Since v3.4, the info about entity_id shown was going all the way to Nextion and then sent back in the json return, however this requires a long (100-char) global var and the way it was implemented, it was one of those per settings page, as climate should be also recorded at the same time in case the embedded climate was installed.
This was taking too much memory, so I've moved this info to a global variable (string) in ESPHome.
There is now lots of space for code cleaning (and still pending to do the same with climate entity, as it could be only a bool to inform if embedded), but this brings the functionality.
This enabled the return to global for some components, so it probably solves #1031
The touch event is used only for the sleeping engine (it will be used for dimming later) and it was transferring all the json info with page name, component, entity, etc.
This was replaced by a simple random integer with no meaning other than "the screen was touched, reset the timer".
- Removed a bunch of unused pics
- Changed page indicator to new format (which will allow future development to hide unused pages)
- Standardized close button in most pages
