Hi Adrian,
Please install MQTT.? ? I am using Eclipse Mosquitto MQTT in a docker container, but this site has the installation instructions for a bare metal install too.
I'll look through my backups to see if I have a pre-mqtt HRD flow that I can also share.? ?That said, if you install MQTT, it will make future projects easier.? ? This HRD flow is part of an amplifier project and none of the systems are running on the same server.? ? ?MQTT and NodeRed are in docker on a linux server.? ?The amplifier has ESP32 MCUs that read voltages and publish to MQTT, and my desktop runs HRD.? ? ?
When it's properly installed, all the MQTT symbols will display as "connected".? ?
