On the Network screen, there is a button All On / Off (or something like that). How do I access this from a ISY program? I would like to tell everything to turn off in the morning when I leave and then turn back on just a few things.

 

Thanks!

I use a statement in a program:

 

set scene "my lighting" off

 

(or something close to that). This appears to turn off all insteon devices. It has no affect on X-10 that I can tell.

That was exactly it. I had never noticed that there was a scene "My Lighting" that had appeared without my actually creating it.

 

Now that I have tried it, have observed an interesting effect; about 2/3 of my Insteon devices respond to it on the first try and the remainder on the second try. Anyone have an explanation for why this would be the case?

When I have intermittent problems and less-than-full scene response, I can usually trace that to communication issues. Powerline noise or "signal suckers". Communication problems can slow down responses and force rebroadcasts. I think these can result in signal collisions and the like.

 

It may be possible to mitigate this problem. You could create an "all device" shutdown program, and send off commands to all devices, inserting short (a second or two) waits between each. This may work better.

 

The best best is to test for communication quality (under tools, scene test) and identify and remove (or filter) and problem devices in your house.
