Yea i figured that…
Someone said “you can get that data via MQTT”… implying “log data”?..
Which you can’t. At least not a lot of it - if any at all. We don’t know what the log file stores.
But the whole MQTT subject (as is the FW side conversation) is quite far “off topic” with respect to the original question if at all. 
Log files in various systems are not normally kept very secret. But if the log files here tell Bambu all kinds of data that gives them a competitive advantage - then i’m not surprised it’s encrypted.
