Temperature sensors throughout the building with centralized control?

Question

Sensors

Hello!
I am looking for a system of temperature sensors (preferably wireless wi-fi) with centralized control, i.e. so that there is one point where the data from the sensors will be sent. But this point processed the received data and performed certain operations. Let's say there is an office where the temperature should not be below a certain mark, and if the temperature drops below this mark, the system issues a warning.

Answer 1

I found a seemingly good program for centralized control, it seems to be ideal for our needs: www.benuks.ru It
remains to find the sensors themselves, I also found them, but they are too expensive: radioseti.ru/index.php?route=product/product&path=.. .
