Has someone in your life ever yelled at you for leaving the lights on? Despite the shift to LED lights, it's still a good idea to turn things off because, while one light might only cost about a dollar a month to run 24/7/365 (here, I'm assuming it's a 6-watt bulb and your electricity costs $0.20 per kWh), think about how many light bulbs you have at home. It soon adds up.

But sometimes, something that you leave on might draw a lot more power than you think, and if it's a pain to turn on and off, or if it looks like it's not doing much when it's in standby mode, people are going to be tempted to leave it on.

What you need is a SwitchBot Relay 1PM switch. This is a palm-sized Bluetooth- and Wi-Fi-controlled switch that you can use to automate switches and lights, and make your dumb home appliances a lot smarter. Don't let its tiny size -- it measures 1.6 x 1.4 x 0.6 inches and weighs just 0.9 oz -- fool you. There's a lot of cool stuff packed into this package.
