Khomp NIT21LI and Tago dashboard (default)

@Andre Antivilo

Hi, I am trying to connect and see data from a Khomp NIT21LI endpoint using LoRaWAN Everynet network. I’m using NLT, and the network is running fine. The problem is that I don’t know how to decrypt the payload!

I’m using the default payload parser for LoRaWAN from Tago with a little modification:

// Search the payload variable in the payload global variable. It's contents is always [ { variable, value...}, {variable, value...} ...]
const payload_raw = payload.find(x => x.variable === 'payload_raw' || x.variable === 'payload' || x.variable === 'data' || x.variable === 'encrypted_payload');

But I can’t see temperature, humidity and battery voltage variables. Any suggestion?
