Its the tone of voice. I see that being done more often… edit: sorry, I see you pointed that out.
On topic; thanks. I have see multiple suggestions for elements within the system, Yes. But I don’t have to have one brand. Different products from different brands is fine. Valves and (I think) relays are the basis. But then it also gets tricky; 24v ac, 230v ac, Etc. Which relays, and how to use them outside.
Would a basis of a magnetic valve and a relay per zone be enough to setup a smart system? Or am I forgetting about something?
