I have an ISY, several Keypad Links, Toggle Links, and plug-in modules. I also continue to use a number of X-10 devices (mostly wall modules). I started experiencing problems when moving from ISY version 2.6.7 to 2.6.13 (or thereabouts), but am considering the possibility that this may be coincidental. Regardless....
In a simple program that turns on a couple of scenes and sends a couple of X-10 commands, everything appears to work based on the adminsitrative console display. After the program is run, all the displayed states are displayed as I would expect (which is 40%) based on the just-executed program. Unfortunately, the physical state of the lamps (which are off) does not match the displayed state (which is 40%). If I run a query on the suspect devices, the displayed state is updated to match the physical state (off).
There have been times when I am suspecting communication issues, and have been trying various combinations of factory resets, relinks, and the moving around of access points, but I can't help but suspect that the mismatch between actual state and that displayed by the ISY-99 admin console is a clue as to my problems. Unfortunately, I am not smart enough to reach any definite conclusions.
Anyone experiencing this problem or have any thoughts?
