Do not buy Garage door controller, I have a very bad experience, doesn’t work from time to time, it’s critical for this type of the devices
When you say it doesn’t work, what do you mean? Are you trying to open or close it from the app? A rule isn’t working? Is it not detecting the QR code correctly? Not sending you a notification? Is your camera going offline?
Did you buy the GDController separately from the camera or in a bundle with the camera?
Is there signal interference?
