Having no Wifi service in my house my main source of internet access is an iphone with an unlimited data account. Using the Wyze App on my phone i set the cameras up and view them with the app on my iPad. Same set up for my old v2’s. Worked fine for a day or two then “Device offline” and “Error code 9” would show up and i would do a pull power reset then a full factory reset to get the cameras workable for another day or two.
With my new batch of 4 v3’s the same issues popped up and it suddenly occurred to me to use the Wyze App on my iPad only, so i deleted the app from my phone and use the personal hotspot for the cameras to view/control/store videos with the Wyze app on my iPad. When i leave the house with my phone and return i turn the hotspot on and the camera as get picked up almost immediately. Haven’t had the issue in almost 2 weeks.
