Allow MQTT connection with Last Will Testament LWT. I found using LWT to determine whether device is connected or not more convenient than using current heartbeat monitor. LWT setup can be done using the web interface by setting the LWT topic and message. If LWT topic is left blank then MQTT connection will proceed as per usual.
