Owl Intuition SolarPV - multicast reader
Using a Raspberry Pi, Node Red, Influx & Grafana, and Owl Intuition PV
This flow currently reads a string from the multicast sent from an Owl Intuition SolarPV broadcast. (I'm also about to add the electricity and weather packets from the Owl broadcast).
It selects the data packet for the solar panel, and creates global variables for 6 items: 1/ SolarPV id, 2/ timestamp, 3/ the watts currently being generated by the panel, 4/ the watts currently being exported to the national electricity grid, 5/ the daily wattage generated and finally 6/ the daily wattage exported to the national electricity grid.
The six global variables are combined and sent as one payload to an influx database called OwlSolarPV.
Using grafana to graph the output, but there is also the opportunity to graph/chart the outputs to the node red dashboard.
