Leviton WIFI Switches and Dimmers, What if Internet Connection Goes Down
Leviton's Decora Smart WIFI switches and dimmers use the Internet and Leviton's private cloud servers for set up and operation. What happens if the Internet connection in the house goes down?
Timers will still function
Schedules / Timers still work as they are saved in the devices themselves
Without Internet the app cannot be used to configure/control devices, even if the router is still functioning as they rely on the cloud for configuration/control
If AC power is lost to the devices, it relies on the cloud to reset the time when power is restored. If the device doesn’t have the time, schedules won’t run. So Internet is required after a power failure to restore the on board time and therefore to have schedules work after the power failure.
