Methods and systems described herein provide control of a lighting system, such as a pool lighting system. The pool lighting system includes an integrated control device that includes both a transformer and a controller. Lighting devices are powered by power from the transformer using power lines and controlled using power line communication (PLC) signals sent over the same power lines.

Lighting system control using integrated control device especially useful for lights of swimming pools and spas

A sensor system for swimming pools and spas is detailed herein. The sensor system can include one or more sensors positioned in a sensor housing located within a cavity of a pipe and in-line with an inlet and an outlet of the pipe. The sensor housing can divert a portion of water flowing through the cavity to an interior of the sensor housing and to an area around the sensors and maintain at least some of the diverted water in the area around the sensors even if the water is not flowing through or is drained from the pipe.

Plumbed in-line sensor system for swimming pools and spas

Chlorinators with multiple spaced gas traps and flow sensors are detailed. The sensors also may be protected, at least somewhat, from contact with scale build ups by interposition of a mechanical barrier. Ramps or other geometric restrictions may be used to increase water flow to some or all of the gas traps. Additionally, the chlorinator housing may be configured so as to route, or focus, gases toward a small-sized, high point thereof.

Chlorination systems

Equipment and methods facilitating suitable orientation of salt-water chlorinators (SWCs) relative to the gravitational field of the Earth are detailed. So orienting an SWC in this manner reduces risk that the volume defined by its gas trap would not be accessible to hydrogen gas generated by the SWC in use. An accelerometer may be employed in connection with the SWC to assist in assessing orientation of the SWC relative to the gravitational field of the Earth.
