Valliant Heatpump VWL xx/6 ebusd finds only a few values

[rivertechnology]

Hi, Thanks for all the good work and many information about the ebusd software. Unfortunately I only get a few values from my ebus.

Installed hardware: Heatpump: aroTHERM VWL75/6 (06.07) ControlUnit: VWZ AI (02.02) Thermostat: sensoCOMFORT VRC 720/2 (05.14) ERERA eBus Coupler USB at RPi4 buster

It seems that only vaillant/08.hmu.csv has been loaded, but i don't get many values.

Do I something wrong with my config? My /etc/default/ebusdebusd = EBUSD_OPTS="--scanconfig=full -d /dev/ttyUSB0 -p 8888 --httpport=8889 --htmlpath=/var/ebeus/html"

Or is there no config file available yet? Can I hulp with contribute on this issue?

Thanks in advance

-- Update!

For this type(s) op heatpumps @JongsmaSimon did an amazing job to create a .csv with all available data! https://github.com/john30/ebusd/discussions/720#discussioncomment-5520034

You can upload this file to your local folder and add the location to the /etc/default/ebusd config file: EBUSD_OPTS="--scanconfig=full --configpath=/home/pi/config/ebusd-configuration/ebusd-2.1.x/en -d ens:/dev/ttyUSB0 -p 8888 -l /var/log/ebusd.log --httpport=8889 --htmlpath=/var/ebusd/html

If you download the readall.sh file https://github.com/john30/ebusd/tree/master/contrib/scripts and run the script (./readall.sh), all data will be requested!

Hi,

Did you already find a solution? I have a simiilar issue. I have following devices, + 2 more that are not used address 08: slave #11, scanned "MF=Vaillant;ID=HMU01;SW=0306;HW=8802" address 15: slave #2, scanned "MF=Vaillant;ID=70000;SW=0209;HW=4103", loaded "vaillant/15.700.csv"

Sometimes the csv is loaded, sometimes not. most of the times it loaded for the HMU01 and i get data from it. today after a reboot of the heatpump i got the first time the csv for 7000 loaded and i seem to get data.

thats how my config looks like EBUSD_OPTS="--scanconfig --mqttint=/etc/ebusd/mqtt-hassio.cfg --mqtthost=192.168.0.17 --mqttport=1883 --mqttuser=USER --mqttpass=passwort --mqttjson"

[rivertechnology]

Hi,

Yes, I found a solution. But in your config I don't see any device configured like in my case an USB ebus device: --scanconfig=full -d /dev/ttyUSB0?

My thermostat: VRC720 was not recognized, so I manually cloned this configuration to /etc/ebusd : GitHub - janphkre/ebusd-configuration at feature/support-ctlv2

and added the local configpath the config

EBUSD_OPTS="--configpath=/etc/ebusd/ebusd-configuration/ebusd-2.1.x/en/ -d /dev/ttyUSB0 -p 8888 -l /var/log/ebusd.log --scanconfig=full --httpport=

then i got:

thanks for the quick answer, i loaded files now local as well, got a lot errors from broken files, removed them from the folder and now i run it with this config EBUSD_OPTS="--configpath=/etc/ebusd/ -d /dev/ttyUSB0 -p 8888 --scanconfig=full --mqttint=/etc/ebusd/mqtt-hassio.cfg --mqtthost=192.168.0.17 --mqttuser=user --mqttpass=pass --mqttjson"

but still it is not finding address 15

It anyhow only can find any address when i restart my heatpump. when the heatpump is running and i start ebusd or restart it, its not finding any address

i measuered 15v to 21v on the bus

[jkrauss82]

If I understand the conversation correctly, the observed issues might come from a suboptimal ebus adapter setup.

However, I would like to point to this related issue on the ebusd main repo: https://github.com/john30/ebusd/issues/437#issuecomment-947070000

The current CSV for Vaillant heatpumps in the ebusd-configuration repo does not deliver many values present in the CSV of the link above. I have tried that locally and got it to work with some adaptions (CSV contains template values such as "onoff", these have to be replaced by built-in types).

Anyone looking for more data from their VWL */6 I recommend to use this CSV.

[mf76130]

i am afraid that my 114€ esera adapter is not working as it needs for that system. i even tried placing to the VRC 700, to overcame the cable distance, but still not able to always find it. Lets wait on an answer from Esera Support

[mf76130]

stupid question, could the usb cable between the esera and the pi cause these issues as well? are there any special recommended cables

[jkrauss82]

As you already get some readings through the USB cable I would say it is highly unlikely that this is the issue here. But surely it does not hurt to try another cable either.

Have you checked your ebus wiring? I can imagine there could be problems if the connection is not done parallel for instance. Also check the voltage of the connection to your ebus adapter and at other devices and see if there is a difference.

[mf76130]

I am using 1,5mm² installation wire to connect the ebus adapter, not drilled, could that cause it? But thats only like 30cm long. I tried placing it parallel to the VRC 700, no change. I tried 3 different usb cables already (ordered possible better ones today) 2 of the 3 worked, one caused errors. Voltage is between 15V and 21V on the adapter, on the heatpump itself it is the same. I placed the VR920 i have behind the cabeling of the ebus adapter and that still works fine. I don't get it why that esera can be too slow, is the vaillant system the fastest on the market? :-)

[mf76130]

i got it working now, i am using local files and have only the needed files local available and did remove scanconfig from the configuration. best, you don't need to restart the heatpump anymore, just the ebusd service.

