+## Home assistant
+
+For integration with Home Assistant, the following MQTT sensor can be used to create a read only sensor
+
+```yaml
+- unique_id: "coffee_machine"
+  name: "Coffee Machine"
+  state_topic: "homeconnect/coffeemaker/state"
+  value_template: "{{ value_json.PowerState }}"
+  json_attributes_topic: "homeconnect/coffeemaker/state"
+  json_attributes_template: "{{ value_json | tojson }}"
+```
+
+## Notes
+- Sometimes when the device is off, there is the error `ERROR [ip] [Errno 113] No route to host`
+- There is a lot more information available, like the status of a program that is currently active. This needs to be integrated if possible. For now only the values that relate to the `config.json` are published
