I have an alarmsytem that is using 868.65 MHz.  
The alarm cannot connect to homey. But can homey read the sensors?

The sensors are One-way and has its own unique code, but they always send the same code.  
So if I can record that code, maybe I can write an app to read those sensors.  
All rooms have motion sensors, dont want to put 2 sensors (a second one that supports homey)

- How can I find out if home can receive the signals?
- And if homey can receive them, would it be possible to create my own app to use these signals?

I tried [this](https://tools.developer.homey.app/tools/signals) but it does not seem to work
