## Abstract

A system of controlling one or more building automation devices. The system may incorporate communicating over a first network with one or more network connected devices. An access point for the first network may be utilized to facilitate communication among the network connected devices. One or more of the network connected devices may be a low power device that has a first mode and a second mode. The low power device may expend less energy in one of the first mode and the second than in the other of the first mode and the second mode. The system may allow network devices connected to the first network to receive details about the low power device while the low power device is operating with the first mode and the second mode.

## Claims

### Claim 1

A system for communicating over a network via an access point, the system comprising:
a first device connected to a network and in communication with an access point for the network; and
a second device connected to the network and in communication with the first device,
wherein the second device is a building automation device, wherein a building automation device comprises one or more of: a camera, a carbon monoxide detector, a smoke detector, a light bulb, a building automation sensor and a heating, air conditioning and ventilation (HVAC) controller device, and
wherein the second device is configured to automatically enter and exit a power saving state and, while in the power saving state, not communicate with the first device or the access point; and
wherein:
the first device is configured to:
store one or more details of the second device,
receive periodic state updates from the second device without sending a request for an update to the second device,
update the one or more details based on the periodic updates,
receive multicast packets of data on the network to a plurality of devices connected to the network, wherein the plurality of devices comprises the second device, and
identify multicast packets of data on the network that are directed to the second device.
