Improve switch behaviour and move binary_sensors to switches

This update is all about switches - the on/off methods have been reworked and are rock solid now.
Also, many former binary_sensors are switches now. Hopefully the last 'breaking change' for a while.

Please note: If updating from 2024.xx.x, please make sure to update your configuration.yaml as per this document.

Major rework - now using HA data update coordinator

This is a major code rework.

If you are updating, please read the following file carefully:
https://github.com/Tom-Bom-badil/home-assistant_helios-vallox/blob/main/2025.01.1_update_notes.md
You will need to change 2 lines in your current configuration.yaml.

I tested this code carefully in 2 independent VM's; however, please report back in the discussions if you run into any issues.
Thank you!

Use standardized ISO names for temperatures

Please note: Some sensors in the configuration.yaml needed to be renamed for this.
You might need to adjust your references to it in your templates and the front end.

Add new sensors with calculations

Included sensors for temperature reduction, temperature gain, temperature (dis-)balance and efficiency of the heat recovery.

Extra release as required by HACS

No changes, just for HACS listing.

v2024.12.6 - IP/port bugfix, refactoring of files

Merge pull request #4 from Tom-Bom-badil/prepare-2024.12.6

Prepare 2024.12.6

v2024.12.5 - First non-beta release

HELIOS VALLOX custom integration for older (pre-2014) house ventilation models.

Here we go - well tested locally, installable through HACS, and HASSfest tests give no errors or warnings.
Seems like we finally have made a HA integration.

I will now concentrate on translating and updating the docs, see Wiki.

Enjoy, and please report back! :)

v2024.12.4 beta - First public beta

This is the fourth beta and the first public release of the Home Assistant custom intergration for RS485-based Helios/Vallox central house ventilation units.

It is working properly for me, although not everything is yet fully implemented (grapical configuration and a standard Lovelace card are still missing, documentation needs to be moved and translated from my old repo, a basic configuration guide for common LAN/Wifi-RS485 adaptors needs to be created, etc).

However: Sensors, binary sensors and switches are fully implemented, so you can start working with all HA entities. Enjoy! :)
