Where did you find this? I am using the current versions of the web UIflow(V 1.9.0), and the Desktop version(V 1.7.5) for Mac, but I only find the old version. I would very much like to have a second Mqtt client running.
Ohhhh, I see it's for the Ethernet MQTT unit. Does anyone know how I could have a second instance of MQTT on a core2 using UIflow?
