Re: Homevision Relay boards ... Interested?
Brian,
It's not in use just yet, 'cos I'm still wiring the house. I'm going to
use
it to control actuator valves that supply underfloor heating and each
radiator. I'm using HV to measure the temperature in each room using
DS18S20 chips and then turn ON/OFF the radiators accordingly - temperature
setting dependant upon house occupancy, room occupancy, time of year
etc....
It's a nicely made board.
Simon
