Hi Mark,
We can’t help out with the wiring but to re-create a button press from a wireless system like the Clipsal unit you could use one of the logic level relays from this topic: Getting started with hacking your electronics
And some wireless device to interface with it. I’m not sure what the best solution may be but the one that springs to mind would be a home automation setup like HomeAssistant (sounds like youre getting there!)
Thankfully you wont need a sparky for this solution as well!
