Siemens IOT2020 - installing and testing Node-Red, MQTT and SQLITE3 HD
Time to install some software to allow us to build a real open source industrial Gateway This to me means Node-Red for control flows to be designed and managed graphically MQTT for publishing commands and data and also for subscribing to edge node information SQLITE3 to allow historical data to be stored and retrieved for trending and analysis Now before we can install any of this you will have had to follow the first few videos Creating SD Card :- https://www.youtube.com/watch?v=QLZ7fdTBYeQ&index=3&list=PL_atu5RtEPi72ubTe0c7rr1xJWhBSXted Expanding File system to make full use of SD card https://www.youtube.com/watch?v=DVRZ7fX86Io&index=4&list=PL_atu5RtEPi72ubTe0c7rr1xJWhBSXted Now we will configure Data Sources, Architecture and then install Node-Red, MQTT in the form of Mosquitto and SQLITE3 for database functionality Then we will add many Node-Red modules allowing Node-Red to use them. We will also add nodes for Modbus, GPIO, Serial and other features like talking to ESP8266 edge modules.
