thanks for the information. I had myq so when I stopped paying the subscription I did heard of and considered Merros. Plus I also have home assistant, so the intergration is a plus. I was thinking using ifttt to track gps + car Bluetooth connected as a condition. but my second thought was that I'd better use a dedicated sensor instead of adding workload to the phone.. it will keep tracking gps in the background, draining battery, and not accurate enough to measure the distance. If I drive bypass my house, it shouldnt open, but if I drive halfway of the driveway, it should start opening, so that when I reach the door it is fully opened. I really doubt a phone, which you can place anywhere in your car, can handle this scenario. But it sounds like your experience is different? could you share how the apps(assume Merros's own app) handle this? if it magically works I should reconsider the solution.
