Detached Garage Ideas

New member here. I'm thrilled that 99% of what my old security company covered is covered by ring at about 20% of my previous cost.However, I'm disappointed that there doesn't seem to be a solution for a detatched garage. I currently have a range extender and contact sensors installed, but now I see that these do not work in cold temps.I want to know if there is a break-in in my garage. How have others solved this problem? I have the Nexx Garage app so at least I can see if the door is open, but I'd also like to add some kind of security alert.Thanks for any suggestions!tt
