HATs and other add-ons • 230v input signal HAT

Hi
I'm new to this forum and Raspberry Pi in general. My son is all over this sort of thing, but we are looking for some advice on the best HAT to use to input a 230v signal.
We want a Pi4 to receive multiple 230v run signals from heating room controllers. IE, instead of sending the run signal to the heat pump, send it to a Pi so we can use some logic to run pumps, etc, via output relays. The main reason is that I want to delay the run signal to switch a motorized valve first.
We found a HAT with 230v inputs, but we need to check whether you can connect live and neutral straight to it as an endpoint or if it just reads the live power supply as it passes through; we haven't spoken to an electrician yet.

Can anyone advise if this HAT would work or what other options there are? We did look at just using a 230v to 3.3v power adaptor for each input, but it's a bit big and clunky. We're looking for a neat-packaged solution.

Cheers Steve
