I've read through the variious threads re: RF reception problems with DS10As etc. It was so frustrating to see such a potentially versatile ($49, I might add) system hobbled by the RF range issue. I came this >< close to buying Homeseer.
To make a long story short, I'm now receiving DS10A events reliably. I was going to try one of the antenna mods, but first I decided to clean up a bit of the wire clutter around the desk behind which the CM15A is located. Once I did this, all of the open/close events from the DS10A on my freezer door (located in basement below) were received, however, in the past they were also always received after I ran INSTALL in AHP and pushed TEST on the DS10A (i.e. initial RF signal as well as all subsequent ones).
After thinking about it a bit, I realized that the events were always received on the first day (never actually verified this, but I believe this to be true) but none appeared in the log starting the next day. My computer shuts down every night.
If one does a SAVE after the sensor is configured (name, location etc.), but not after the INSTALL, could it be that the hardware ID is only known by AHP until the next reboot since it didn't get saved to disk and only existed in volatile RAM?
