The device interface
Last Will and Testament message
The Last Will Testament (LWT) lets a client provide a testament along with its credentials when connecting to the broker. If the
client disconnects ungracefully at some point later (maybe because his power source died), it can let the broker deliver a message
to other clients. This LWT message has the same form as an ordinary message and gets routed via the same mechanics.
