Home Assistant's MQTT integration supports so-called Birth and Last Will and Testament (LWT) messages. The former is used to send a message after the service has started, and the latter is used to notify other clients about a disconnected client. Please note that the LWT message will be sent both in case of a clean (e.g. Home Asisstant shutting down) and in case of an unclean (e.g. Home Assistant crashing or losing its network connection) disconnect.

Where a device doesn't send updates on status changes to the controller, you can work around this by using a thing called Polling. That causes the controller to ask the device to provide an update on all its sensors and states. This will cause a lot of traffic on the network, and if you poll too many devices too quickly, you can effectively break your Z-Wave network. Polling should only be used where there is no other choice, and you should use as large a polling interval as possible. Ideally you should replace the device.
|
||||
|
||||
For example, with `polling_interval=60000` (which is the default) if you have 10 devices that are being polled at every interval, and each polling takes one secound (request/response round trip), then it will take 10 seconds to complete the polling list. This only leaves 50 seconds left for normal traffic. The more devices you poll, and the shorter the interval, the less bandwidth that's available for normal traffic.

Polling needs to be enabled per device, you can control this through the *polling intensity* (interval) of the device. See the [Node Management](/docs/z-wave/control-panel#z-wave-node-management) documentation for details.

The chance is very high that this is not a bug but an issue with the service/daemon itself. Check your network (DNS, DHCP, uplink, etc.) first and make sure that Home Assistant and the service are poperly configured. Keep in mind that webservices can be down.
