+
+```yaml
+# Example configuration.yaml entry
+climate:
+  - platform: sensibo
+    api_key: <your_key_here>
+```
+
+Configuration variables:
+
+- **api_key** (*Required*): Your API key.
+- **id** (*Optional*): A unit ID or a list of IDs. If none specified then all units acessible by the `api_key` will be used.
+
+To get your API key visit <https://home.sensibo.com/me/api>
+
+<p class="note">
+If you create the API key using a dedicated user (and not your main user),

+done in the app and actions done by Home Assistant.
