Easy Nextion Library

Hello @mattyra,
Your questions are justifiable and the answers have already been given at this thread Easy Nextion Library - #53 by Seithan

  1. I have not found any other way to send or receive float values, except for this one.

  2. There is the EEPROM of Nextion, where you can store and read data. This is a little difficult, as it requires a lot of general programming knowledge. Unless you have an Intelligent model of Nextion and you can use the dataRecord component. That way it is a little easier.

  3. As for the slider, it can be used to send a number to MCU with a simple trigger() function, that would contain the readNumber() function. myNex.readNumber("h0.val");
    maxval should be set to 12 and minval to 1 on the slider's properties

  4. Every value can be sent from ESP to Nextion and from Nextion to ESP

It seems like an easy project but it needs a lot of work, because it looks like a big project. You can do everything you want for the project and find many answers to the library's documentation and examples.
