The Smart Plug Bundle I includes the basics- Smart Plug & Smart Plug Remote. The Smart Plug turns your electronics on or off from anywhere using your Smart Plug Remote. The most common use for this product by hard-of-hearing, deaf, or sound-sensitive people is to connect a lamp or other lighting source to the Smart Plug. This allows the lamp to light up if someone pushes the Wireless Doorbell. Make your home a “Smart” home by using these Deaf-Friendly products.
