I've installed a node-red into a Windows 7 computer and it's running from the start with different flows (from my modbus plc's). Also connected to a cloud mqtt broker. Ok, fine.
Next step: install a local mqtt broker to bypass the cloud. Should run on Windows computer (for now). Any name ? Mosquitto ? Another one ?
And do you also know an android app able to connect a cloud/local mqtt broker aswell ?
