Cheapest way to make 19pcs of thermostats and motion sensor
I would like to ask you how to connect 19pcs of temperature and motion sensor in the cheapest way (to control 19pcs of 2-way valves in the heaters). I have a cables in the every room so i can use them (i would like to install DSC alarm).
Is it possible to use Coco ACM-1000 to control 2-way valves? I think it is the cheapest, but not sure is it working.
Thanks in advance for helping.
