A timer executes a macro which turns on a living room light, delays, then switches a dummy on. The dummy triggers a second macro turning on entry lights. If I'm not home, all lights are on. If I am home, I turn off the living room light, and the second will not execute, relying on a condition that the living room light is on. It has worked for years. Now, the first executes, turns on the living room, then executes the second, but the first executes again (for no known reason) and seems to shut it all down. I've unplugged the interface and removed the batteries, downloaded a second time, but it doesn't help. Can anyone explain. Thanks, Jeff
