Decoding protobuf in Node-Red or Python

Hi All!

Firstly, thanks for all the work and effort already made to this awesome project.
I currently using the serial_interface.py for communicating with the Heltec devices I am running here, and works quite well. Is there a full doc on the serial_interface?
I am getting packets fine under msh/1/c/“deviceID”. So it seems to be the encrypted version of the protobuf? I tried the protobuf decoder in node-red and pointed to the mesh.proto file under the Meshtastic-protobufs repo, but get a type error.
I could also run a python script, but would need to get a hint in the right direction as my programming skills not high enough seems like. Any help would be much appreciated!
Thx
Rainer

Looks like this link rotted, I was about to try the same thing - did it point towards anything interesting?
