When the builder built my house they put in a honeywell system with a vista main board and a couple of control panels with keypads a 2-line display.
I know I can replace the main board with a konnected pcb. I’d rather not remove the control panels when there is nothing to replace them. They are mounted in the right places to be able to arm and disarm the system. It would be great if konnected could support the panels. I suspect others are in the same boat when it comes to what was installed before.
