I have an unused security system in my home(honeywell, was here when I bought it last year) and I don’t have any interest in using it, however I am curious if it’s possible to somehow connect all of the battery powered sensors that are already on my doors and windows to Hassio?
I’ve seen some discussion about connecting the full security system itself, which could be possible, but all I want is to utilize the door/window sensors that are already installed, not the entire system.
Is this possible or are those sensors all proprietary and only connect to the installed system they came with?
