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."

Hello @ingrimsch ,
I have a question regarding the "FWE" message.
According the documentation (VE.Direct-Protocol-3.33.pdf) from Victron: "FWE" is for "Phoenix Charger" and "Smart BuckBoost" only.

Can you verify again?

Hello @schlimmchen ,
regarding the "RELAY" message. I can implement the missing functions, (web view, MTTQ and HASS) in the same way like the "IR" / "LOAD" messages, if you like.

Yes, please, that is highly appreciated.
