A method and an apparatus are presented for monitoring a concentration of a specific halogen in a body of water such as a spa or bathing unit for example. The apparatus comprises a housing in which is positioned an optical absorption analyzer for making first and second measurement of transmission of ultraviolet light from a light source emitting light at a specific wavelength. The second and first measurements are taken respectively before and after the ultraviolet light has travelled through a sample of water and are used to derive a concentration of the specific halogen. The derived concentration may then be communicated to a user using a display device and/or may be used to control operational components of a bathing unit for adjusting the concentration of halogen in the water. In some practical implementations, the apparatus may be embodied as a standalone device, which may be configured to float on the water of the bathing unit or, alternatively, may be configured for being installed in-line in a water circulation path of the bathing input by connecting the housing to circulation piping.

An energy harvesting wind sensor is provided for an awning assembly. The device is self-powering in that energy is converted from wind to electrical in order to power the sensor and a transmitter which signals a receiver to retract the awning assembly if a preselected threshold is met or exceeded. Since the system converts wind energy to electrical energy, wiring is not needed to extend along the moving or rotating parts of the awning assembly.

A safety marker apparatus comprising a hollow body including at least four vertex elements interconnected by flexible resilient rods, the body being adapted to be compressed into a stowed state upon application of an external force and expanded into a deployed state, the flexible resilient rods forcing the hollow body to adopt the deployed state in an absence of the external force. In one embodiment, an illumination sub-system is provided in at least one vertex element.
