VWL 75/6 with MEH 97/6 an VRC720 missing functions

[kecksk0enig]

Hi is there a possibility to tchange the water Heating mode from Normal to Eco via homeassistant/mqtt?
currently i am unable to read/write the according property. I would like to switch the water heating mode accoring to the outside temperature (ECO mode only when temp is above threshold, else use normal heating mode)

I am able to set the mode on the MEH97/6 from withn Fachhandwerkereben but not via ebus.

thank you in advance!

If you send ebusd/720/OpMode/set and value 2 what happens?
You can be limited by default filter-direction = r|u in mqtt-hassio.csv it makes it read-only.

Thanks for the reply. i run ebusd from a docker container, passing --mqttvar="filter-direction=r|u|^w along the docker CL

root@529fe758fccb:/# ebusctl f hwc
broadcast hwcStatus = no data stored
ctlv2 HwcFlowTemp = 0.0
ctlv2 HwcLockTime = 90
ctlv2 HwcMaxFlowTempDesired = 55
ctlv2 HwcOpMode = auto

ctlv2 HwcSFMode = auto
ctlv2 HwcStorageTemp = 43
ctlv2 HwcTempDesired = 43
ctlv2 PrEnergySumHwc = 903
ctlv2 PrEnergySumHwcLastMonth = 94
ctlv2 PrEnergySumHwcThisMonth = 100

toggling between ECO and balanced @ the MEH97/6 did not change any of the beforementioned properties

It is strange tat you load 15.ctlv2.csv instead of 15.720.csv, but ok.
Then according your results you have configured only one zone and should operate on that mode:
ebusd/cltv2/z1OpMode/set

hm why would the hotwater be controlled by z1? id assume something like hwcopmode. also the value uf z1OPmode did not change at all when I switch the hotwater mode @ the MEH97/6

[Koky05]

Sorry, my mistake. I was in that we are talking about heating.
ebusd/cltv2/HwcOpMode/set

[kecksk0enig]

As statet above. the value of ebusd/cltv2/HwcOpMode does not change when setting the value on the MEH97/6.
also if i change it with ebusctl w -c ctlv2 HwcOpMode 1 or 2 or 3 the value observed in Fachhandwerkerebene wont change at all.

This is still an open question. any suggestions to solve this are appreciated!
