Wyze seems to me to be a very low budget company operating on a shoestring. When they have a serious problem they ignore it. Most people move on to new suppliers. Wyze works off of the fact there are 8 billion people in the world and they can afford to irritate a few and those folks will move on. The old ignore the problem and it will go away. I quite using the products they have except certain cameras. If you are thinking these would be good for security they will more than likely show you what happened but not soon enough to alert someone. Kind of like the police, they show up after the fact. Sometimes they don’t even alert you. They will capture the video but no alert, that is really not to helpful. I had 3 products that became worthless. First were the original sensors, I took that as a learning experience but when Wzye bricked the 1st ver. battery cam,WOC, and refused to accept blame and fix the issue that became personal. I no longer can in good faith recommend their products. Then they bricked the 1 ver. Wyze bulb, 2019ver. That sealed the deal. If you notice there is a pattern. 1st versions quit working after updates whether it is the device or the app they quit working and wyze accepts no responsibility. They like to blame everything else, routers, phones etc. If their products are that susceptible to change then don’t make the change. To bad Meross does not make cameras because there stuff seems to be very durable and they very seldom update the firmware and app but then again if you do it right the 1st time there is no reason to update.
