I have two wyze doorbells. They work great during the day time but at night at least one goes off line and I have to turn off power to get it to restore. At first it use to be only the carport doorbell but since I turned off night vision mode, it does not go offline as much. I have also turn off night vision mode on the front door,
Its not the wifi because not only I changed to a mesh node wifi, I placed an extender in the carport area for the carport doorbell.
