I'm relaying an issue my GC said he's having at another client's site. They said they've got an RA2 repeater and a third-party shade controller operating on 433.6Mhz, and the shade controller doesn't work if the RA2 system is plugged in. When they unplug it, things work. I'm surprised the repeater would be sending much traffic when idle, or that there's interference at all given garage door openers operate around this frequency. Is this something others have seen? Anything to be done other than spread them apart?
