Have you ever woken up in the middle of the night because your smoke alarm was chirping? Google Nest Protect has a better way: Nightly Promise. Each night when you turn out the lights you’ll get a quick green glow which means the batteries and sensors of Nest Protect are working. This means no dreaded chirps at midnight so you can sleep safe and sound.
| Nest Protect constantly monitors its internal sensors, batteries and Wi-Fi connection. Nightly Promise lets you know the results of this Self Test every night when you turn out the lights. And if the Nest Protects in your home are connected, Nightly Promise doesn't just let you know if the alarm nearest you is working. It shows you the status of every Nest Protect in the house. |
 |
| If you see your Nest Protect glow green as you turn out the lights, you know its sensors, Wi-Fi, and batteries are working, as are the sensors, Wi-Fi, and batteries of all your other interconnected Nest Protects. |
|
| If your Nest Protect glows yellow instead, that means there's a problem with it or with another Nest Protect in your home. Push the Nest button to hear its message: |

What if I don't see Nightly Promise when I turn off the lights?
Nightly Promise uses the ambient light sensor and will only turn on when the room goes from bright to dark. If you don't see the Nest Protect light when you turn off the lights at night, the room might not be dark enough. Occasionally, if the room becomes dark quickly, Nightly Promise will come on during the day. For example, drapes blowing in the wind or shutters closing can cause Nightly Promise to light up.
If you missed Nightly Promise, simply turn the room lights on for at least 30 seconds, then turn them off again to see the Nightly Promise light. You can also review any Nightly Promise messages with the Nest app or on the Web.
If I see Nightly Promise on one Nest Protect, does that mean they're all working?
Can I turn off Nightly Promise?
You can turn off the Nightly Promise light with the app. Nest Protect will continue to perform Self Test to ensure everything is working, but it will not glow green when you turn off the lights at night. If a problem is identified during Self Test (such as a low battery) Nest Protect will still tell you by glowing yellow and sending a message to the Nest app.
