Abstract

A system involves a plurality of RF-enabled occupancy detectors. Each occupancy detector communicates with and controls an associated plurality of RF-enabled fluorescent lamp starter units. A network master has an RF transceiver used to communicate with the occupancy detectors using a first protocol, thereby retrieving status information from the starter units. The network master also has a second RF transceiver for communicating directly with a cellular telephone using a second protocol. A user can use the cellular telephone to control and interact with the lighting system through the network master, and/or to retrieve status information from the network master. The network master automatically generates and sends email alerts to the user by sending the alerts to an email server. The email server forwards the emails to the cellular telephone via a cellular telephone network. Alerts may, for example, indicate a low battery voltage condition or that a lamp needs replacement.

Claims

1. A method comprising:

running a lighting control program as an app on a cellular telephone;

displaying an image of a lighting environment on a screen of the cellular telephone;

transmitting a TCP/IP packet from the cellular telephone to a lighting network master over a first wireless transmission, wherein the TCP/IP packet includes a command for a fluorescent lamp starter unit; and

displaying information on the screen indicative of the command having been executed.

2. The method of claim 1, wherein the command is to turn on a fluorescent lamp to which the fluorescent lamp starter unit is attached.

3. The method of claim 2, wherein the information displayed on the screen indicates that the fluorescent lamp starter unit has turned on a fluorescent lamp.

4. The method of claim 1, wherein the command is to report back the status of the fluorescent lamp starter unit.

5. The method of claim 1, further comprising:

transmitting the command from the lighting network master to an occupancy detector over a second wireless transmission; and

transmitting the command from the occupancy detector to the fluorescent lamp starter unit over a third wireless transmission.

6. The method of claim 1, wherein the first wireless transmission is a WiFi transmission.

7. The method of claim 5, wherein second wireless transmission is an FSK time-hopping transmission.

8. The method of claim 5, wherein the third wireless transmission is a synchronous beacon transmitted during a time slot.

9. The method of claim 1, wherein the command is addressed to the fluorescent lamp starter unit, and wherein the command is received by other fluorescent lamp starter units and is ignored by those other fluorescent lamp starter units.

10. A method comprising:

running a lighting control program as an app on a cellular telephone;

displaying an image of a lighting environment on a screen of the cellular telephone;

transmitting a command from the cellular telephone to a lighting network master over a WiFi transmission, wherein the lighting network master stores information relating to a fluorescent lamp starter unit;

receiving the information from the lighting network master in response to the lighting network master executing the command; and

displaying the information on the screen.

11. The method of claim 10, wherein the information indicates whether a fluourescent lamp to which the fluorescent lamp starter unit is attached should be replaced.

12. The method of claim 10, wherein the information relates to a fluourescent lamp to which the fluorescent lamp starter unit is attached, and wherein the information is taken from the group consisting of:

a total amount of time that the fluorescent lamp has been on, a total amount of power that the fluorescent lamp has consumed, a period of an average day during which the fluorescent lamp was controlled to be on, and a maximum number of ignition attempts that have been required to ignite the fluorescent lamp.

13. The method of claim 10, wherein the command is included in a TCP/IP packet transmitted over the WiFi transmission.

14. The method of claim 10, wherein the fluorescent lamp starter unit is replaceably attached to a fluorescent lamp.

15. The method of claim 10, wherein the displaying the image of the lighting environment involves displaying an icon representing the fluorescent lamp starter unit, and wherein the icon is displayed on the screen in a top-down schematic diagram of rooms in a building.

16. A device comprising:

a memory;

a first transceiver that receives a first wireless transmission from an occupancy detector, wherein status information received from the occupancy detector via the first wireless transmission is stored in the memory, and wherein the first wireless transmission received from the occupancy detector is communicated in accordance with a first wireless communication protocol; and

a second transceiver that transmits a second wireless transmission directly to a cellular telephone, wherein the second wireless transmission includes the status information, and wherein the second wireless transmission transmitted is communicated in accordance with a second wireless communication protocol.

17. The device of claim 16, wherein the second wireless communication protocol is not a cellular telephone protocol used to communicate voice information from the cellular telephone to any cellular telephone network.

18. The device of claim 16, wherein the status information indicates a low battery voltage condition of the occupancy detector.

19. The device of claim 16, wherein the status information is received by the occupancy detector from a fluorescent lamp starter unit that is attached to a fluorescent lamp, and wherein the status information is taken from the group consisting of:

whether the fluorescent lamp is on, a total amount of time that the fluorescent lamp has been on, a total amount of power that the fluorescent lamp has consumed, a period of an average day during which the fluorescent lamp was on, and a maximum number of ignition attempts that have been required to ignite the fluorescent lamp.

20. The device of claim 16, wherein the second wireless communication protocol is an 802.11 WiFi protocol.
