Hi Svein,
The example code discussed in this topic is related to The Things Node and will only work with that device because of its onboard sensors.
If you want to have your device working on Cayenne to, make sure that it first works ‘normally’ with TTN, that it can join the network, and that it transmits regulary some sensor data.
Next step is to get that data to Cayenne.
Therefore you have to edit your code and set integration in your console.
