While the sketch connects to the mqtt broker and periodically sends its data, we need a way to identify the "plants" as we can have more then one plant. One way would be to leverage the mac address. This is unique, but not very human readable. The other way would be to use a coded id, which can be human readable, but has the risk of not being unique.
