You didn't mention wires. And I think it's worth considering. Most probably your sensor is going to be connected to power plug (if it goes detached). So why not to situate mini-server (RPi-alike) nearby, with a sensor connected by wire?

Not sure I follow. The door sensor is going to be hanging on my daughter's door, and the alarm would be in my room, probably 40 ft away.

Wherever you place the sensor, it most probably needs power supply. Batteries die, so I'd go with plugging into power socket. Since we use a nearby (to daughter's door) power socket, we could insert _right_there_ a mini-PC to control the sensor (because sensor just senses, and you need some "digital brain" to do something with results of sensing). Then mini-PC could notify you in a lot of possible ways.
