If you take a look at this thread, you will see how im monitoring tire pressure with nymea. Im doing this by using a cheap $20 SDR (Software defined radio) and the rtl_433 package to read directly from the tire pressure sensors.
You can monitor so much, so so much more. If i put rtl_433 into monitor mode, it picks up my rf remote for my tivo, the wireless weather station the neighbor has, and a ton of other devices.
Im not that good at “Magic” but i can pretty much say you could setup magic and use any old RF remote control you have laying around to control things in nymea. Very cool! So many devices have been decoded in rtl_433, it gives you a lot of possibilities!
Just giving you guys some ideas! nymea +rtl_433 is a winning combo!
