There is no neutral wire on the current switch. Do I just install the ground and the two live load wires?

For the goofball that says ground = neutral, send him the funeral bill. and the fire damage billing. NEVER EVER use ground in place of a neutral. in 120 volt circuits, Neutral is a wire (usually white) which CARRIES "used" return current back to the box... RETURN current EQUALS the current that the AC device (light, motor, etc...) is consuming (using). NEVER use multiple "hots" and connect to just one neutral, as the "hots" current draw is the total of all "hots", you'd be overloading the (white) neutral return wire. Each "hot" must be paired with a "white" neutral of the same gauge wire to complete the breaker (fused) protected circuit. These switches need a neutral, and as another has explained, it is because the "brain" itself consumes current, and must return it to the box, not just switch a "hot" pole on/off.

what happens if someone turns the switch off? Can I still turn it on over voice? i.e. Alexa

The short answer is: Yes you can still turn it on and off with Alexa by voice or Alexa app or the smart life app. It is connected through WiFi so the switches WiFi is active at all times. The long answer is: The only thing that might bother you is the little light that is actually on the switch itself does not turn on or off if you use Alexa or app to turn your lights off and on. The light on the switch only turns on an off when you physically push it. Basically when the light on the switch gets out of sync with the off and on if you use any other method that pushing the switch. But it’s really not that much of a bother unless you are anal retentive and absolutely must have the light on the switch on when your light is on.

Can this switch be programmed to turn on lights at sunset or turn off at sunrise without a need to adjust the times every day? Lutron has this feature

Yes. With the SmartLife app you can program the switches to turn on/off at sunset/sunrise based on your location.

is there a minimum load requirement for this switch?

There shouldn't be a minimum load requirement for a simple switch. Some dimmers that work with LED bulbs have a minimum load requirement, but this is a switch, not a dimmer.
