Sorry for the late reply. I wanted to follow up and ensure you are good to go. Please let me know if you are still having any trouble from here, as I would be happy to take a closer look and assist you further.
I tried to chat with you several times but you keep answering questions I never asked and also you close the chat each time I ask this question and here is the problem and a lot of people have it to.
I have the Google Nest protect smoke detector but when i try to connect Nest to Google Home app it asks me to login with an Nest account but i only have an Nest account signed with Google because there is no other way to sign up to Google Nest which leads to no possibility to connect them together?
(It is working in the same home as Google Home but in the Nest app)
