This time the integration of ESP8266 and the Node-RED platform was realized integrating a sensor DS18B20 of Protocol of Temperature Onewire.
From an HMI or SCADA Web creator on Node-Red-Dashboard using as base the MQTT Protocol and pubsubclient library converting the ESP8266 into MQTT Client.

Step 4: Images Node RED
According to the tests performed, the MQTT protocol is very fast,
allowing communication between Node-RED and ESP8266 to be almost in real time. From certain protocols we have tested, we consider and recommend implementing the MQTT for your IoT projects
