Nest Secure Has an Unlisted, Disabled Microphone

An anonymous reader quotes a report from Android Authority: Owners of the Nest Secure alarm system have been able to use voice commands to control their home security through Google Assistant for a while now. However, to issue those commands, they needed a separate Google Assistant-powered device, like a smartphone or a Google Home smart speaker. The reason for this limitation has always seemed straightforward: according to the official tech specs, there's no onboard microphone in the Nest Secure system. However, Google just informed us that it is right now rolling out Assistant functionality to all Nest Secure devices via a software update. That's right: if you currently own a Nest Secure, you will be able to use it as a Google Home very soon. That means somewhere in the Nest Guard -- the keypad base station of the Nest Secure -- there might be a microphone we didn't know existed. Either that or your voice commands are going to be heard by another product (like your phone, maybe) but Assistant's output will now come from the Nest Guard, if you happen to be in the range of that device. UPDATE: Google has issued a statement to Android Authority confirming the built-in microphone in the Nest Guard base system that's not listed on the official spec sheet at Nest's site. The microphone has been in an inactive state since the release of the Nest Secure, Google says. This unlisted mic is how the Nest Guard will be able to operate as a pseudo-Google Home with just a software update.
