HASP Node Name~
The Node Name is the unique identifier of your device on your MQTT Broker.
For example, setting the Node Name to plate35 will make the device listen and communicate on the main topic hasp/plate35/
The Group Name is the unique identifier for a Group of devices.
For example, the default Group Name is plates. This will make all devices in this group listen on the main topic hasp/plates/ This way you can send a command to all devices in the group at the same moment. Each devices will only respond on their own main Node Name topic.
