Hello, I am currently building a new house, and I want to have a great blank canvas to begin with. I already have a home battery with solar installed, and plan to automate with this using Modbus TCP.

I am wanting to automate hot water tanks, backup water tank filling, automatic garden watering and anything else I can put my mind to.

What do you think are must have considerations I should have before going down this route, such as devices I absolutely must install (such as smart relays) etc.
