Publication number: 20240281262Abstract: Disclosed are systems and methods that provide a novel framework for programmatically modifying device capabilities of devices within a location-monitoring system to create unique, specifically configured host-client device connections to effectuate monitoring of the location. The disclosed framework can effectuate modifications of devices to alter their type of device operational capabilities—a host device can be configured to operate as a client and/or a host-proxy for another host, and a client device and be configured to operate as a host, and the like. The disclosed framework enables devices to be programmed such that non-native capabilities are provided to devices that modify how they operate within a monitoring system, as well as how they interact with other devices within such system.Type: ApplicationFiled: February 6, 2024Publication date: August 22, 2024Applicant: Ademco Inc.Inventor: Steven C.

Patent number: 10863322Abstract: A system that implements wireless communication with replay protection for lower power building control applications. In one example, a battery-powered device includes a counter value with each message transmitted to an always-on device. If the always-on device receive an invalid counter value, instead of sending back an acknowledgement, it sends back a message containing an updated counter value. The battery-powered device may keep its receiver on after sending a message for at least a period of time, the battery-powered device receives the message and updates its counter with the received updated counter value. Since it did not receive an acknowledgement, it retries its original message, this time with the updated counter value. The retry message is likely to be successfully transmitted.Type: GrantFiled: August 13, 2018Date of Patent: December 8, 2020Assignee: Ademco Inc.Inventor: Steven C. Nichols

Patent number: 10768589Abstract: A building automation system may adjust operation of a building system based upon information regarding the relative location of one or more users of the building automation system. In some embodiments, a mobile device having location services for determining a location of the mobile device may provide this information. A mobile device may include a user interface, a memory for storing two or more predetermined geo-fences each defining a different sized region about a home of a user of the mobile device and a controller operatively coupled to user interface and the memory, the controller configured to accept a selection of one of the two or more predetermined geo-fences via the user interface. The controller may report when the location of the mobile device crosses the selected one of the two or more predetermined geo-fences to a remote device. Other geofencing approaches are also described.Type: GrantFiled: December 27, 2019Date of Patent: September 8, 2020Assignee: Ademco Inc.Inventors: David Quam, Kevin Weirich, Aaron Klein, Gabriel Bergman, Christopher Goh, Jonathan Frenz, Riley Gerszewski, Rudolph Gamberini, Steven C.

Patent number: 10190788Abstract: An auto changeover mechanism for a thermostat. A heat and cool mode auto changeover with single or crossed setpoints may be an approach for doing a single setpoint auto changeover, an approach that can handle auto changeover with separate heat and cool setpoints that do not require the cool setpoint to always be higher than the heat setpoint, and also an approach that does not necessarily require a dead band between the setpoints. A hysteresis may be associated with switching to the other mode. The thermostat having the auto changeover mechanism may have a display of a mode that automatically changes between heat and cool.Type: GrantFiled: July 14, 2016Date of Patent: January 29, 2019Assignee: Honeywell International Inc.Inventors: Robert J.
