Cant seem to find this already in here, so adding after suggested in another help area.
Can we please have an extension kit for the Ring door view cam? I have a door 70mm thick and would like to use the door view cam. I live in a rented home, so I can’t fit the other options cos they require drilling holes. And I also would like the knock sensor feature (delightful local children like to knock on doors and run off 
). Seems from various help sites, etc. that a lot of people want this, and various countries have to have thick doors as standard. Please help out people who want to give you money! Maybe it’ll make up for you guys promising HomeKit compatibility for 2 years…
