Digital timers are a very useful in your quest to save money on your energy bill. You can program them to turn devices on and off. More advanced ones allow you to setup different times for different days. Most electric utilities have the lowest rates between midnight and 7 AM, use a timer to schedule appliances or pool filtering during those hours. Intermatic makes a lot of these timers.
We use this outlet plug timer to control our Internet connection. It is set to turn on at 7 AM in the morning and off at 10 PM at night, seven days a week. The Cablemodem / DSL modem, ATT Microcell, Ethernet switch, and Wireless router are controlled by the timer.
We found powering on/off these boxes far too tedious. Many an evening we would forget to power things down. Installing a timer like this make it automatic.
You are saving energy and increasing Internet security. Leaving your connect on 24/7, invites hackers to probe you.
A cheap analog timer that is GE branded but made by Jasco is available from Home Depot too. It draws a low 0.07 Amps when plugged in. The timer has 15 A rating.
