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 automatically downloads the latest software if it's 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. There is a gradual rollout to make sure that the process goes smoothly for all of our customers. If you notice 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 a Heads-Up alert, even if it isn’t connected to the Internet and its software is an older version.
Your Nest Protect software is tested by independent certification bodies to ensure that it meets the applicable certification standards in countries where it’s sold.
