Ok – I will look into those clients. I started and got working the Paho MQTT C/++ library and seems to be very reliable. Its pretty feature rich with means it won’t work on the smaller platforms most likely.
I need to add a couple options to the UI config screen and to get a feel for how this will work I have also submitted “part” of the first push request, to bind the raspberry PI interface to Local Host only. Option only shows up for RPI.
I was able to download the UI.zip file and run it locally and get things working fine to add one new option o52, hlh – for Http Local Host Only. I have not been able to find the UI code aartificats on GitHub. How do I contribute those changes back?
In the mean time, the option works great on the raspberry pi and is disabled on other platforms.
