+[EDP re:dy](https://www.edp.pt/particulares/servicos/redy/) is a Home Automation platform from Portuguese energy provider EDP, that allows control of appliances and other devices, as well as monitoring power consumption. This component allows integrating EDP re:dy into Home Assistant.
+
+## {% linkable_title Configuration %}
+
+You will need your re:dy login information (username and password) to use this component.
+
+To set it up, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+edp_redy:
+  username: YOUR_USERNAME
+  password: YOUR_PASSWORD
+```
+
+{% configuration %}
+username:

+  required: true
+  type: string
+password:
+  description: The password for accessing your re:dy account.
+  required: true
+  type: string
+{% endconfiguration %}
+

+
+* A switch per toggleable device (switch, plug, etc).
+* A sensor per each device that reports power consumption (SmartMeter, plug, meter)
