The instructions for how to use a wire nut might want to suggest checking your local electrical code. In my city, you are required to wrap wire nuts in electrical tape (presumably in case the wires pull out). (Pictures below.)
I noticed that the extension wire pulled out from the spade’s insulation, so I had to wrap that in electrical tape too. (Picture below.)
The Wyze app does not display the doorbell’s image correctly on a phone with a 18:9 aspect ratio. If nothing else, it would be nice if the image were moved down out of the notification area. (Picture below.)
I also noticed that when I changed the video quality from SD to HD, the change was not reflected in the user interface until I exited that screen and opened it again.
