## Abstract

An event notification system includes a wireless device, an Access Point device, a server, and a user application. The server is configured to receive a plurality of heartbeats from the wireless device and through the Access Point device, and send a heartbeat response of a plurality of heartbeat responses in response to a respective heartbeat of the plurality of heartbeats. The user application is configured to send enable and disable commands to the server. The enable command is sent to the wireless device as part of the next heartbeat response of the plurality of heartbeat responses. The disable command is sent to the wireless device after the server receives an event condition from the wireless device through the AP device.

## Claims

### Claim 1

An event notification system comprising:
a wireless device including a sensor for detecting an event;
an Access Point (AP) device;
a controller configured to receive a plurality of heartbeats from the wireless device and through the AP device, and send a heartbeat response of a plurality of heartbeat responses to a respective heartbeat of the plurality of heartbeats; and
a user application configured to send sensor enable and disable commands to the controller, wherein the sensor enable command is sent to the wireless device as part of the next heartbeat response of the plurality of heartbeat responses, and the sensor disable command is sent to the wireless device after the controller receives an event condition from the wireless device through the AP device.

### Claim 2 (depends on 1)

The event notification system set forth in claim 1, wherein the event notification system is a security system, the sensor enable command is an arm command, and the sensor disable command is a disarm command.

### Claim 3 (depends on 1)

The event notification system set forth in claim 1, wherein the controller is at least part of a cloud server.

### Claim 4 (depends on 3)

The event notification system set forth in claim 3, wherein the cloud server includes a virtual security panel.

### Claim 5 (depends on 1)

The event notification system set forth in claim 1, wherein the user application is a mobile application.

### Claim 6 (depends on 1)

The event notification system set forth in claim 1, wherein the wireless device is a Power Save Mode (PSM) device.

### Claim 7 (depends on 1)

The event notification system set forth in claim 1, wherein the controller is configured to send a disabled response to the user application in response to receiving the disable command and without sending the disable command to the wireless device via the AP device.

### Claim 8 (depends on 1)

The event notification system set forth in claim 1, wherein the controller is configured to buffer the disable command and suppress the event condition prior to the controller sending the disable command to the wireless device after receipt of the event condition.

### Claim 9 (depends on 8)

The event notification system set forth in claim 8, wherein the controller is configured to buffer the enable command prior to the controller sending the enable command to the wireless device via the next heartbeat response.

### Claim 10 (depends on 1)

The event notification system set forth in claim 1, wherein the wireless device includes a plurality of awake states intervened by a plurality of sleep states, and each heartbeat of the plurality of heartbeats are sent during a respective awake state of the plurality of awake states.

### Claim 11 (depends on 10)

The event notification system set forth in claim 10, wherein the event notification system is a non-beacon-tracking security system.
