put on the url line?

If you want to upload a tft file put the url of that file here.

I did point you to the docs.

Lots of info here on how to get it setup


oh yes I did it with this:

I would like to calibrate the internal temperature sensor, how can I do?
