- Nest Secure products (Guard, Detect and Tag) stopped connecting to the internet and are no longer functional or controllable through the Nest app.
- Dropcam, an earlier version of Google’s smart camera, stopped working as well. Users would have had to download videos before this date to save them. Former Dropcam owners received either an indoor Nest camera as a replacement (if they had a Nest Aware subscription) or 50% off a Nest camera.
- Nest x Yale Lock no longer connects to Wi-Fi through the Nest Guard hub, so you won’t be able to lock and unlock your door through the Nest app (you’ll still be able to use the keypad). The lock will only connect to Wi-Fi with a Nest Connect device, which Google sent to eligible users for free as a replacement.
- Nest cameras, video doorbells and life safety alert products available for purchase on the Google store still function normally and connect to the Nest app.
