I am using a Multitech device which acts as LoraWAN server. Elsys.se sensors are connected fine and are delivering data.
Now I have the problem in node-red the payload data does not look like useful data. E. g. the CO2 sensor's payload is sometimes: payload": [ 5, 1 ]
I read about decryptors online, but those I found (also on elsys.se website) did not work. Please note I am new to Node-Red and LoraWAN, so please be kind and be a bit more elaborate, thank you.
This is the current flow for it (so far only two switches are included which sort the data and add the topics for each of the own sensors to the data, so I can act on it):
