If you already own a Nest device, be it the Learning Thermostat ($218+) or a Cam Indoor ($159), the Nest Secure is a great way to build out your smart home. It’s the company’s first smart security system and utilizes the same app as your other Nest devices. The starter kit — consisting of one Nest Guard (a smart hub), two Nest Detects (magnetic door or window sensors) and two Nest Tag (smart keys) — normally goes for $500. For a limited time, eBay is offering 20-percent off this starter kit. That’s $100 off.
Note: You can purchase individual Nest Detect and Nest Tag devices to add to your system later on.
