unipi1.1. evok to MQTT using Node-Red



  • I am using this NODE-RED flow to read all unipi data into my MQTT server.
    It initializes all states for my unipi control panel. Then it uses websocket for real time unipi events but with one exception.```
    1-wire sensors are read every 5 min (bulk request) which gives me better statistics and charts.
    I hope this will give interested persons some ideas but also I would appreciate suggestions to make it better.
