Connect mysensors node to existing alarm system.

[Tomasz Pazio]

I have quite old but still working fine alarm system connected to monitoring service.
I would like to monitor states of sensors connected to it, do You think that this is possible just to connect to inputs of alarm system and check logic states via analog ports?

I tapped into a newer alarm systems door sensors by measuring the voltage via the analog pins. My alarm still works, but I can also see open/closed via mysensors/openhab.
