My MPPT 250/85 sends an additional "FWE" message, that is also not processed yet. Example: [VE.Direct MPPT 34/-1] Unknown text data 'FWE' (value '315FF')

According to Victrons Protocol description this is the Firmware Version as 24Bit Value.

Citing https://www.victronenergy.com/upload/documents/VE.Direct-Protocol-3.33.pdf: "The firmware version of the device. The version contains up to 6 digits, 0 padding on the left side is not mandatory. Examples: 0208FF or 208FF for firmware version 2.08 (last digit FF indicates an official release), 020801 for firmware version 2.08-beta-01."
