OpenZWave (beta)	Instructions on how to integrate OpenZWave with Home Assistant.	Switch	0.110	Local Push	true	@cgarwood @marcelveldt @MartinHjelmare	ozw

This integration allows you to utilize OpenZWave's ozwdaemon to control a Z-Wave network over MQTT.

Requirements

• MQTT server and the MQTT integration set up in Home Assistant.
• The ozwdaemon installed and running in your network. For Home Assistant Supervisor there's an official add-on named OpenZWave available from the add-on store.
• Supported Z-Wave dongle compatible with OpenZWave 1.6. See this list of controllers. The Z-Wave controller dongle should be connected to the same host as where the ozwdaemon is running.

Configuration

This integration can be configured using the integrations in the Home Assistant frontend.

Menu: Configuration -> Integrations.

Click on the + sign to add an integration and click on OpenZWave (beta). After completing the configuration flow, the OpenZWave integration will be available.

Secure network key

The secure network key is set in the settings for the ozwdaemon and not in the integration configuration.

Services

Service ozw.add_node

This service will set the controller into inclusion mode and should be used to add a device (node) to the Z-Wave network. Call the service and then perform the device-specific procedure, according to the device manual, to add your device to the network. Make sure the controller is connected to the host where the ozwdaemon is running, when performing this operation.

Service Data Attribute	Required	Description
secure	no	Add the new node with secure communications. Secure network key must be set. This process will fallback to add_node (unsecure) for unsupported devices. Note that insecure devices can't directly talk to secure devices.
instance_id	no	The OZW Instance/Controller to use, defaults to 1.

Service ozw.remove_node

This service will set the controller into exclusion mode and should be used to remove a device (node) from the Z-Wave network. Call the service and then perform the device-specific procedure, according to the device manual, to remove your device from the network. Make sure the controller is connected to the host where the ozwdaemon is running, when performing this operation.

Service Data Attribute	Required	Description
instance_id	no	The OZW Instance/Controller to use, defaults to 1.

Service ozw.set_usercode

This service will set the usercode to X at code slot Y. Valid usercodes are at least 4 digits.

Service Data Attribute	Required	Description
entity_id	no	Lock entity or list of entities to set the usercode.
code_slot	yes	The code slot to set the usercode into.
usercode	yes	The code to set in the slot.

Service ozw.clear_usercode

This service will clear the usercode in code slot X. Valid code slots are between 1-254.

Service Data Attribute	Required	Description
entity_id	no	Lock entity or list of entities to clear the usercode.
code_slot	yes	The code slot to clear the usercode from.

Service ozw.set_config_parameter

This service will set the specified configuration parameter to the value specified to allow device-specific configurations. Example of this would be setting notification LED colors on switches.

Service Data Attribute	Required	Description
instance_id	no	The OZW Instance/Controller to use, defaults to 1.
node_id	yes	Node id of the device to set configuration parameter to (integer).
parameter	yes	Parameter number to set (integer).
value	yes	Value to set for parameter. (String or integer value for list, string for bool parameters, integer for others).

Events

Event ozw.scene_activated

This event is fired upon scene activation. The data in the event will vary depending on your particular Z-Wave device, however, here is an example from a Zooz ZEN27 Dimmer when the down button is pressed 3 times.

    "event_type": "ozw.scene_activated",
    "data": {
        "node_id": 9,

    },
