read Timeout, CRC and ACK errors

[MobiD2017]

Hello,

After a full scan, I can find the following configuration:
address 00: master #1
address 03: master #11
address 08: slave #11, scanned "MF=Vaillant;ID=HMU00;SW=0305;HW=0403", loaded "vaillant/08.hmu.csv"
address 31: master #8, ebusd
address 36: slave #8, ebusd
address 52: slave, scanned "MF=Vaillant;ID=VR_70;SW=0109;HW=2903", loaded "vaillant/52.vr_70.csv"
address 71: master #9
address 76: slave #9, scanned "MF=Vaillant;ID=VWZ00;SW=0305;HW=0403"

My configuration is:
version: ebusd 3.1.v3.1-22-gdaf771e
update check: revision v3.1-1-g60a18d1 available, vaillant/08.hmu.csv: different version available
signal: acquired
symbol rate: 23
max symbol rate: 99
min arbitration micros: 5117
max arbitration micros: 7049
min symbol latency: 4
max symbol latency: 7
reconnects: 0
masters: 4
messages: 72

One Problem is:
from this side it looks good but if I try to read any data I got not from all answer:

hmu ConsumptionThisYear1 = (ERR: invalid position for 3108b516041a020100 / 00)
hmu ConsumptionTotal = no data stored

In to the Logfile I have the following message, but I'm not sure if it related to this problem:

2018-03-10 19:08:00.173 [bus debug] ERR: read timeout during receive command, switching to skip
2018-03-10 19:08:00.440 [bus debug] ERR: read timeout during receive command, switching to skip
2018-03-10 19:08:00.647 [bus debug] ERR: CRC error during receive command CRC, switching to receive command ACK
2018-03-10 19:08:00.653 [bus debug] ERR: ACK error during receive command ACK, switching to skip
2018-03-10 19:08:00.900 [bus debug] ERR: CRC error during receive command CRC, switching to receive command ACK
2018-03-10 19:08:00.906 [bus debug] ERR: ACK error during receive command ACK, switching to skip
2018-03-10 19:08:02.237 [bus debug] ERR: read timeout during receive command, switching to skip

the second problem is:

I'm not sure what is
address 71: master #9
address 76: slave #9, scanned "MF=Vaillant;ID=VWZ00;SW=0305;HW=0403"

best regards
Mirko

this is an ebusd-configuration issue rather than ebusd, but anyway:
it seems the HMU is not compatible to the CSV. this can happen with e.g. newer software versions in the device.
the debug logs are debug messages, so nothing to worry about.
for VWZ I don't know what this is.
