Hi there.Every few weeks, but increasingly so, our satellite dimmer/switches just stop responding. Their little LED lights stay on, but they cease functioning otherwise. The only way we can turn lights on or off is to use the main zone panel. I've tried doing the reset thing where you hold down two of the buttons on the main zone panel, but this doesn't seem to solve the issue.Any ideas what could be the problem? Often if one zones in the house becomes unresponsive, all the zones in the house do (but not always I think).Any guidance greatly appreciated, thank you.
