The subject pretty much says it all. I installed this back in Nov. 2015 and it worked great until a couple weeks ago. The tilt sensor still works fine and when I attempt to open or close the device receives the command fine and even triggers the beeping noise it does for five seconds before opening or closing, but then it never actually does anything. The only other oddity is that the flashing light no longer works either and that failed at the same time as far as I can tell.
Since it is out of warranty, does anyone have any suggestions that I could try before I buy a new one?
Also, if I end up having to buy something new, is there a different device anyone would recommend? My needs are simple–must work with SmartThings and must open and close my door. I prefer wired to wireless as I figured it would be more foolproof, but look at me now!
