Publication number: 20230292423Abstract: A multiple location load control system comprises a main device and remote devices, which do not require neutral connections, but allow for visual and audible feedback at the main device and the remote devices. The main device and the remote devices are adapted to be coupled together via an accessory wiring. The main device can be wired on the line side and the load side of the load control system. The main device is configured to enable a charging path to allow the remote devices to charge power supplies through the accessory wiring during a first time period of a half cycle of the AC power source. The main device and the remote devices are configured to communicate with each other via the accessory wiring during a second time period of the half cycle, for example, by actively pulling-up and actively pulling-down the accessory wiring to communicate using tri-state logic.Type: ApplicationFiled: May 17, 2023Publication date: September 14, 2023Applicant: Lutron Technology Company LLCInventors: Ehsan Dadashnialehi, Robert C. Newman, JR., Daniel Curtis Raneri, Jaykrishna A. Shukla
