Improve Nibe integration (Modbus TCP) SMOS40

This integration provides quite a few sensors. Most of them are deactivated. Others are not. Based on the name, it is often impossible to find out what the sensor does at all. Often sensors are irrelevant or do not work. There are also sensors with the same name or similar. It is almost impossible to match the operation on the display. The worst is when they are writable values. I can’t find an easy way to set the operating mode, for example. Sometimes it just says 0 or 1 or 2 or whatever. But I have no idea which value does what. It is also not documented. This integration is very adventurous. Some things I found out after a lot of searching, trying and comparing. But not the most important ones. So I still have to rely on the myUpLink app from Nibe if I want to change something.
