Can someone please advise on how to get relevant info back from ttn?  
I am sending temperature and humidity from Adruino with DHT11  
Com port monitor:  
Temperature: 3000  
Humidity: 4900  
Sending: mac tx uncnf 1 0BB81324  
Successful transmission  
– LOOP  
How do I get this Hex back into something meaningful via MQTT as the node-red debug with # as the Topic shows time, date, led state, ID and just about everything except the temperature and humidity readings.  
I’m sorry this is a bit of a basic beginers request but cannot find information required to progress.  
Thanks in advance  
Bob
