Abstract: Techniques and devices for administering network-connected devices using tunneled routing are described for accessing administrative services using an access router in a network segment of a fabric network in which a first access router in a first network segment of a fabric network receives a first advertisement for a second network segment of the fabric network and establishes a first secure tunnel with a second access router in the second network segment in the fabric network. The first access router advertises, in the first network segment, a first network route to an Ecosystem Administrative Service, EAS, in the second network segment, and uses the advertised first network route to route messages between one or more devices in the first network segment and the EAS.

Abstract: 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.

Abstract: 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.
