Concatenate Two variable strings

[dynamicdave]

As Craig suggested, I think you'll find you need to 'join' the two variables as although they are being generated continuously - they won't arrive or be processed by Node-RED simultaneously.

Take a look at this posting as it is very similar to your situation.

Select minimum of two values

Hi there, I am receiving two messages from mqtt, what I want to do is select the lesser of the two and output it to influxdb. I'm guessing I need to use a function but am unsure how to address two incoming message payloads inside the function. Can anyone please point me in the right direction? TIA
