So we bought a home a year ago and I can't add one of my nest protects because it is too high on the ceiling (out of reach) for me to scan the barcode. Is there a way to add the product by long pressing the button if I find a pole or something to reach it?
Sorry for the delayed response but thanks for reaching out to the Google Nest Community.
I'm afraid that in order to add a Nest Protect to your Nest account through the Nest app, you really need to take it down to scan the QR code or enter the entry key nest to it. I also suggest that you write down the Entry Key for each Protect you install and keep this number in a safe place in case you need to redo the setup in the future,
