Better X10 Motion detector anyone?

A Hawkeye sends a device ON code whenever it senses motion, checking every few seconds it seems. It will keep sending ON codes as long as motion keeps happening within it's range.

I want a motion detector that will send an ON code the FIRST time it senses motion, but not send another ON code unless it has since sent an OFF code (because of no motion for 1 minute). I want to use a motion detector to activate an X-10 close contact module to initiate an IR macro that turns on my VCR, powers on a camera, and starts recording what the camera sees to the VCR. The hawkeye, however, keeps resending an ON code which keeps resending my IR macro so long as there is continuing motion detected.

Do any of you know of a smarter X10 motion detector that sends only one ON code after an OFF state?

You can use any motion sensor with a X-10 XPT2 or XPT3. These are X-10 devices that have connections that allow contacts to trigger X-10 signals. These can be used to sense the trigger from a motion sensor, trigger from a pressure sensor, door contact, light sensor or any thing else you want to use. These allow you to use much better motion sensors. Also, being that you are sending a direct X-10 signal, there is not as much of a delay. The only problem is they are wired, not wireless.

The other option is to program your “PIP/RECORD THE THIEF AT THE DOOR” macro to have a command that will disable the RF transceiver that receiver the motion sensor for a preset time, say 2 minutes. This way the motion sensor can’t send a X-10 signal until the RF transceiver is back on, 2 minutes later. I do this in my house using an appliance module on the RF transceiver. I start the macro with a “DISABLER ON” which turns the appliance module off. Two minutes later the macro sends a “DISABLER OFF” which turns the appliance module back on. I also send out a few “DISABLER OFF” commands through the day to insure the appliance module is in the correct mode at all times (on). (You know how X-10 is… 95%). If your program doesn’t allow a delay in the macro, you could use the motion sensors “OFF” command to issue the “DISABLER OFF”, which turns the appliance module back on. It works great. I have a Sony TV and the PIP commands, when reissued, would make the PIP smaller, smaller, smaller then large … this solved the problem and would surely work in your case.

I don't know of a X-10 motion sensor that does not reissue on commands. The outdoor one (not the eagle eye) will only activate every 30-40 seconds instead of every 10 seconds.

Thanks, Chris.

I think I may have figured out on my own a similar solution to yours.

To start with, I've modified a Cinema6 to allow both it's macro IR buttons to be activated by connections to two seperate Close Contact modules.

The EagleEye (or hawkeye) is set to send a B2-ON whenever it senses motion on the porch. It sends a B2-OFF when motion has stopped for a minute.

I plugged the two Universal Modules (B4 and B5)into an extension cord plugged into an appliance module set to C1.

To "arm" recording the appliance module(C1) is turned ON.

I created two macros on my activehome computer transceiver:

1) When a B2-ON is received from the hawkeye a macro sends B4-ON, causing the Universal module to active macro1 on the Cinema6 which starts recording and/or switches PIP on. This macro then turns C1-OFF. Now the modules are inactive no matter how many times the hawkeye sends ON commands.

2) When a B2-OFF is received a macro sends C1-ON, then sends B5-ON, which activates macro2 on the Cinema6 stopping recording/PIP. Since C1 is on, the system is armed and ready for the next activity on the porch.

Seems to work.

Cool Deal! Glad to see you got it working!
