Google's Nest Protect connected smoke detector has been discontinued

Google has discontinued the Nest Protect connected smoke detector. In a post on the Google Nest Community Blog, Google has shared that the Nest Protect is no longer being produced. We've seen signs that this was coming, but until now, we hadn't heard anything specific. Existing Nest Protect units will continue to function; Google says they "will continue to work as they always have through their expiration dates and will continue to receive software and security updates."
