Hi all,
I am new to the forum and home automation so some of my questions may be pretty basic!!
When I build my new extension I want to add some automation and at the moment I am going through the research phase. So far I have set up Openhab with an MQTT server an I am using this to control some PCB based 5v relays (via Arduino) that can be used to switch loads. I understand though that it is more usual to have 12v DIN mounted relays and I am therefore wondering how best to use the 5v relays to switch a 12 v load to the DIN mounted relays - does anyone have any advice on this please?
Thanks
D
