FIG. 37 illustrates a system of LED drivers that can wirelessly interface with users 3714 and utilities 3716, via a gateway 3710 and the internet 3712. Each LED driver 3702 can include a bus connecting a directional RFID sensor 3704 to the LED driver 3702. The directional RFID sensor 3704 of each LED driver 3702 can be oriented to cover a large area or volume of a room or space without much or any overlap between the fields of the sensors. In this way, one, and possibly a few sensors 3704 can detect an active or passive RFID tag 3712 on an object 3710 (e.g., a wheelchair, laptop, mobile phone, etc.) and provide a rough location of the object 3710 to a user 3714 via the gateway 3710. Where multiple sensors 3704 detect the RFID tag 3712, the data can be passed to a server 3713 via the gateway 3710 and the Internet 3712, and the server 3713 can compare signal strengths from the different sensors 3704 and thereby determine a rough location of the object 3710. This rough location can then be passed to the user 3714.
