To test the sprinkler, you can use the instant manual run feature on the Home page to turn on and off the zones instantly. The blue play button is for instant manual run for your zones.
You can also use the “Test run” feature on the login page. In this way you do not need to have a home Wi-Fi or create a Netro account. Your phone is directly connected to the Wi-Fi network hosted by the Sprite. This mode allows you to turn on and off the zones without involving the Netro cloud server.
