Gateway: Node-RED + ESP8266 Modbus RTU MQTT + HMI Industrial Panasonic: Given the growth of IoT applications using the MQTT protocol as a base and the Node-RED platform, we have created a possibility for industrial devices or devices using Modbus RTU protocol (RS232 or RS485) to interact with applications or IoT platf. The Android app will send request to the Raspberry Pi which will be connected to smart energy meter. But there are issues when I am reading values. This project started some time ago when I became interested in renewable energy and built a wind turbine, and since then has evolved into a self-sufficient solar energy system, reporting real energy data to the internet using a Raspberry Pi. However, their capabilities and flexibility are still largely under estimated in the industrial environment. P from Carlo Gavazzi is a Type EM24 DIN energy management energy analyzer. To indicate the user like power theft, over power usage, instantaneous power, and total energy usage will be given by raspberry pi controller by speech and display indication will be done by raspberry pi, this method really helps the. This PRO1 model supports Modbus. Building energy monitoring use-case Monitoring (commercial) building energy is a typical IoT use-case, yet an optimum solution is still not obvious.
