I have a similar problem. I use motion sensors to trigger my Nightwatch cameras with a side macro for activating lights to help with the illumination. Sometimes, the system works. Other times, not so much. When I check the activity log, I see that the RF was received from the motion sensor, but that no macro was sent back out. I know the macros work, because every once in a while, they fire off as advertised and I capture images. I can also trigger them manually and they work fine. I use the motion sensor to activate a phantom switch, and the recording and lights are separate macros triggered off said switch.
I realize there are line noise, phase issues, and a plethora of X10 issues, but here's my thread-related question:
If Activehome's activity log registers the incoming RF signal, is it possible the signal is still too weak to trigger the macro? By extension, if the RF makes it to the PC, should it be strong enough to work? If so, could anyone suggest why my macros don't fire regularly?
I've contacted a trusted electrician and hope to procure a phase coupler in a day or two, but in the meanwhile I am giving up on the security cam setup and installing my door/motion sensors for the security system instead. At least I know THAT will work...
