Hello, I have a tracker device that I have migrated to V3. Data are correctly arriving from my device into the TTN network as I can see them into the live data. I wish to transfer the data into a data base located in a linux device and for this, in V2 I was using MQTT and a pyhton script which is …

The message structure changed a bit in V3. I think u can find it here: https://www.thethingsindustries.com/docs/reference/data-formats/ Also the subscribe string should be different: [image] dynamitron: mqttc.subscribe('+/devices/+/up') It should be mqttc.subscribe(‘v3/+/devices/+/up’)
