How big is this pond or is it a retention lake for rain water runoff? If you're in a HOA, check if you're allowed to draw from the pond or lake.
Generally for the best performance with 1" valves, bring 1" pipe to the sprinkler tee and then reduce it to 1/2" to the sprinkler. There are several WiFi controllers, I have a Rainbird WiFi ESP-Me four zone controller. .
How many sprinklers per zone? 120 v pump is not the greatest but as long you do not over do the number of sprinklers. Type of sprinklers make a big difference. Pop-ups uses the least amount of water. Usually 1/4 to 1/2 gallon per minute. Rotary type can be over one gallon per minute. Old fashion impact type 3-4 gallon per minute.
For your 1/2-hp pump, 4-6 pop ups per zone, rotary 2-3 per zone. Impact 1-2. The best way is installed sprinklers that use about 1/2 the pump rating. If it rated at 6 gallons a minute, per zone should use 3 gallons per zone.
When drawing from a lake or pond, elevation impacts the performance of the pump. The pump instructions should show a chart. Most small pumps has a 1.5" input pipe. You'll also will need an intake screen and a check valve near the inlet above or below the water.
