The Plum lightpad lets control your home lighting without the need for any additional hardware, gateway or bridge. It's a smart dimmer that's designed to fit any North American light switch receptacle with no modifications. Simply remove your current switch and wire in the lightpad with just four wires. The lightpad contains an high performance processor, open source API, an advanced operating system, and a full IP stack. It uses the same Wi-Fi security as the other devices on your home network including WEP, WPA and WPA2. Any information that is sent between the Plum app, the lightpad and your cloud service is securely encrypted. There's an energy meter inside every Plum lightpad, smart plug and smart outlet. The Plum app allows you to track and monitor everything attached to a Plum product. So, you can find out how much it costs when you leave your porch light on all night, track which appliance takes the most energy and learn other important energy info that can save you money and reduce your electricity usage.