Thanks for sharing this file. Fantastic work to make it possible to read all the info from the heatpump. Can you explain how I can tell ebusd to load this file? I've tried to replace my current 08.hmu.csv file with the files of yours, but I don't get it to work.

[mf76130]

starting ebusctl yourconfig --checkconfig will show you the errors, then you can work on it

[rivertechnology]

Thanks for the quick answer. For me it's hard to understand and to use the ebusd commands. After trying to read the wiki as good as possible I'm still not understand the command you suggest.

This is my ebusd config: EBUSD_OPTS="--scanconfig --configpath=/home/pi/config/ebusd-configuration/ebusd-2.1.x/en -d /dev/ttyUSB0 --latency=20000 -p 8888 -l /var/log/ebusd.log --httpport=8889 --htmlpath=/var/ebusd/html"

I've uploaded the 08.hmu00.csv file at the /home/.../en config folder

After a ebusd service restart 'ebusctl info' shows

address 03: master #11
address 08: slave #11, scanned "MF=Vaillant;ID=HMU00;SW=0607;HW=5103"
address 10: master #2
address 15: slave #2, scanned "MF=Vaillant;ID=CTLV2;SW=0514;HW=1104", loaded "vaillant/15.ctlv2.csv"
address 31: master #8, ebusd
address 36: slave #8, ebusd

When i delete the 08.hmu00.csv file and restart ebusd I get:

address 08: slave #11, scanned "MF=Vaillant;ID=HMU00;SW=0607;HW=5103", loaded "vaillant/08.hmu.csv"
address 10: master #2
address 15: slave #2, scanned "MF=Vaillant;ID=CTLV2;SW=0514;HW=1104", loaded "vaillant/15.ctlv2.csv"
address 31: master #8, ebusd
address 36: slave #8, ebusd

My questions is that I don't understand ebusd don't want to load the HMU00 configfile and how can I ebusd forces to load the this file?

[mf76130]

try it without --scanconfig, then it loads all files automatic, but you won't see it next to the devices, but when the device appears later it still uses the csv files.

[rivertechnology]

Result at ebusctl info:

[john30]

ebusd 22.4 is out and it continues to try scanning devices until successful, maybe that helps

[jkrauss82]

I just found that for the VWL 75/6 the definitions for item CurrentCompressorUtil in the shipped 08.hmu.csv have to be adjusted slightly for datatype: instead of D1B it needs to be D2C.

I am still learning how to figure out the correct definitions but made some progress today. I hope to eventually be able to produce a combined version for the hmu00 from Yunkie's file and the current shipped csv, would create a pull request then.

[TheJokerHA]

Hi,

I have also an VWL 75/6 from Vaillant and looking for more useful data that I can use (consumption and so on). I just get this read out via MQTT and no consumption is received!

Ebusd is running on my Qnap NAS as an container!

-scanconfig -d tcp:192.168.1.97:5000 --mqtthost=192.168.1.47 --mqttport=1883

Will consumption be integrated in a new john30/ebusd version, I have the latest at the moment v22.4.

[bknoors]

Hi, I have the following setup: VWL75/6 A 230V [scan.08 = Vaillant;HMU00;0607;5103] VWZ MEH 97/6 [scan.76 = Vaillant;VWZIO;0607;5103] VRC720 [scan.15 = Vaillant;CTLV2;0514;1104]

To get this to work I adjusted some data types (mainly from EXP to UIN) for the HMU00, so this file might be useful: 08.hmu00.csv

Also minor changes to the 15.700.csv (and change of name to work with VRC720) 15.ctlv2.csv

Thanks for the great work, very happy with all the data!

BK

[karusell]

Hello, does anyone also have csv file for VWZ MEH 97/6? address 76: slave #9, scanned "MF=Vaillant;ID=VWZIO;SW=0202;HW=0103"

Whould be great to have transformation file csv for that, because there are some parameters which I need for further use.

Thank you.

[JongsmaSimon]

a new 08.hmu.csv (English version) has been finalized by me. It works for Vaillant Arotherm Plus 125/6 and similar heat pumps. It makes available all info visible in the VWZ AI+ menu. If you are using a thermostat (besides VWZ AI+) not all entries in this csv will return a valid value (these will be accessible via the thermostat csv file). This csv also contains three 'write' entries that will (when uncommented) enable changes to be made directly from the Home Assistant UI.

I have applied two files to my system: 08.hmu.csv (en) 15.ctlv2.csv Both are working. However I do not see the any good readouts or nothing from my VWZ MEH 97/6 (address 76). What is the proper file? Any to share it to me?

Which device is the ec.sol.sc.csv? Is this file correct (original file from repository)?

I have a similar setup. Did you get it working ?

Yes it is working perfectly. Of course I need time to get it running after reading such posts (Tweakers.net - Verwarming uitlezen met ebus - https://gathering.tweakers.net/forum/list_messages/2174564) / update xls files several times.

Hereby my backup of current files/folders. There is also a readme.txt. I am not sure if this readme is up to date. I think so.
