8. Make sure you select “Allow notification” when asked.

9. If you getting this error after app upgrade. “Your input is invalid. Please fix it and try again. Bad request”. Try to download the latest version of the app from the app store.If that doesn’t work, please logout and login again. For iphone, go to ‘About’ tab in the monitor app to logout.
If that still doesn’t work, delete the app and go to phone’s settings to also delete the app data.

Check if you are connecting to the guest WiFi. Many routers don’t allow the devices on guest WiFi to communicate with other devices in the network. This would cause setup to fail.

12. The garage door is always showing open even though it is closed.
Rotate the monitor device 180 degree and check again.

13. If you have Wifi repeater/extender and if they use a different SSID than the main router, choose whichever SSID has the strongest signal to connect the monitor to.

The direction of the device matters. You probably got the up side down.
See the picture for how to attach the device to the garage door.

16. Login failed with Android phones. Try uninstall GDB monitor app and reinstall. If still not working, go to your phone’s settings > Apps > GDB Monitor > Storage.  Click ‘Clear data’ button and click ‘Clear cache’ button.  After that, try logging in again.

17. For iOS 13.0, there’s known issue for the app to get WiFi SSID. Please upgrade to newer version. For iOS 13.1 and 13.2, if the issue of getting WiFi SSID persists, reboot the phone and try again.
