Smallest cost stand alone device

[Bill Brower]

So for a car pulling up you could go off of that person's cell phone, but what is the least expensive device that you could put into a car, example: cheapo BT earbud, that would still have some range and doesn't rely on that person having their cell phone on.

I don't mind hooking into the car power, I am looking for examples of an inexpensive device you might just leave in that car.

Thanks for the input,
Bill

How about a wireless security system sensor. I am not familiar with current security systems, but I would assume they have some indication if their devices are not reporting; and then when the car comes home the device would start reporting.

Fry's had a BT mouse on sale for around $30 a couple of weeks ago. This kind of device might be an alternative?

There is an excellent How To either on this forum or Cocoontech that speaks to putting a X10 RF motion sensor in car connected to car battery. Then with DooMotion or similar HS plugin, when the car gets in range of the corresponding X10 RF receiver, your leg motion trips the motion sensor and DooMotion registers "Mike is Home" or whatever. Very cheap solution. Put on in each car and reuse the same X10 receiver for both. Plug the receiver into an outlet near the garage.

Don't think bluetooth is the right solution for this problem. too short range and possibly longer handshake time.

Might work for accurate reporting and identifying you once you are pulled into the garage.

Answering the orig question,

I frequently see inexpensive bluetooth devices like headsets on www.bensbargains.net
