Nest Protect software update history

This article describes changes and enhancements included in software updates for the Google Nest Protect.

If your Nest Protect is connected to the Internet, it will automatically download the latest software and you don’t need to do anything. Even if you haven’t connected your Nest Protect to the Internet, and have an older version of the software, your Nest Protect will still warn you in the case of an emergency or Heads Up alert.

Software updates usually take a few weeks to make it to all Nest Protects that are connected to Wi-Fi, to make sure that the process goes smoothly for all our users. If you notice there's been a new update listed below, but it's not on your Nest Protect yet, hang tight - we're working to get the latest software version out to everyone.

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