Abstract: A circuit interface includes a plurality of inputs, an internal controller, and a communication module. Each of the inputs may be configured to connect to a respective high voltage relay output of a pool and/or spa control (“PSC”) panel. The internal controller may be connected to the plurality of inputs, and together, the internal controller and the plurality of inputs can be configured to convert relay output signals into formatted data that includes an implementation protocol. The communication module can be configured to transmit the formatted data from the circuit interface. Conversions from the relay output signals to the formatted data can include specifying or configuring the formatted data to cause a device controller to operate devices corresponding to respective PSC panel relay outputs by directing individual low voltage supplies from a common low voltage source to the respective devices.

Abstract: Systems and methods for operating lights can include stepping down a high voltage power supply and transmitting a resulting low voltage through a relay to a light. A device controller system can receive a selected mode for operating the light including a setting for brightness, color, or operation scheme. The selected mode can be converted into a command configured to cause the light to operate continuously while changing from a current mode of operation to the selected mode. The system can determine an operation sequence for the relay to convey the command to the light. A schedule for the operation sequence can include a zero cross operation by the relay indicating, to the light, the setting or an operation mode change. The relay can operate according to the operation sequence and the schedule and the light can change to from the current mode to the selected mode without delay.
