I have a Globallink 520 which is publishing data to the VRM portal. Is there a way to use MQTT to pull that data from VRM and then into my own system? I've looked at this guide, followed it, am able to login successfully, but see no data published (even with a keepalive message). Is there something I might be missing? Or, do I just need to use the VRM API using Python? Thanks in advance for any help.
