ebusctl strings

[kue43]

Hi
Just had a Vaillant arotherm plus 12kw fitted and connected the ebus sheild C6.
It is using 08hmu and 15.700 csvs
I noticed I am getting quite a few data errors when there are values in them.
As an example,
Csv has IGN:4 and STR:5
Zone 1 name works but Zone 2 doesn't

Example using ebusctl hex and read:
ebusctl read -f -V Z1Name1
basv Z1Name1 value=Down [name of zone 1]
ebusctl hex -n 15b524020003001700
0903031700 446f776e00 = 'Down'

ebusctl read -f -V Z2Name1
ERR: invalid position in decode: basv Z2Name1
ebusctl hex -n 15b524020003011700
0703031700 557000 = 'Up' ; decode works with (STR:2 or 3 and NTS:2 or 3)

As you can see on zone2 name there are only 3 characters (2 characters plus null) returned and it wants 5 bytes so gives an error.
Can any one tell me how to get around this please.

1. Statt STR:5 lieber NTS:3 oder NTS:x verwenden
   Ändere die CSV-Zeile, z. B. in der Datei 15.700.csv, von:

Z2Name1;...;STR:5
zu:

Z2Name1;...;NTS:3
oder etwas großzügiger:

Z2Name1;...;NTS:5

Thanks, I did try NTS:5 but if I decode the 3 bytes it fails

ebusctl decode "nts:5" 557000
ERR: invalid position

It doesn't seem to like variable length strings.
If I use 2 or 3 then it works:-

ebusctl decode "nts:3" 557000
Up

The number in nts:X isn’t “string length” — it’s “maximum byte buffer size to read from”.
If you give fewer bytes than X, decoding fails.
