I have an archaic Yale alarm system which uses 433.92mhz sensors.
I have already built a security system using HA.
I would like to be able to link HA to the sensors directly so I don’t have to redecorate every place where there are sensors. Its a mixture of PIR and Reed Switch sensors.
Is it possible to do this as from what I understand every company uses different protocols so is there a way of picking up the signals universally which I can use as triggers?
I know you can do it with Infrared remotes but I’m thinking the 433.92 might be really challenging.
Has anyone experience of doing this? What hardware did you use (or do you use)
Many thanks in advance
