Nest Protect software update history

This article is the software update history of the Nest Protect, including the dates of each new release, summary of what’s new, changes and enhancements.

Your Nest Protect will automatically download the latest software if it is connected to the Internet. You don't need to do anything.

Software updates are rolled out gradually, and usually take a few weeks to make it to all Nest Protects. This is to make sure that the process goes smoothly for all our customers. If you notice there's a new update listed below, but it's not on your Nest Protect yet, it should automatically update.

Your Nest Protect will still warn you in the case of an emergency or Heads Up alert, even if it isn’t connected to the internet, and it has older software.

Your Nest Protect software is tested by Underwriter’s Laboratories, the California State Fire Marshal, and other independent certification bodies, to ensure that it meets the applicable certification standards in countries where it’s sold.
