Field Definition: Slave Byte Offset?

[knalltuete86]

Dear all,

currently I'm trying to decode some messages from Vaillant VWZ 76. I was already succesfull for one field:

1076b5110101 / 09ff40a016ff650000ff

In this example the Slave message contains the displayed Outside Temperature at Byte 4 (0x16 = 22°C).

For this I tried to create a 76.vwz.csv in my Config-Folder which is loaded correctly:

r,vwz,DisplayedOutsideTemp,Außentemperatur,,76,B511,01,,,tempv,,,Außentemperatur

(I just took a copy of the same value from 15.700.csv and adjusted the ZZ, PBSB and ID).

But the result is wrong.

ebusctl read -c vwz DisplayedOutsideTemp
1.34566e-24

I guess this is because of the wrong Byte is decoded.

How can I set the Byte to decode in Field Config? I could not figured it by the examples made.

Regards
