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.

[schlimmchen]

Yes, please, that is highly appreciated.

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?

Hi @SW-Niko,

sorry for my late response. Yes, I can confirm the FWE message represents the current FW version for my Victron MPPT 250|85 (identified as "SmartSolar MPPT VE.Can 250|85 rev2"). Firmware version is currently shown as "Firmware-Version: ." on the Live-View page.

This is the message I see in the "Konsole" log:
11:14:04.324 > [VE.Direct MPPT 34/-1] Unknown text data 'FWE' (value '315FF')

Thanks @ingrimsch,
it seems the Victron documentation is outdated or wrong.

Firmware version is currently shown as "Firmware-Version: ."

On your device Victron do not send "FW" Data. Now I understand why you want to process FWE.
How do you connect the CAN? Converter to UART?

@schlimmchen
How about to process FW and FWE. If FW is not available we use FWE and ignore the 2 last characters.

(value '315FF')

Means firmware 3.15
