I have some 200 insteon devices throughout my property and until today have never had a communication issue. Are there any known issues with having multiple devices together in one wall box? I noticed with three together I can hear the slight buz of communication but in a remodel I installed four in place of standard switches and while I don't hear anything I get flickering LEDs on all four switches when one is used and sometimes one or another of the four will refuse to switch a light on or off. I know I had this issue with z-wave ( minus the flickering) before I switched to Insteon but I always had issues with z-wave not communicating with one device or another.
Any suggestions or ideas would be helpful.
Thanks
