Systems and methods of (remotely) controlling aspects of pools and spas and of modifying water contained therein are detailed. Internet-enabled access to pool and spa controllers may happen without any need for users to create firewall ports or utilize static internet protocol addresses. Certain networking devices may be configured using a USB connection or SD card, avoiding any requirement for an Ethernet cable or supplying separate power to the devices during configuration. Time-varying data may be obtained in respect of one or more installations and analyzed for various information.

Embodiments of the present technology may include a system for tracking and monitoring, including a fastener, a triggering mechanism coupled to the fastener for reacting to physical movement of the fastener resulting from tampering, destruction, or uncoupling; a generator; a tracker coupled to the fastener, wherein the tracker determines a triggered event, and wherein the tracker switches to a low power mode based on an event.

A device. At least some example embodiments are a device including a filter element configured to receive optical energy from a first optical fiber. The filter element is reflective in a preselected band of optical wavelengths. A first lens is configured to receive optical energy transmitted through the filter element. A shell is disposed about the optical filter and the first lens; surfaces of the first lens, the filter element and the shell form a first boundary portion of an internal volume of an interior of the shell. A fluid is sealably disposed within the internal volume.

Disclosed herein is a telemetric fitting for a liquid-level gauge, the telemetric fitting being configured to derive liquid-level information from the liquid-level gauge when attached thereto and wirelessly transmit at radio frequencies the liquid-level information.
