@chevrolux you're braver than me haha, I have 2 sonoff's in our place at the moment just on extension cords but not keen to be running them in the new house. I do love Tasmota though.
I'm using Home Assistant for a number of other devices so integration with HA is pretty high up on the list for me, followed by price and then probably security.
Sounds like, for a centralised solution you are required to use their switches/control surfaces, anyone know of anything that integrates with Home Assistant?
One other advantage of relays behind the wall plates is the ability to expand over time and take them with us when we move again, think I've convinced myself that's the best solution for my scenario.
What Z-Wave relays are you using @davidcole, are you seeing issues with them causing you to recommend a centralised solution?
