Smarthome (bottom of page) has some options for detection only to be triggered by the car...
Yeah. In addition to being expensive, an inductance coil approach just wouldn't work for my application. I currently have a push button switch hanging from the ceiling of my garage as a test. (It really looks tacky.) I want to place the tape / ribbon switch so that I drive over it creating a momentary on. This will start things in motion. When I drive in it will trigger my welcome macro and when I drive out it will trigger the exit macro. My welcome macro turns on a key indoor light for me, triggers the hot water cycling pump to circulate warm the water to the end of the house and later turns off the garage light. My exit macro shuts down the lights, turns off the coffee pot and closes the garage door a minute after I exit.
I hope I don't have to order the switch from England. They don't bother to quote a price and that scares me a bit too.
The great part is that the macros are working!
Well I do have one bug and that is that one light at the end of the house keeps coming on with the welcome macro in spite of no command in the macro for that switch. Also the activity monitor shows no signal is being sent for the switch code. Maybe the switch is acting weird. I think I'll try changing the code for the next room to the same code as my mystery wall switch and see if it comes on. I think I'll be more surprised if it comes on than if it doesn't. Sounds like a project for tomorrow.
