I'm happy since yesterday !
I installed node-red into my fanless W7 computer, installed related software (modbustcp) and connected it to my modbus plc, through its ip address and obtained 1 value
That means I will (future) be able to harvest data from my plc and integrate them into HE.
But I need more help here. it's about that integration, of course. MQTT broker, apps/drivers, etc.
If i have node-red working and harvesting data, what are the next steps to send them to HE ?
Just the basic rules of what to do will be enough for now, I'll dig into it later.
