I just installed the newest beta and sadly no change.

Thanks for testing! At least the last error seems fixed now, but there’s a new one related to quick_veto_start_date_time. I have a testcase for parsing that. But your setup and in particular the dacite library I’m using seems to behave differently from mine (and the automated tests running on Github) - which is unexpected?

Just to be safe, I just spun up a new Home Assistant instance with my integration, and I’m not seeing that error with the quick veto set.

It would help if you could post the output of pip freeze | grep -i "dacite\|myPyllant\|homeassistant==" from your home assistant installation. It should be:

dacite==1.8.1
# Editable install with no version control (homeassistant==2023.10.1)
myPyllant==0.5.9

Sadly I can’t run that command on my HA system since I am running hassos…

Edit: For some reason it appears to be working now…I reinstalled the same version again (by accident) and now the entities are all there as far as I can tell. I will keep monitoring and see if it stays stable…

Edit2: Nope…it’s gone again.

willenic · October 9, 2023, 7:00am

Morning @pdd, thanks for a great integration which is actually give me some level of performance monitoring that would be otherwise unavailable out omy expensive arotherm plus.

I have a myVaillant Connect gateway, I can only see these services but can read data for Heating/HW/Zone 0…

So when I hit the boost button on the Hot Water control I get a message saying “can’t find url…” similarly on the Heating control. Is there anything I can do to automate my heating controls through HA?

pdd · October 9, 2023, 7:20am

@willenic you appear to be on an older version, try upgrading to 0.5.0 or later!

@CommanderROR I may be able to add some logging output down the line to investigate this further.

willenic · October 9, 2023, 6:53pm

Hey @pdd I upgraded to 0.5.1, lost connection to the 4 devices I had (arotherm +, Zone 0, Zone 1 and HW), I tried re-loading then deleted the hub account and signed in again to check. A bit stumped now.

Restored to version 0.4.0 from my last HA system back up and all connected again, will watch this space for updates.

pdd · October 9, 2023, 8:43pm

@willenic try the first beta of 0.5.0 (need to enable prerelases when redownloading) - that seems to be working for @CommanderROR at least. When you get a chance again to test the latest versions, I would appreciate if you could post logs. Otherwise I have nothing to go by and can’t really help.

willenic · October 9, 2023, 9:29pm

Will do, any specific search terms from the logs?

pdd · October 9, 2023, 9:43pm

mypyllant should give you everything, and then the error and its traceback (which you get by clicking on it).

willenic · October 10, 2023, 12:11pm

Bingo, 0.5.0b1, just used the Hot Water Control to raise the target temperature and boost the Hot Water… Thank you.

willenic · October 13, 2023, 9:08am

Hi All,

I’m trying to make use of the Water Heater: Set operation mode service to stick my hot water into Boost mode. I used the UI to generate the service call as below but it fails in the trace as it looks like the service isn’t expecting a device_id despite that being set as part of the automation UI? Any suggestions?

Edit: Still on 0.5.0b1
Edit 2: Tryed using entities of sensor.current_special_function_domestic_hot_water_255 and sensor.operation_mode_domestic_hot_water_255 without success too.

TIA

Will

- service: water_heater.set_operation_mode
  data:
    operation_mode: Cylinder Boost
  target:
    device_id: 35179c086d02f5c53a33bbd7097d6ef2

Trace issue

willenic · October 14, 2023, 9:46am

Hi @CommanderROR, how are you setting your Legionella cycle? Just by setting the temperature set point or are you changing the mode on the Hot Water device? Thanks.

CommanderROR · October 14, 2023, 9:58am

I am just increasing the temperature. In my case to 62°C on a specific day for a set amount of time. This seems more sensible than the 75°C Vaillant uses.

Gotilio · October 14, 2023, 11:48am

Hi @pdd,

The app that the Technician installed in my phone to control the system is called “Mi Control”, my gateway is the MILINKV3.

I try to login in your integration trying all the brand options and selecting may country (Spain), but it says my credentials are not correct.

So I tried to install the Vailliant APP and Mi GO App, created an account on both of them and logged correctly on your HACS integration, but when I try to add my device on that APPs in order to see my system info, it says the following message:

"Gateway Not Supported. Your installation in not ready to be controlled with this app yet. Please Return to your previous app (sensoApp or Multimatic app). "

Is something that I can do to connect to the MI CONTROL app?

Thanks a lot for all your work!

CommanderROR · October 14, 2023, 11:51am

You need to wait until your system has been moved over to the new Platform. There is nothing that can be done by the end user to speed up that process.

Gotilio · October 14, 2023, 2:18pm

@CommanderROR,
Thanks a lot for your answer.
I will wait until they “migrate” me to the new platform. I have read that is a normal and gradual process to improve the connectivity solution. Idea is to move everyone gradually in order to deprecate MiControl app.

willenic · October 14, 2023, 2:58pm

Thanks for confirming @CommanderROR.

@pdd should I be able to use the HW Control in an automation to change the mode of my HW?

I have an arotherm +. Ideally I’d like to be able to stick it into Cylinder boost at specific times of the day based on my energy tariff (which varies by 1/2 hour), likewise with the heating once the HW is sorted, but if I’m stuck with temperature controls so be it.

pdd · October 15, 2023, 3:08pm

@willenic setting modes should work, try building the service call in the UI by selecting an entity, not a device.

willenic · October 17, 2023, 10:56am

Success with the code below on v0.5.2 the entity of the device did the trick. Can switch between ‘Time Controlled’, ‘Cylinder Boost’ and presumably ‘Off’ if I wanted though haven’t got a need to test that.

service: water_heater.set_operation_mode
data:
  operation_mode: Time Controlled
target:
  entity_id: water_heater.domestic_hot_water_0

data:
  operation_mode: Cylinder Boost
target:
  entity_id: water_heater.domestic_hot_water_0

Entity Device

Hi All
Just wanted to give some feedback on the latest version of this integration.
I’ve been using the first beta of 0.5.0 for a few weeks and held off updating due to the issues reported by others in this thread. However, as of yesterday I’ve updated to the latest version (v0.5.2) and have had no issues in the last 24 hours. I’m using the integration to automate my central heating between Auto, Manual & Off as well as monitoring data for both heating and hot water.

Components:
aroTHERM plus
VR921 Gateway
SensoComfort 720
