Abstract
The Ohmni-Switch is a system that enables a person to use an existing wall switch/receptacle circuit to control outlets that are not wired in that existing wall switch/receptacle circuit. The transmitter and receiver circuits will be housed in a sealed plastic case. All external surfaces of the devices will not have any contact with the house 120 VAC mains.
Claims1
A system for allowing use of an existing wall switch and receptacle for powering an electrical device, comprising:
- a plurality of Ohmni switch transmitters, each configured to communicate at 2.4 Ghz and use 79 communication channels;
- an existing electrical receptacle to accept an Ohmni switch transmitter, wherein the existing electrical receptacle has a wall switch electrically connected thereto;
- a plurality of Ohmni switch receivers each having a microcontroller, a low power wireless RF receiver module, a relay communicatively coupled to the microcontroller and an outlet to accept a plug from an electrical device;
- wherein each Ohmni switch receiver is configured to be plugged into any electrical receptacle except for the existing electrical receptacle, and
- each Ohmni switch receiver has different RF channels for a user to select from that communicatively pair an Ohmni switch receiver to a desired Ohmni switch transmitter;
- wherein the wall switch provides power to the Ohmni switch transmitter that is plugged into the existing electrical receptacle;
- wherein once powered the Ohmni switch transmitter transmits an RF command signal to a paired Ohmni switch receiver;
- and
- wherein the RF command is received by the microcontroller and is used to switch the relay open to provide power to the electrical device plugged into the outlet.
