Car at Home?

I've talked about it here before, but I'm very happy with my CheaperRFID set up, and I use it to open and close the garage doors, announce arrivals / departures, and update my web page to show what cars are present (hidden from guests).
I installed one of the 12V-powered 40M boxes in each of two cars, and put 2 8M boxes in each of our three cars. They are cheap enough it doesn't hurt my head to have that many, and it makes the reliability pretty outstanding.
Although I announce and update the web as soon as all the tags for a car are out of range (or for arrival, at least one is back in range), in order for a car to be considered "really gone", all the tags had to be out of range for at least 5 minutes. I use this "really gone" for controlling the garage door, to keep the door from going back and forth in the event of a couple of tags dropping out at the same time (which doesn't happen much, may be once or twice a year).

Yeah, the CR2032 batteries last a long time. The only exception is in cold weather. When my truck is parked outside the garage in cold weather, I get a few more dropouts than usual.

Rupp, how do you have the AA's connected? Do you have 4 AA's wired to the 6V unregulated post on the 40M transmitter? I know there is another thread where someone said they tried a 9v on the regulated post and got really poor results (2 weeks).
I have been contemplating my RFID purchase and I keep bouncing back and forth between the one with the cr2032 batteries and the 12v version, although a good battery pack setup would certainly persuade me.

Looking for suggestions. Where would be the best place to position a 40M tag in a car? I've tried the sunglasses compartment above the windshield with no luck. If I just set the tag on the roof of the car in the garage (no I'm not about to glue it there) it works fine. Somewhere near a 12V supply would be ideal.Real courage is not securing your Wi-Fi network.

In my truck, I have it double-stick-taped behind the rearview mirror. In my wife's SUV, it's mounted on the dash in the corner on the passenger side. The third vehicle just has it tucked in the map compartment in the door.HS4Pro on a Raspberry Pi4

A big priority is to keep the tag out of sight. Above the windshield ('07 Nissan Altima BTW) would be my first choice as there's a map light there I could use to supply power to the tag. Routing the antenna seems to be the issue there. Hanging straight down as a test, which I thought would allow it to radiate out the window, didn't work. The only other option at that location is going to be to tuck it up under the windshield which will orient the antenna at 90 degrees to the receiving antenna when the car is parked in the garage, minimizing coverage.Real courage is not securing your Wi-Fi network.

True - mounting mine on the ceiling of the garage was the best move I made. I just ran ~50ft of cat5 back to the serial port and used an external power supply plugged into the garage door outlet in the ceiling.HS4Pro on a Raspberry Pi4

I modified the receiver enclosure and mounted an F-Connector on the end, ran TV cable from the receiver (which stayed by my HS machine in the basement) the 100 feet out to the garage, and connected it to a 1/4-wave "cross" antenna mounted on the ceiling of the garage. I also put a Radio Shack RF amplifier (one that plugs right into the TV-cable) in line. With this set up the 40M transmitters (with no external antenna, just the one coiled up inside the box) gives me close to a quarter mile range in some instances. When my wife is coming home, the garage door is fully open by the time she can even see the house.

Basicly what happens is the slug polls for the name of my bluetoth devices using hcitool name MAC ADDRESS and I pipe it to a file. Then I check to see if the file is empty or not...empty means it wasnt found, something in it means the device is around. If it's not empty I then drop a file on the HS server using smbclient. HS looks every minute to see if there are any files in the drop folder and updates the status accordingly.
The neat thing about using the linux hcitools is that it can tell if ANY bluetooth device is around, even my iPhone....
