One of my homey challenges is to catch the signals from my alarm system. (Its an older system without smart interface)
Every room in the house has a wireless sensor, would be great if I could use these for presence detection.
I searched for an app that could read the sensors but did not find one. So the challenge is to create one myself (with a little help) have no idea how to start and do not have a lot of software skills…
My sensors are 1way sensors 868.35MHz.
So the interface is probably simple: identifier for the unit & on/off signal.
There could be 2 ways to go:
1 Read the RF signal that is send by the sensor (how?) and build an app that monitors for that signal.
(Trigger a sensor, catch the signal, use that)
2 figure out the the RF coding and build an app around that.
Suggestions on how to start are welcome
(Or maybe I missed an app thet excist)
