If you have the actual Hydrowise wifi controller and you installed the app on your smart phone You should be able to generate the zones you want to control and the start and run time on the app.
We have had it for 2 years and have had 0 issues with it.
It does communicate on 2.4 ghz not 5 if your router uses both.
Make sure you put in the pass word for the router in the Hydrowise unit.
We replaced the klunky mechanical unit with the Wifi unit.

I have had good luck contacting Hunter both by email and phone. If you have questions they have the answers.

Our watering bill went from almost $200 per month to about $20-30 per month.
It also checks on the weather and will not water if not needed.
