I have the CM15A, AHP v3.228, and the excellent XTB-IIR from Jeff Volp.
The CM15A is in an upstairs room and programmed to turn various lights on and off around the house. The XTB-IIR is downstairs and plugged in through the dryer plug which is about 15 feet from the main circuit panel. TVs and surge suppressors are behind XPPF filters.
The XTBM (Jeff Volp's excellent X10 Monitor) reports 8+ VPP sending signals to downstairs modules and 6+ VPP on upstairs modules when measured from an outlet in the room with the CM15A. Frequency is 120 KHz and Noise measures .00.
Most of the modules are Leviton HCS08-1TW's. In AHP I have the light switches configured as 2-Way Lamp Modules and Preferences|Macros set to "Issue 'On' in place of 'Bright 100%'".
I've had variations of the following for a long time:
Yesterday the CM15A executed all operations right on schedule. Today it didn't run anything. I haven't changed a light bulb nor added any new electronics or chargers. Using a PalmPad lights will turn on and off. If I plug the CM15A USB cable into my computer everything turns on and off manually.
I cleared the CM15A Interface Memory and re-downloaded the timers to it. I'm assuming it will work find now.
As I said, this has been a common theme. My CM15A appears to hold the programming for a while and then loses it. Sometimes in a day, sometimes in a couple of weeks.
Any suggestions of what might be happening?
Thanks,
Greg
