I have my ISY99 connected to my Elk M1G, which has a W800 wireless receiver connected to it. The W800 allows the Elk to make use of many X10 wireless motion sensors (the common Hawkeyes / Eagleyes) around the property. This works well EXCEPT when a sensor starts to lose battery power, has to have the batteries changed, or starts to otherwise go "bad". When this happens, which can be several times each year with many sensors in use, an X10 signal of A1 is transmitted. On the ISY, this corresponds to the "My Lighting" function, which controls ALL devices in the system. Thus, everything in the system turns on when this signal is received, and it's creating a big problem.
I have tried clearing everything out of the Elk's position A1, and that didn't work. Then, I tried editing the XML export file generated by the ISY, removing the My Lighting group, before uploading the file to the Elk. That doesn't seem to work, either. If an A1 signal is transmitted anywhere on my property, all the lights come on!
Is there anything that can be done to have these three devices coexist? The combination is fantastic as long as a sensor doesn't start to lose power, but that's just not realistic. Any ideas on how to resolve this?
