Lately a number of my Insteon devices will not react to commands. I have to activate them numerous times before the lights go on or off. I'm wondering if restoring the PLM would help? All my devices are powered, so I assume i just hit restore and see what happens. If this isn't the problem, do you have any idea what should try. I do have a Insteon Extender in the line and it shows sold green. I have tried to move it, but that didn't help.
