The other day I installed a Rachio 3 irrigation controller. It needs to be connected to a WiFi so I can setup the water zones. I went through the process on my iphone after downloading the app and an error came up. The app didn't ask for a password. I backed up a few steps in the app and all of sudden it seemed to be connected to the WiFi. In the mean time somewhere I pushed a button on the front that had a WiFi symbol near it. The button is not mentioned in the instructions or on the app. How does this work that something can connect to my WiFi without a password?
Thanks.
