Wyze Threaded Recessed Bracket

Use a 1 inch bit to recess the head below the surface. For the sensor use a 7/8 inch bit to drill about 2 inches deep. Use a 5/8th inch bit to drill about 2 inches for the magnet side. Be sure those sides line up. If it feels a little tight then hit it with the bit again. If it feels loose use some plumbing tape. If you don't like the threads you can use my previous design and someone has even remixed that to be the same just thicker.
