:rabbit: myVaillant

Homey app that interacts with the myVaillant api that is normally used by the mobile app.
In theory all app features could be supported. But not all features are implemented, please add an issue or PR when features are missing for your use case.

:ok_hand: Tested

Tested configuration:

  • aroTherm plus vwl 75/6
  • uniTower plus VIH QW 190/6
  • sensoNet VR 921
  • sensoComfort VRC720

:heart: Credits

This Homey application leans heavy on the hard work of the following projects:

App store

Test release: myVaillant App for Homey | Homey
Source code is available: GitHub - PallieterVerhoeven/Homey-Vaillant-app: Homey app to connect with myVaillant api

Oh! That is great
Will try it ASAP
Is it published in the store?
Currently using it via Home Assistant (mypyllant)
Tried to make my own but never really gone more than “token obtained” stage

Thanks!

Just submitted the app for verification to publish it on the App store.
Last time they were quite fast in approving.
Expect to share the App store link tomorrow!

Test version is already available I see, because an earlier version was already approved😄
There is still one big limitation, it’s only available for dutch myVaillant accounts. Still have to add a country dropdown on the login page.

Sorry, I did not noticed it uses Dutch region.
Waiting for multi region updates.

If you need a tester for a other region (germany) let me know!

The test version should have support now for multiple countries: myVaillant | Homey.
Please let me know if it works :slight_smile:

Hi,

Keep up the good work!

Is this on the app > configuration/settings page? Got the same message, will add it to the list to fix.
I removed the logout button because it was not working yet, but forget to remove the listener for this button.

You should still be able to add devices, in the add new device flow it will ask to login if you’re not logged in.

OK, that worked. I can see my 2 thermostats now. Thanks.

I have different time programs with different temps but Homey is always shows 5° when in reality it is 21° now on the Vaillant thermostat.
When I change the temp in Homey to 20° the display of my Vaillant thermostat changes to 20° as a manual setting that overrules the actual time program. When I cancel that on the Vaillant thermostat the temp in Homey drops again to 5°.

I also have a outdoor sensor (buitenvoeler). Is it possible to read out that data?

regards,
Tim

Thanks for your feedback!
Can you share which products/model numbers you use?
I think I know where the 5° is coming from, this is the fixed frost protection value and is used in the Homey thermostat when there is no fixed temp or time program set. But maybe this reading is wrong.

Should add a logging feature to share the logs, it is quite difficult to debug without logs :stuck_out_tongue:

I have 2 VRC 700 thermostats & internetmodule VR921

Thanks, I see your heating mode is set to ‘AUTO’.
This is in my setup not an option, will debug to find how to read the correct set point temperature when the mode is set to AUTO.

Good afternoon,

Thank you very much for the application!!

I have tried with an installation from Spain and everything works correctly.

I will continue testing.
