I literally just installed four Caseta dimmers (P-PKG1W-WH), and a smart bridge. Transpired mostly well, but one of the dimmers replaced a 3-way switch that was connected to two 4-way switches and another 3-way switch. I terminated the connections in the other 3-way switch as described in the documentation and put a Pico remote there, but I'm having issues with the two 4-way switches. Capped off a hot red wire with a non live outgoing white, a hot white with a non live red, and the ground separately in each of the two locations. The dimmer works, but I can now hear a buzzing at the circuit breaker box when it's turned on, whereas there was none below when the 4-way switches were present. I then -in each 4-way location- capped off all 4 wires in one connection, and the ground in a separate connection. This works, but the buzzing is still present when I turn on the dimmer (which works in this configuration as well). When the dimmer is turned off, the buzzing at the breaker ceases. At this point, I've turned off that breaker, and hoping someone might be able to guide me in the right direction on how to correctly cap off the wires where the 4-way switches used to reside. I know this information is properly insufficient to troubleshoot, but I'd be happy to answer any questions, and would really appreciate any assistance anyone can offer. TIA.
