A distributed resource model is described that maintains traits of resources in a distributed computing system. The traits include properties, commands, and events that, along with protocols operating in the distributed computing system, provide real-time access to the traits of resources in the distributed computing system, as well as real-time command of controls for the resources. Controllers manage and publish the traits of resources and provide various types of functionality, such as arbitration, complexity management, fan-out of capabilities, coordination, adaptation, and resource proxying.

Distributed resource model

In embodiments of efficient network stack for wireless application protocols, a network stack receives an application-layer message in a first wireless application protocol that includes a source address and a destination address, maps the source address to an Internet Protocol version 6 (IPv6) source address, and maps the destination address to an IPv6 source address. The source node transmits the application-layer message to a destination node in a mesh network using a network stack that implements a second wireless application protocol using the IPv6 source address, and maps the destination address to an IPv6 source address.

Efficient network stack for wireless application protocols

Method and systems for controlling data remotely that includes connecting to a remote device within a fabric of smart devices. The remote device stores data locally. Controlling the data includes remotely controlling the data stored in the remote device from another device connected to the fabric by transmitting a message to the remote device. Moreover, the transmitted message includes a profile identifier that causes a data management entity of the remote device to perform an indicated data management action. Furthermore, the profile identifier identifies a data management profile, and the message includes a command tag that indicates the data management action to be performed.

Data management profile for a fabric network

Systems and methods are provided for efficient communication through a fabric network of devices in a home environment or similar environment. For example, an electronic device may efficiently control communication to balance power and reliability concerns, may efficiently communicate messages to certain preferred networks by analyzing Internet Protocol version 6 (IPv6) packet headers that use an Extended Unique Local Address (EULA), may efficiently communicate software updates and status reports throughout a fabric network, and/or may easily and efficiently join a fabric network.

Efficient communication for devices of a home network

Apparatus, systems, methods, and computer program products are disclosed for providing software updates to client devices. A client device (such as a thermostat) executes software to perform one or more functionalities of the device. Upon receiving an indicating that a software update is available, the device waits to download the software update until pre-download conditions are satisfied. Once the software update is downloaded, the device then waits to install the software update until pre-install conditions are satisfied. If the software update is non-critical and received during an initial installation of the device, the software update may not be installed until after installation of the device is complete. If the device is a thermostat, the device may delay installation of the software update until a controlled HVAC system in inactive. Control of the HVAC system may be disabled during installation of the software update.

Updating control software on a network-connected HVAC controller

Methods and systems facilitate network communications between a wireless network-connected thermostat and a cloud-based management server in a manner that promotes reduced power usage and extended service life of an energy-storage device of the thermostat, while at the same time accomplishing timely data transfer between the thermostat and the cloud-based management server for suitable and time-appropriate control of an HVAC system. The thermostat further comprises powering circuitry configured to: extract electrical power from one or more HVAC control wires in a manner that does not require a 'common' wire; supply electrical power for thermostat operation; recharge the energy-storage device (if needed) using any surplus extracted power; and discharge the energy-storage device to assist in supplying electrical power for thermostat operation during intervals in which the extracted power alone is insufficient for thermostat operation.

Smart-home proxy devices with long-polling

Systems and methods relating to communication within a fabric network are presented. The fabric network includes one or more logical networks that enables devices connected to the fabric to communicate with each other using various profiles known to the devices. A device sending a message may follow a general message format to encode the message so that other devices in the fabric may understand the message regardless of which logical networks the devices are connected to. Within the message format, a payload of data may be included for the receiving device to forward, store, or process the message. The format and the contents of the payload may vary according to a header within the payload that indicates a profile and a message type within the profile. Using the profile and message type, the receiving devices may decode the message to process the message.

Fabric network

A thermostat for controlling an HVAC system in an enclosure may include a passive infrared sensor, an active infrared sensor, and an electronic display having a first mode and a second mode. The thermostat may also include one or more processors programmed to change a setpoint temperature of the thermostat to an energy-saving temperature upon detection of a non-occupancy condition for the enclosure. The processor(s) may detect the non-occupancy condition based at least in part on readings received from the passive infrared sensor. The processor(s) may also be programmed to change the electronic display from the first mode to the second mode upon detection of a person approaching the thermostat. The processor(s) may detect a person approaching the thermostat based at least in part on readings received from the active infrared sensor.

Occupancy-based operating state determinations for sensing or control systems

Methods and systems for conveying locale information for an electronic device includes receiving, from a remote device and via a network interface of at least one network interfaces, a request for active or available locales for the electronic device. Conveying the locale information also includes sending, to the remote device and via the network interface, a message in a locale profile format including a list of available locales. The message includes a version field that indicates a version of schema used to transmit the list of available locales, an active local field that indicates a locale currently being used by the electronic device, and an available locales field that indicates which locales are available for use by the electronic device.

Locale profile for a fabric network

A thermostat includes a plurality of HVAC (heating, ventilation, and air conditioning) wire connectors for receiving a plurality of HVAC control wires corresponding to an HVAC system. The thermostat also includes a thermostat processing and control circuit operative to at least partially control the operation of the HVAC system and a powering circuit coupled to the HVAC wire connectors and configured to provide an electrical load power to the thermostat processing and control circuit. The thermostat includes circuitry and methods for maximizing efficiency of energy harvested from the HVAC system connected to the thermostat, and depending on which system is connected to the thermostat, different power schemes can be implemented in order to obtain power from the HVAC system.

Power management in single circuit HVAC systems and in multiple circuit HVAC systems

This disclosure relates to systems and methods for verifying that a device is using its Wi-Fi circuitry in compliance with the regulations governing the location in which the device is located. Embodiments discussed herein can verify the location using location verification tools that evaluate locally ascertainable factors that contribute to a probability determination of the device's location. Locally ascertainable factors include information that be gleaned from the surroundings of the device. The surroundings or environment in which the device resides may provide clues as to whether the device is located in a particular regulatory domain.

Systems and methods for enforcing wireless regulatory compliance

A thermostat is described that includes a rechargeable battery, a graphical user interface and a wireless network communication capabilities. During installation, in cases where the rechargeable battery is below a first threshold, the installation procedure is limited so as to avoid energy intensive installation steps which may not be supported by the low battery level. An example of an installation step that is avoided due to low battery level is set up of wireless communication. According to some embodiments, if the battery level is very low during initial installation, the installation process is halted while the battery is charged. An indication such as a flashing LED may be displayed so as to indicate to the user that the battery is being charged.
