Looking for some help/ suggestions on a garage door cam / remote (cell phone) operated monitor . I go to work early AM and every now and then i get few miles out and cant remember if i closed the door and have to turn around and drive all the way back. Elderly mom lives with me and shes not good on stairs anymore and id rather NOT have her going down to check it and end up falling as it wont end well .Currently have a Liftmaster opener and its NOT wifi capable .Anyone have or use one of these devices and have good luck with it? Thanks for any help.
