Add ability to toggle heat range (ready <> rest) and heat mode (high <> low)?

[Warrior700]

Hi,

Is it possible to add a change function for heat range (ready <> rest) and heat mode (high <> low)? Or turn on the lights?

I'm a noob in C++ and it's hard to get into. I try to build it up on a M5Atom with rs485 interface.

I have added this in my fork:
https://github.com/vBrolin/ESPHomeSpa/blob/main/spa_reader.h
Gives you a service call for Heat and Range

Hi @vBrolin, I've tried to improve what you have. With these changes, you can basically create this yaml, you don't need to make the switches. It isn't clean, and basically does it by calling on Home Assistant to do the action, but it means no custom switches. That said, I couldn't figure out the thermostat for it.
