Nest Protect Weave Mesh

[KnoxNest]

Hi,

I have a client that wants to use multiple Nest Protect (Gen 2) devices in a larger installation project.  Approximately 10000 square feet over four levels.  The product documentation suggests that each device only has a range of 50 feet to another device.  My question is will these devices act as a mesh network across a longer range?  If Device 1 is at zero feet, Device 2 is at 50 feet, Device 3 is at 100 feet, Device 4 is at 150 feet, and Device 5 is at 200 feet, when Device 1 alarms will device 5 also alarm even though they are 200 feet from one another?  In other words, will the alarm signal be transmitted from Device 1 to Device 2, then Device 2 to Device 3, then Device 3 to Device 4, then Device 4 to Device 5, or does Device 1 have to directly reach Device 5 wirelessly for the interconnect to work?  Thanks!

Hello @KnoxNest,

That's a great question about Nest Protect's mesh networking capabilities for your large project. While the product documentation mentions a 50-foot range, Nest Protect (Gen 2) utilizes a multi-hop communication system. This means:

Individual Range: Each Nest Protect can directly communicate with other devices within a 50-foot (15-meter) radius.

Mesh Networking: The beauty lies in their ability to relay signals through other Nest Protects in range. Imagine a chain reaction: if Device 1 detects smoke and can't directly reach Device 5 (200 feet away), it can send the signal to Device 2 (within 50 feet). Device 2 then relays the message to Device 3, and so on, until the entire network, including Device 5, is alerted.

In your example,

• Device 1 can directly connect to Device 2 (within 50 feet).
• Device 2 then picks up the signal and relays it to Device 3 (even though Device 3 is beyond 50 feet from Device 1).
• This relaying process continues, ensuring Device 5 also alarms despite being 200 feet from the initial source.

By understanding Nest Protect's mesh networking capabilities and implementing strategic placement, you can achieve a reliable smoke and CO detection system for your client's large installation project.

Let me know if you have any further questions. Thank you.

Best regards,

Jorge.

Thank you!  This makes great sense and is a great feature.

I'd love to see the system allow more than 18 devices as well!
