+
+The `homematic` notification platform enables invoking Homematic devices.
+
+To use this notification platform in your installation, add the following to your `configuration.yaml` file:
+
+## {% linkable_title Configuration %}
+
+```yaml
+# Example configuration.yaml entry
+notify:
+  - name: my_hm
+    platform: homematic
+    address: NEQXXXXXXX
+    channel: 2
+    param: "SUBMIT"
+    value: "1,1,108000,8"
+```
+
+{% configuration %}
+address:
+  description: The address of your Homematic device. The address is the serial number of the device shown in the CCU in the `devices` section in the column `serial number`.
+  required: true
+  type: string
+channel:
+  description: The channel of your Homematic device. 
+  required: true
+  type: integer
+param:
+  description: An additional parameter for the Homematic device. 
+  required: true
+  type: string
+interface:
+  description: Set the name of the interface from the config.
+  required: false
+  type: string
+value:
+  description: This is the value that is set on the device. Its device specific.
+  required: true
+  type: string
+{% endconfiguration %}
+
+### {% linkable_title Usage %}
+
+`homematic` is a notify platform and can be controlled by calling the notify service [as described here](/components/notify/).
+
+Only the `data` part of the event payload is processed. This part can specify or override the value given as configuration variable:
+
+```json
+{
+  "data": {
+    "address": "NEQXXXXXXX",
+    "channel": 2,
+    "param": "SUBMIT",
+    "value": "1,1,108000,8"
+  }
+}
+```
+
+It is possible to provide a template in order to compute the value:
+
+{% raw %}
+```json
+{
+  "data": {
+    "value": "1,1,108000{% if is_state('binary_sensor.oeqxxxxxxx_state', 'on') %},1{% endif %}{% if is_state('binary_sensor.oeqxxxxxxx_state', 'on') %},2{% endif %}"
+  }
+}
+```
+{% endraw %}
+
+You can also specify the event payload using a group notification (instead of specifying the value for the notify itself):
+
+{% raw %}
+```yaml
+notify:
+  - name: my_hm
+    platform: homematic
+    address: NEQXXXXXXX
+  - name: group_hm
+    platform: group
+    services:
+      - service: my_hm
+        data:
+          data:
+            value: "1,1,108000{% if is_state('binary_sensor.oeqxxxxxxx_state', 'on') %},1{% endif %}{% if is_state('binary_sensor.oeqxxxxxxx_state', 'on') %},2{% endif %}"
+
+alert:
+  temperature:
+    name: Temperature too high
+    done_message: Temperature OK
+    entity_id: binary_sensor.temperature_too_high
+    can_acknowledge: True
+    notifiers:
+      - group_hm
+```
+{% endraw %}
+
+Please note that the first `data` element belongs to the service `my_hm`, while the second one belongs to the event payload.
