multiple values on temp device

[haden]

Hi

I extract some data from my floorheating using node-red and publish to MQTT. I'm able to view and log the data, but I would like to modify the device to show some more status. The data I receive is: {"idx":5,"svalue":"18.43;19;0;2"} which are (actual temperature, set temperature, mode, program)
So how do I change the device to show the mode and program.?
I've just installed Domoticz (RPI) last week so are totally new to this universe. Are there any guides on how to edit this?

Thanks
