I'm not sure Google keeps a list of the latest firmware publicly anywhere, to my knowledge. As long as your Nest Protect is connected to Wi-Fi and the internet, it should update itself automatically. If it’s been more than a week and it still hasn’t received the latest software, you can reset its connection to the Wi-Fi network to try to push things along:
Yes, I did that and it worked. Thanks
What about the Model number? One of my recently purchased devices had a Model number of Topsz-2.0. When I performed the procedure you mentioned it upgraded to Model: Topaz-2.9. Some of my devices are Topaz-2.33 and others are Topaz-2.9, even after performing the same steps. It seems inconsistent.
The best suggestion I can give is to restart or Factory Reset each of them around the same time, so hopefully they are all on the same update. I hope that helps! I wish I had more insight, but these devices mainly function best on a very strong, steady wifi connection.
Is there a way to get the firmware file, drop it in the nest via usb so it can update to the new firmware.
I connected my nest protect via usb and copy my nest pli file to my desktop, open it and is version 3024.
I can´t connect the smoke detector to any wifi. Tried my wifi, the neighbor, my sister, and my parents, didn´t succeed in any attempt.
