Hi,
First off, I don't have any formal background related to neither electricity nor electronics. So please don't come back hard on me.
I am in the process of wiring my new home, 3 bedrooms, 3 bathrooms, a dinning room, a living room, a reception, a kitchen and a laundry.
After researching home automation and wiring topologies, I decided;
A) Install a total of 50 light switches (10A breaker per room),
6 air conditioners ( 6 relevant breakers),
7 roller shatters, and
15 outlet circuits (8 outlets per circuit per room with a16A breaker , except for the kitchen and the laundry only a single outlet per circuit with 20A breaker each)
B) Go with the star configuration topology for the mains wiring (220v) to gain flexibility when deciding on the automation hardware and rewire to normal if necessary.
C) Install 2 flush mounted distribution boxes, one for the main isolator, circuit breakers and RCDs, the other box for the automation solution.
I got one Shelly 4 Pro pm shipped internationally to toy with, however in the process I discovered new import regulations for IoT devices that will make it hard to obtain more Shellys in near future, unless a registered distributor settle the paperwork and import large quantities.
A long story been told,
Can I just use the 4pro pm with 4 large enough contactors one per channel as follows
Channel 1 kill all lights
Channel 2 kill all outlets
Channel 3 open all roller shatters
Channel 4 close all roller shatters
Sorry for being to much into details.
