EcoTec Plus VC20CS/1-5 PrEnergy* problem

[iszczyg]

Hello,
I've installed ebus adapter v.5 in Vaillant EcoTec boiler. It works perfectly. However, I have a question regarding the configuration (I was browsing the forum but without success). Almost all registers are read correctly. Unfortunately one group (PrEnergy*) returns the error (ERR: invalid position for...). I have found the sugestion, that my boiler has no such sensors. But I can read the energy consumption on the boiler lcd panel so I suspect that it has the sensors. Do you know what can be a reason for this? Thanks in advance for your help. I've planned to control the gas consumption with ebusd so this registers are quite important for me. Ebusd reports the bai.308523.inc config file
The output of ebusctl -find:
...

Hello, I have the exact same problem. Did you found out any solution?

Greetings

Hello,
Mentioned registers don't work. They probably do not exist - don't know why. However I've found workaround. Except of boiler I have also controller VRC 720/2. In the configuration directory (ebusd-configuration/latest/en/vaillant) I've created link 15.ctlv2.csv -> 15.700.csv. Now "ebusctl find" shows:
scan.08 = Vaillant;BAI00;0807;7603
scan.08 id = 21;22;31;0010024647;0001;010956;N7
scan.15 = Vaillant;CTLV2;0514;1104
scan.15 id = 21;22;13;0020260916;0953;016134;N8
Device 15 is VRC 720. There are a set of working registers corresponding to fuel and energy consumption:
'prEnergySumHc',
'prEnergySumHcLastMonth',
'prEnergySumHcThisMonth',
'prEnergySumHwc',
'prEnergySumHwcLastMonth',
'prEnergySumHwcThisMonth',
'prFuelSumHc',
'prFuelSumHcLastMonth',
'prFuelSumHcThisMonth',
'prFuelSumHwc',
'prFuelSumHwcLastMonth',
'prFuelSumHwcThisMonth',
The readout is in strange units but half year experience lead me to the coefficient which can be used to calculate m3 of gas consumption from the readouts: in my case it is 0.1034. The error is below 2%

Best regards

Thanks for your quick reply!
Great you found a workaround!

I will try this later.

[Dominik-1980]

Okay, you are reading these values from your smart thermostat.
I don't have such a device. I use tado, and tado has very little values it handles and no energy consumption over ebus.
Thanks you anyway!
I think the values are stored somewhere in bai, too. They just don't decode the right way...

@iszczyg @Dominik-1980 Have you found any solution? I have the same problem.
I have the same errors:

bai ProductionByte = (ERR: invalid position for 3108b509030d3e04 / 00)

How you resolve it? Could I please provide instructions on how to make link 15.ctlv2.csv -> 15.700.csv ?
