## Abstract

Example embodiments relate to a node and a method of controlling devices connected to the node. In example embodiments the devices may be, but are not required to be, lights.

## Claims

### Claim 1

A node comprising:
a microprocessor configured to control a powered device based on data received from a controller and, in the event the node does not receive expected data, control the powered device independent of the controller, wherein the node includes an electronic database for storing at least one control parameter, wherein the at least one control parameter includes a time value, wherein the microprocessor is configured to control the powered device independent of the controller after the microprocessor fails to receive the expected data for more than the time value.

### Claim 2 (depends on 1)

The node of claim 1, wherein the node includes a port configured to interface with an Ethernet cable.

### Claim 3 (depends on 1)

The node of claim 1, wherein the at least one control parameter further includes a dim value.

### Claim 4 (depends on 3)

The node of claim 3, wherein the powered device is a light.

### Claim 5 (depends on 4)

The node of claim 4, wherein the microprocessor is configured to control the light independent of the controller after the microprocessor fails to receive the expected data for more than the time value and control the light based on the dim value.

### Claim 6 (depends on 5)

The node of claim 5 wherein the expected data is generated by a data generator arranged remote from the node.

### Claim 7 (depends on 1)

A system comprising:
the node of claim 1;
the controller; and
the powered device.

### Claim 8 (depends on 7)

The system of claim 7, wherein the node includes a port configured to interface with an Ethernet cable.

### Claim 9 (depends on 7)

The system of claim 7, wherein the at least one control parameter further includes a dim value.

### Claim 10 (depends on 9)

The system of claim 9, wherein the powered device is a light.

### Claim 11 (depends on 10)

The system of claim 10, wherein the microprocessor is configured to control the light independent of the controller after the microprocessor fails to receive expected data for more than the time value and control the light based on the dim value.

### Claim 12 (depends on 11)

The system of claim 11, further comprising:
a second node configured to generate expected data.

### Claim 13 (depends on 12)

The system of claim 12, wherein the second node is configured to periodically send the expected data to the controller.

### Claim 14 (depends on 13)

The system of claim 13, wherein the second node is connected to a network switch.

### Claim 15 (depends on 7)

The system of claim 7, wherein the node includes a switch for routing power from a battery to the powered device in the event the node does not receive the expected data.
