I finally managed to get my gateway connected and also connect/reuse an old node. I am now trying to write a decoder to get useful data out of the payload. The sensor that i current have connect to the application is a temperature sensor with channels. It actually measure 2 temperature at the same time and sends out the data either after 1 hour or after clicking the button.
The change that i am currently facing is that i have noticed that there are 2 payloads:
The application view,
The gateway view
The issue is that the payload shown in instance 1, doesn’t change when the temperature changes, but the payload in instance 2 does change when the temperature changes. That is why i am assuming that the payload shown in instance 2 (gateway view) is the right payload.
Can somebody perhaps explain what the difference is between the two payloads and why they are so different from each other?
The second Challenge I am facing is that I don’t know how the temperature is computed, meaning i don’t know in which byte (or combination of bytes) the temperature is in. I am now trying to figure out, by trial and error (recomputing known temperatures, like body temperature), which byte(s) are showing the known temperature.
Does anybody know a more effective and efficient way? All the help is much appreciate it.
