Just normal power strips for me. One that I can switch off pumps and all for water changes and thats all I really need. No need for automation.
That's how I was for a long time until I needed to go on work trips and make a "simple" process for my wife and then subsequently our pet carer.
My wife didn't like the idea of having to get under the tank or anything and I didn't like the idea of a tank sitter doing that either. I ended up needing to add *additional* automation as failsafes if the equipment was forgotten to get turned back on. Ask me how I learned of this failure mode
