Mqtt Last Will and Testament use on Project

[FilipeCarvalhedo]

Hi, I'm using the zwave-js to control some devices and I need a way to know if the gateway is offline. I have researched a little bit how to do it with mqtt and I found out the Last Will and Testament. Does this project have something similar?

Sure, lastWill testament topic is:

<mqtt_prefix>/_EVENTS_/ZWAVE_GATEWAY-<mqtt_name>

Payload:

{
  "value": false
}
