Sadly there was some issues with the Firmware and one of them is Grid missing and false alarms.. They have removed the FW from being able for DL and are working to try and bring back an updated FW that will make it better then the current 8xx version.. Right now the most stable Version is 702 while it does have it down falls it is by far one of the best I have installed to date...
Just so you know it isn't the Smarthome app that took away the grid it was the update out of 702 FW of the Camera..
