Tnx, for the reply X1-10.
"Crazy" means just about anything at anytime. I'll touch a remote to turn on a light, for example, and the drapes might open. But both the light and drapes will work properly for weeks prior to the error--and nothing has changed. The offending command sometimes shows up in the Activity Monitor, sometimes not.
The only partial consistency to the problem (but not all the time) is that the error often appears on the same house code as the unit I'm trying to activate. (I'm using 10 housecodes--lots of units, sensors, and cameras.) But the Activity Monitor does not show them being selected together--each is a separate command if I see it at all.
This is why I was considering the interface due to the inconsistency.
