## 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:
an electronic memory configured to store at least one of a dim value and a script; and
a microprocessor configured to control a powered device based on data received from a controller, wherein if the node does not receive a communication from the controller within a predetermined time limit, the microprocessor independently controls the powered device by at least one of executing the script and controlling the powered device to have a dim level based on the dim 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 an electronic database stores a time value upon which the time limit is based.

### Claim 4 (depends on 1)

The node of claim 1, 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 data communication between the controller and the microprocessor is interrupted 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 controller going offline is the event when data communication between the controller and the microprocessor is interrupted.

### 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 node includes an electronic database for storing at least one control parameter.

### Claim 10 (depends on 9)

The system of claim 9, wherein the at least one control parameter includes a time value.

### Claim 11 (depends on 10)

The system of claim 10, wherein the powered device is a light.

### Claim 12 (depends on 11)

The system of claim 11, wherein the microprocessor is configured to control the light independent of the controller after the data communication between the controller and the microprocessor is interrupted for more than the time value and control the light based on the dim value.

### Claim 13 (depends on 12)

The system of claim 12, wherein the controller going offline is the event when data communication between the controller and the microprocessor is interrupted.
