I currently have a really small openHAB 2 installation, with just a couple of power switches and a Fibaro multisensor, running on a RPi3.
In my house I also have an old installation of an alarm system, with four wired motion sensors placed at good covering positions.
Would it be possible to use these with my RPi and openHAB? Anyone here that have done the same?
I realize that I haven’t told you the exact specs for the sensors (I don’t know yet), but maybe someone have done it before, or possibly someone know for a fact that it would require more money/work than just buying a couple of more multisensors for about €50 each?
