Google patents home hub that shares smart home data with other devices

Google describes a system where a central home hub acts as a middleman for smart home data. It receives information from a cloud service, stores it in specific groups called clusters, and sends updates to other devices that have asked to be notified. This allows devices to decide on their own whether to take action based on the new information.

Why it mattersThis could make smart home setups more efficient by letting devices react to shared data without constantly checking the cloud, though it is a standard improvement in how devices talk to each other.

In the filing’s own words

Techniques and devices for sharing intelligence-derived information by a hub in a home network are described in which the hub exposes a virtual device including one or more clusters on the home network and receives from a partner device a request to subscribe to a cluster of the one or more clusters. The hub receives state information from an intelligence service, stores the received state information as an attribute of the cluster, and publishes the attribute of the cluster to the partner device, the publishing being effective to direct the partner device to determine whether to perform a local action based on the attribute. Alternatively, the hub receives, from a partner device, an advertisement of a custom cluster installed at the partner device and provides state information by sending a command to the custom cluster at the partner device, the command being indicative of the received state information.

What exactly they claim (claim 1)

1. A method of sharing intelligence-derived information by a hub in a home network, the method comprising the hub: exposing a virtual device on the home network, the virtual device including one or more clusters; receiving, from a partner device, a request to subscribe to a cluster of the one or more clusters; receiving state information from an intelligence service, the state information associated with the cluster; storing the received state information as an attribute of the cluster; and publishing the attribute of the cluster to the partner device, the publishing being effective to direct the partner device to determine whether to perform a local action based on the attribute.
