Meet the Switch Bot: a tiny bot that you can attach to any appliance or light switch and control from your smartphone. It automates control of your appliances, so you can use it to turn on your coffeemaker, control your TV, interact with your old thermostat, and do a whole lot more.
Switch Bot has Bluetooth. The Switch-Link unit connects to your home WiFi network. Simply set your preferences for home appliances and let these tiny robots do the rest. IFTTT integration is available. More info is available here.
