So I was previously using a smaller reed switch to confirm my garage is closed, but I had to the magnet so close to the sensor that a slight change would have it not read.
I found this larger style (https://www.amazon.com/gp/product/B07ZBT28L8/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1) and its been working great. The magnet triggers the sensor from over 3" away! Its much larger, but I care more about function, at least in the garage. The sensor is actually meant to go on the floor, but I just mounted it to the side of the garage roller rail.
Just wanted to share in case others who are in the same boat are searching.
Heres the sensor and magnet.
Then I just have the sensor going into my Shelly1 (grey wires)
