Issue with decoding PrEnergySumHc1 and other energy parameters

[mkalkowski83]

Dear Author,

I am experiencing issues with decoding several energy parameters using the ebusd-configuration, particularly the PrEnergySumHc1 parameter. When attempting to read this parameter from my Vaillant heating system, I'm consistently getting the error:

"ERR: invalid position in decode: bai PrEnergySumHwc1 [b5090dc500/]"

The same issue occurs with multiple other energy-related parameters like:
3108b509030df500 / 00 = 3: bai PrEnergySumHc1
3108b509030df600 / 00 = 2: bai PrEnergyCountHc1
3108b509030df700 / 00 = 2: bai PrEnergySumHc2
3108b509030df800 / 00 = 2: bai PrEnergyCountHc2
3108b509030df900 / 00 = 2: bai PrEnergySumHc3
3108b509030dfa00 / 00 = 2: bai PrEnergyCountHc3

but for the moment I would like to focus on the parameter PrEnergySumHwc1

below the result of the command grab result all:

Could you help me with this?

Probably these statistics don't work on your unit. This has been observed also for other boilers. I recommend trying the b516 energy statistics instead.

Here are some message definitions: john30/ebusd-configuration#490 (comment)

Complete description and details here: john30/ebusd-configuration#490 (comment)

As they were decoded only recently, they're not included in the main repo yet. There is a current PR though.

Great, thank you. I found comments that you mentored yesterday. I tested some of them and they work. I'm currently writing the configuration for my boiler. When I'm done, I'll prepare a PR with the changes. How do you guys get those hex values? Is there a way to debug what the ebus adapter is getting from the boiler? I'm trying to use the grab command, but it only returns information about what is currently defined in the loaded CSV configuration file.

Everything sent over ebus should appear in the ebusd logfile (I use log level 'notice').
