This service can be used in tandem with the node status sensor (disabled by default) to track the node's status and fire the command when needed. Here's an example automation that would ping a node when the node status sensor state has changed to dead and remained dead for 30 minutes. Note that this may be useful for some devices but will definitely not be useful for all. In cases where it is not useful, all you will be doing is generating additional traffic on your Z-Wave network which could slow down communication.

## Current Limitations
As this integration is still in the early stages there are some important limitations to be aware of.
- 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).
- There currently is no migration path available from any of the other Z-Wave implementations in Home Assistant. Your Z-Wave network is however stored on your stick so migrating will only require you to redo your device and entity naming.

Some legacy devices don't report all their values automatically and require polling to get updated values when controlled manually. Z-Wave JS does not automatically poll devices on a regular basis without user interaction. Polling can quickly lead to network congestion and should be used very sparingly and only where necessary.
- In an upcoming release of Home Assistant we will provide a service to allow you to manually poll a value, for example from an automation that only polls a device when there is motion in that same room. If you **really** need polling, you can enable this in zwavejs2mqtt but not in the official add-on.
- We provide a `zwave_js.refresh_value` service to allow you to manually poll a value, for example from an automation that only polls a device when there is motion in that same room. If you **really** need polling, you can enable this in zwavejs2mqtt but not in the official add-on.
- zwavejs2mqtt allows you to configure scheduled polling on a per-value basis, which you can use to keep certain values updated. It also allows you to poll individual values on-demand from your automations, which should be preferred over blindly polling all the time if possible.
