If you change your router, one solution is to change your new router's configuration to the same wireless SSID and Wi-Fi network password as your previous router.
When changing the Wi-Fi SSID or password each device will need to rejoin the network; however, you will not need to rename the devices or recreate the schedules. The Reconfigure Wireless feature in the My Leviton app makes the process simple. For First Generation devices (model number starts with DW) click here.
