+
+To enable it, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+hydrawise:
+  access_token: YOUR_API_KEY
+```
+
+{% configuration %}
+access_token:
+  description: The API KEY assigned to your Hydrawise account.
+  required: true
+  type: string
+scan_interval:
+  description: The time interval, in seconds, to poll the Hydrawise cloud.
+  required: false
+  type: int
+  default: 30
+{% endconfiguration %}
+
+To get your API access token log into your [Hydrawise account](https://app.hydrawise.com/config/account) and in the 'My Account Details' section under Account Settings click 'Generate API Key'. Enter that key in your configuration file as the `API_KEY`.

+
+When `auto_watering` is `on` the irrigation zone will follow the Smart Watering schedule set through the Hydrawise [mobile or web app](https://www.hydrawise.com). When the `auto_watering` switch is `off` the zone's Smart Watering schedule is suspended for 1 year.
+
+When `manual_watering` is `on` the zone will run for the amount of time set by `watering_minutes`.
+
+```yaml
+# An example that enables all the switches, and sets the manual watering time to 20 minutes.
+switch:
+  - platform: hydrawise
+    watering_minutes: 20
+```
+
+```yaml
+# An example that enables only the manual control switches.
