Methods, systems, and apparatus, including computer programs encoded on a storage device, for detecting water leaks and mitigating the damage caused by the detected leaks. The system may include a processor and a storage device storing instructions that, when executed by the processor, cause the processor to perform operations. The operations may include obtaining sensor data that is generated by one or more flow rate sensors located at a property, obtaining status data that is generated by one or more connected water shutoff valves located at the property, determining, based on (i) the obtained sensor data and (ii) the obtained status data whether a water leak has been detected at the property, and in response to determining, based on (i) the obtained sensor data and (ii) the obtained status data, that a water leak has been detected at the property, initiating performance of one or more water damage mitigation operations.

A watertight electrical compartment for use in an irrigation device can include a compartment body having a chamber and a sealing section configured to mate with one or more sealing rings. A sealing cap can mate with the sealing section and/or the sealing rings to seal the chamber. A cap retainer can be advanced over at least a portion of the sealing cap. One of the compartment body and cap retainer can have internal threads to be screwed onto external threads of the other one of the compartment body and cap retainer. The cap retainer can also have a stopping feature to keep the sealing cap in its sealed position. The watertight electrical compartment can be used in a wireless flow sensor assembly, a battery operated irrigation controller, and/or a battery-operated central controller device, to provide irrigation control, and/or sensor information, without the need for AC power.

The present invention teaches a solenoid-valve actuator that is battery-powered and communicates remotely and wirelessly (e.g., via LoRaWAN) to a gateway that communicates with the internet, thereby enabling a user to remotely control fluid flow through a solenoid valve. The end device interfaces to a range of latching solenoid operated valves, e.g., for the control of water flow in irrigation systems.

A motor vehicle air-conditioning line valve arrangement includes a line valve having an air-conditioning line body which is of substantially closed design in a transverse plane, and a fiber nonwoven arranged on an inside in the air-conditioning line body and having a nonwoven mat to which a large number of nonwoven fibers are fixed. The nonwoven fibers are fixed to the nonwoven mat at one end and configured to be electrostatically charged by the nonwoven mat. An electrical charge generator is electrically connected to the nonwoven mat and configured to electrostatically charge the fiber nonwoven, so that the electrostatically charged nonwoven fibers straighten toward a center of the air-conditioning line body in such a way that they close an open flow cross section of the air-conditioning line body.
