## Automations
### Device automations
Z-Wave JS has support for device triggers and conditions. To use a device automation, use the automation UI to select the "Device" trigger/condition type, and then pick your Z-Wave JS device. Under trigger/condition types, you will see Z-Wave JS specific entries.
### `zwave_js.value_updated` trigger
Z-Wave JS provides the `zwave_js.value_updated` trigger platform which can be used to trigger automations on any Z-Wave JS value update, including Z-Wave values that aren't supported in Home Assistant via entities. While they can't be authored from the automation UI, they can be authored in YAML directly in your `configuration.yaml`.
```yaml
# Example automation trigger that fires whenever the `latchStatus` value changes from `closed` to `opened` on the three devices (devices will be derived from an entity ID).
trigger:
platform: zwave_js.value_updated
# At least one `device_id` or `entity_id` must be provided
device_id: 45d7d3230dbb7441473ec883dab294d4 # Garage Door Lock device ID
entity_id:
- lock.front_lock
- lock.back_door
# `property` and `command_class` are required
command_class: 98 # Door Lock CC
property: "latchStatus"
# `property_key` and `endpoint` are optional
property_key: null
endpoint: 0
# `from` and `to` will both accept lists of values and the trigger will fire if the value update matches any of the listed values
from:
- "closed"
- "jammed"
to: "opened"
```
#### Available Trigger Data
In addition to the [standard automation trigger data](docs/automation/templating/#all), the `zwave_js.value_updated` trigger platform has additional trigger data available for use.
| Template variable | Data |
|------------------------------|--------------------------------------------------------------------------------------------|
| `trigger.device_id` | Device ID for the device in the device registry. |
| `trigger.node_id` | Z-Wave node ID. |
| `trigger.command_class` | Command class ID. |
| `trigger.command_class_name` | Command class name. |
| `trigger.property` | Z-Wave Value's property. |
| `trigger.property_name` | Z-Wave Value's property name. |
| `trigger.property_key` | Z-Wave Value's property key. |
| `trigger.property_key_name` | Z-Wave Value's property key name. |
| `trigger.endpoint` | Z-Wave Value's endpoint. |
| `trigger.previous_value` | The previous value for this Z-Wave value (translated to a state name when possible). |
| `trigger.previous_value_raw` | The raw previous value for this Z-Wave value (the key of the state when a state is named). |
| `trigger.current_value` | The current value for this Z-Wave value (translated to a state name when possible). |
| `trigger.current_value_raw` | The raw current value for this Z-Wave value (the key of the state when a state is named). |
## Current Limitations
- While support for the most common devices is working, some command classes are not yet (fully) implemented in Z-Wave JS. You can track the status [here](https://github.com/zwave-js/node-zwave-js/issues/6).
