I am trying to combine two output topic, payload pairs into an object made up of the payloads.
the two msg's come out of node-red-ramp-thermostat as topic = current / payload = value & topic = target / payload = value
I have tried using If statement approach on the topics but this seems a complicated / messy way of doing things. Is there a simple way to do this in a function. i need the output object to be msg,value = current payload, msg threshold=target payload.
maybe there is a node that already does this ? I have tried "join node" but cant get it to work, i would rather use a function if possable.

From your description, the Join node should be able to do what you want - or at least, it can do the work to get the two separate messages joined into one message. You would then need a Change node to get the different properties into exactly the form you want.
