@JudyL1945,

For most models, there are two buttons below the paddle, the Right being a Reboot, and the left being the Reset.

Start with Pressing the Reboot Button to see if this will bring the devices back online.

If the devices are still not operating correctly, I would recommend using the reset button to attempt a soft reset of the network settings (5Seconds) or a Factory Reset of all settings by holding the button for 10 seconds.

I would confirm that the light switch for your front porch is wired correctly, as the light should still be able to control the light manually.
