MF=Vaillant fails to parse answer: scan config 76: ERR: invalid position

[grafenam]

This topic was raised in other discussions, but resolutions where not working for me.

I just received my ebusd adapter 3 and now I am trying since hours to connect my Vaillant VWF 88/4 + VRC700/5 and VR920 to it.

Is it possible to get the scan working properly?

I've found the solution here https://github.com/john30/ebusd/wiki/HowTos#creating-new-message-definition-files

@grafenam Did you find a configuration for the device with id 76 (VWZ00)? Would be fine, if you could share it...

Thanks!

[grafenam]

no, i started to debug. Do you have the same issue?

[mwildbolz]

Same issue on my side, also with exact same HW and SW version...

[grafenam]

I'm still not able to find the right configuration. Any idea if a newer SW version could be provided by Vaillant?

I dont think that a never software from vaillant could solve this. We have to create a fitting csv for this device. By the way I am in a similar situation address 76: slave #9, scanned "MF=Vaillant;ID=VWZ00;SW=0308;HW=0403"

[grafenam]

It seems other users had this issue too: https://github.com/john30/ebusd/issues/379#issuecomment-757459644 Anyone able to share the 76.vwz.csv file?

I have same issue: address 76: slave #9, scanned "MF=Vaillant;ID=VWZ00;SW=0308;HW=0403"
