Weave. Connected home products aren't like mobile phones. Each one takes a different shape to solve a different problem. And when you look inside, you'll find the hardware capabilities of the CPU, RAM, power and radios vary just as dramatically.
Built by Nest. For thoughtful things.
To make great products that are as fast and dependable as our traditional wired homes, Nest needed a secure, reliable communications protocol that works with a wide range of hardware.
Weave in action.Nest Guard, the powered keypad at the heart of the Nest Secure alarm system, is always on. Nest Detect, the tiny, battery-powered sensors of the system, conserve energy by only waking up when there's activity. Using Weave over a Thread network, Nest Detect sensors can talk to Nest Guard when a door or window opens or motion is detected.
Nest Guard lets the service and app know about any sensor changes with Weave over the Wi-Fi network. If the power goes out, Nest Detect can still talk to the keypad with Weave + Thread. And Nest Guard, running on its backup battery, can still talk to the service using Weave over cellular.
Product-driven design.Weave is not a solution looking for a problem – its features are driven by requirements we identified while building our ecosystem of products. Weave's encryption protocols were designed to fit the processor and memory constraints of our thermostat and our smoke and CO alarm.
It has a compact message format and communicates only when it needs to, so security sensors can run on batteries for years. And because Weave has tiered-trust domains, sensitive operations like disarming security or unlocking the door are only accessible by the right devices.
Weave powers Nest products, along with upcoming products like a Yale lock made in collaboration with Nest. Because they share Weave as their common language, the Yale lock and the Nest Secure alarm system work better when they're together. When you unlock your front door, the lock will automatically tell Nest Secure that it's safe to disarm, so you don't have to. The lock even inherits Nest Guard's robustness, staying fully operational even when power or the internet goes down.
