"re-register" a dot
I set up a Dot for a friend using his Wi-Fi and my cell phone - - my friend does not have a cell phone. Everything went well. When I returned to my house 900 miles away, my friend reported that he could here activity on my Eufy doorbell on his Dot. I believed that if I "de-registered" his Dot on my phone that would alleviate the problem. Instead, his Dot is now off line. How can he "re-register" it again without a cell phone ??
