++All data is published to the MQTT topics. if you want to store/get the data, you would have to create an MQTT handler and store the data yourself.
++This example will be shown how to store/get all the data in two ways:

++
++

++
++
++**//2). MQTT  Sub//**
++
++If you don't want to store the information via node-red, you can get the output via the subscribe command.
++
++
++**If connecting from the same machine, you can use the following command to receive data:**
