Good Morning I'm a beginner in this arduino world. My plan was to optimize my home in terms of energy efficiency. So you needed to know the temperature / humidity in all rooms of the house, (in a later stage on / off AC) and also in the AQS system know the water temperature to switch on / off electrical resistance. I think it would be an interesting project.
In my research I think it would be possible through arduino, but I have some doubts: Is it possible to connect several temperature sensors through the cable, several meters away? (Arduino was in a central part of the house) As well as the system required, to obtain the water temperature of the AQS, On / Off Resistance.
I count on your wise opinions.
