If any of you don't have an X10 compatible
security system, you can ignore this post.
The security system is X10, model DS700.
After the last few updates my RF range was
slowly going to crap (remotes & PE's).
Also, the v3.186 update my security sensors
stopped communicating.
So, I changed the security House code to a
separate house code. Then changed settings
in the hardware interface configuration.
The transceived house code was on auto. I
put it on specific and selected the letters
I used for my home automation, not!!!! the
security system.
Now everything has been more stable. Hope
this helps.
