Tested with Hass.io, HA 0.103.0, iOS 13.3, iOS Companion 2.0, iPhone 8. Standby switch and binary sensor sync with Rachio mobile app correctly. Switch was toggled several times and monitored with the mobile app.

@springstan thank you! was worried since this is my first PR and didn't want to get yelled at :)
@garyak can you also make sure that the online sensor is working for you? Also not sure if you can test the zones? I hope I didn't mess anything up and I can't water here due to the weather....

[garyak]

@omriasta sure. Balmy 37 degrees here today. I tested my two zones. Both function as expected and indications from the Rachio mobile app, iOS Home, and HA are all accurate. I had no previous issues with the binary_sensor.sprinklers_online function. So far, so good. Thanks again.
