I want to equip parts of house with door/window and PIR sensors.
I initially tought that I will use cheap 433mhz sensors that are integrated with RFXCOM into openhab (which is also the sink for my mysensors network).
They are around 3-4$ per sensor. I would then only use mysensors for things like temperature monitoring, some actors, etc.
However, the obvious problem is security. With those cheap 433mhz sensors it is pretty easy to just listen and tell when my basement door or a certain
window is open or not, if someone really wants to (ignoring the chances right now).
Mysensors seems to be more secure here, but I assume that there are limitations regarding encryptions.
How do you see this and how do you do it? Any suggestions appreciated..
