Was wondering if anyone else is facing this type of scenario with motion sensors controlling a light that may or may not already be on...

I have a shed light which I'd like to control with a motion sensor...
If it's already on, I want to just leave it alone (the light is part of other scenes that might be active).
Otherwise I want to turn it on for 1 minute, then back off.

I tried creating an event like this in houselinc:
Trigger: Motion detected
Conditions: On level of light = Off
Actions: Turn light on. Pause 1 minute. Turn light off.

But, being a wireless device that insists on sending motion sense messages 2 times, events seem to get all screwed up.
The event fires correctly upon the first message.
Upon the second message, the event fails (Condition On level = Off was not successful, b/c the first message/event already turned it on)... and stops processing the first instance of the event.

Am I overcomplicating things by using events at all? is there some workaround anyone would know of to prevent wireless devices from resending the same message twice?

Thanks for any input.

You can accomplish the task using two Insteon devices wired in parallel. One is linked as a responder to the MS, the other is not.

If the device not linked to the MS is on, then the MS will have no effect. If it's off, then the device linked to the MS takes control.

Just trying to wrap my head around this idea... by parallel, you mean connecting 3 total wires together, right? the load wires from both insteon devices, and the power to the light?

Are there any restrictions to this kind of wiring? do both insteon devices need to be on the same phase? can you mix and match devices (relays/dimmers)? any other caveats?

Parallel means the same neutral, line, and load. They are not only on the same leg of the split, single-phase electric supply, they are on the same circuit. Such wiring conforms to the code.

You'll need SwitchLinc or KeypadLinc as the nonlinked load controller and an In-LineLinc or Micro Module as the load controller linked to the MS.

You can mix and match with this caveat: when both devices are on, the device with the brighter setting takes control.

Got it. Thanks, Stu... will probably pick up a micro-module and try this out.
