This is really a "getting started" issue, however, I have 3 nest Battery cameras I purchased. The initial set up was fine and they worked fine. I had to overhaul my home network and had to reset passwords. In that, i could never get the camera's to reset of link to the new password. So I took them down and did a factory reset on them. Removed them form "google Home" and tried to reinstall them as new devices. This is where the problem is..... I can get to the point of waiting for the blue light to begin flashing in the set up and it never does. EVER! I have reset the camera's several times, tried and tried again but nothing. Any help would be greatly appreciated.
