Hey @marcster. We do not have this feature at this time, as the Ring Alarm system communicates on a Z-Wave network that the Base Station creates during setup. All devices, such as the contact sensors, motion sensors, keypad, and do on, will talk on the Z-Wave network. Therefore, if your wifi goes down, the Z-Wave will stay intact as long as your Base Station is online and functioning. If you Base Station loses connection to the internet through a wifi jamming that may occur, if you have the Ring Protect Plus Plan, the cellular backup from the SIM card within it will keep the Base Station online.
When it comes to the individual Alarm Devices that the Base Station talk to, if the Z-Wave signal/connection is ever weak, you will see an error message like the one in the attached picture! This is what it looks like for a range extender, when it has a weak signal. Hope this helps clear it up for you.
