RISCO units

Hello community! Have bought a home with an older FALCK smart home alarm system. The components in the system comprises of door detectors and fire detectors all communicating at 868,65 MHz.

The problem is that FALCK doesnt deliver alarm services anymore and I was hoping not to throw these perfectly fine units away. Anyone know a workaround to make use of these?

RISCO WL T33S is the fire alarms. Have reached out to them about support with the Homey PRO.

I can’t find anything on the protocol that these devices use, so chances are it’s proprietary. Without any specifications, it’s going to be very hard to get them working with Homey (even with specifications you’d still need to find a developer to implement an app, and it depends on Homey even supporting the protocols used).
