Need help replacing the old double switch (top two photos) for the new smart switch for my Grandma so she can have the lights come on at dusk till Dawn for security.

I am (mostly...) a fan of use the right tool for the job.

Can a WiFi controlled smart switch be programmed to track sunrise/sunset? Sure.

But how about a simple photocell fixture? That is a far simpler technology that has been around "forever". No computer, smartphone, etc. needed. No worry about forgetting how to program it. Automatically on/off every day with sunset/sunrise.

Alternatively, you can get a motion sensor light. Automatically turns on when it detects someone within range and stays on until there is no movement for a while.
