Introduction

Moore’s law has increased the processing power of computers year after year. As a result, microprocessors have decreased in size and dropped in prices. It is not surprising then that these smaller cheaper microprocessors are finding their way into appliances such as refrigerators, microwaves, ovens, thermostats, washing machines, and coffee makers. All these appliances are starting to incorporate networking circuitry to allow them to connect to the internet. Limitless applications exist such as downloading receipts, turning appliances on/off remotely, and checking the contents of your fridge while you’re at the grocery store.

How to Network

Most of us probably don’t have any networking inputs near our refrigerators, ovens, washing machines, and other appliances. The question then quickly arises, how are we going to connect all these smart appliances to our Home Theater Network? See the diagrams below to help answer this question.

Be weary of companies that use proprietary networking standards that force you to buy all of your appliances from their company. Also, be weary of companies that require you to buy a central appliance (for example, a fridge) in order for other appliances to communicate. In any case, proprietary software will more than likely be required to control your smart appliance through the internet.

Why Have Networked Appliances?
