+The `essent` platform uses [PyEssent](https://github.com/TheLastProject/PyEssent/) to communicate with the (undocumented) API of Dutch energy provider Essent. It provides sensors for each of your meters and tariffs, updated daily.
+
+To add Essent to your installation, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+sensor:
+  - platform: essent
+    username: YOUR_USERNAME
+    password: YOUR_PASSWORD
+```
+
+{% configuration %}
