Vaillant Live Monitor, found correct values, need help creating config #167

Open AleXburnA opened 4 years ago

AleXburnA commented 4 years ago

Dear all,

I am using ebusd with a Vaillant VWL 85/3, Unitower and VRC720. I am pretty new to this at all but as far as I understood, there is currently no configuration available to read the values which are shown in the Vaillant "Live Monitor". In my particular case this is:

Other values like temperatures, status, etc.. are working fine and I am already using it with iobroker. It's just the missing (and for me very interesting) values shown in the Vaillant "Live Monitor".

In order to gather the correct hex values, I did a "ebusctl grab", entered the Live Monitor on the Unitower and noted the shown values. After that, I exported the results with "ebusctl grab result decode" and searched for the previously shown values. I did that multiple times to double-check my results.

Now I am at the point where I am stuck. I'd like to add this to the corresponding csvs but I really don't understand how to achieve this. I have read the wiki but I didn't quite understand the message syntax. (I am not a programmer and have only basic experience with hex codes)

On the picture shown below, I think I found the current compressor modulation (52% was shown in the live monitor) image The hex value in the screenshot is: 7108b51a0405163225 / 0a16081b34000000000000

I have checked my result with another file , this time the compressor modulation was 70% shown in the live monitor. image The hex value in the screenshot is: 7108b51a0405cc3225 / 0acc081b46000000000000

I guess this could be the right message which contains the compressor utilization as big parts of both hex values looks the same and both have the correct values in it. Unfortunately I don't have any clue how to get further :)

Could someone please help me to transfer this finding to the configuration? In my case, 08.hmu.csv is loaded

I have similar findings for the other values as well.

Best regards Alex

Here are even more values:

1.) Heat gained from air (Kälteleistung) In this example, 5,3 KW was shown in the live monitor: image Raw hex value: 7108b51a0405f13223 / 0af1083535000000000000

And here, 5,0 KW was shown at the live monitor: image Raw hex value: 7108b51a04051b3223 / 0a1b083532000000000000

2.) Current power consumption:

Here, 1,6 KW was shown at the live monitor: image Raw hex value: 7108b51a04052c3224 / 0a2c083510000000000000

Next example, 2,0 KW was shown in the live monitor: image Raw hex value: 7108b51a0405013224 / 0a01083514000000000000

Best regards Alex

Got it working after many many hours of digging. Now I have to learn how to create a pull request :-)

Hi, I'm looking for something similar for a Vaillant flexotherm. There is data on the live monitor which I need to troubleshoot my system. It's not clear to me how you convinced the heating system to send this data over ebus. If I go into the live monitor nothing is sent to the ebus. Did you find additional values? and how does your final csv look like? Many people are looking for such data and you got very close to the date they need. Well done ;-)

Hi @joergensen70

suitable for the new heating season, I finally found the time to figure out how to create a pull request. You can find my csv there:

https://github.com/john30/ebusd-configuration/pull/194/commits/6f9249a94005844ac65cc5d49fe2b87e8a50a247

And yes, I was able to grab those values just by opening the live monitor. I mean, the ebus is the only way how the outside unit can send its data to the inside controller, so it has to go over it. The hard thing for me was to figure out how to put it into the csv.

hi @AleXburnA i have a vrc 720 with a vaillant 115/2 heat pump for cooling too ... i'm able (thanks at all contribution ) to read some values;

i really like to read (and can't) :

could you help me ? or teach me how can grab this command and decode ? Regards

Hi @AleXburnA, my values for Compressor Modulation range from around -110 to 120%. Did you ever expect such behavior?

Regards

i really like to read (and can't) :

  • Humidy
  • read and write timer ( for cooling and heating )
  • read and write cooling start and end date

could you help me ? or teach me how can grab this command and decode ? Regards

Did you find a solution to do set the cooling start and end date @AleXburnA @gibbo520 ?
