At the beginning of my UPB implementation migration I installed an SA (one with three leds) passive coupler into the panel. All appeared fine with signal levels between 50-100 on the same phase switches and between 10-20 on the opposite phase switches.
Last night noticed one of the switches didn't shut off according to schedule. I looked at the communications and noticed noise and no communications on the opposite not connected phase switches. This is the first time I've noticed any noise.
I don't understand where the noise is coming from as I have changed/added appliances/devices to the outlets since installation; only more UPB switches.
I have the passive coupler installed on two autonomous breakers at the bottom of the panel. I've seen where folks have added second couplers; would this work for me? Should I move the connections to the top of the panel? Should I try an HAI passive coupler or a PCS passive coupler?
