This is an odd situation for me. When I originally implemented the RadioRA 2 system at a clients house (one year ago) all tested and configuration was fine (client only had one electrical panel). Just recently the client had an electrician come out to install a sub-panel in his backyard, and now the client says ALL lights connected to a switch/dimmer/keypad I installed are flickering. His electrician obviously is going to say it's something with the switches, so I was hoping if anyone has any thoughts to why this would happen AFTER a new sub-panel was implemented.I am already scheduling to go back and check for loose connections.Switches & Dimmers used: RRD-8ANS, RRD-HN4S, RRD-HN3S, RD-RD, RRD-10D, and one PJ2-4B (Pico)Thanks in Advance for your thoughts and suggestions.
