You can get the flush fit LCD keypad for the euro 46 which look quite nice and come in different colours.
It's what I'll be fitting in my new home shortly.
Use existing wiring for a hard wired system with all the other features surely?
Hybrid system to give use of remote setting etc.
I'd be fitting something like a pyronix euro 46 app or a Eaton ion 40h if it was me.
