Same for me also no data since 9 days
Hi there!
First of all i love that you created this app, iāve been waiting for so long to add my heatpump.
Unfortunately Iām experiencing the same issue of data not being updated anymore.
I hope youāll be able to fix it 
Thanks
@Pallieter
Fantastic news! I was waiting for the app like this. Could you please add support for Recovair ventilation system? Iām happy to test it.
He, in my app Iāve the same issue that data is not retrieved any more..
Will try to fix it as soon as possible, but I have a bit less spare time lately.
@guglez could you enable logging in the app setting and share the logging id with me. This will help me debugging what properties the Recovair system has in the API.

I shared the logging ID with you.
Are you using myPyllant library in the app? Iām using myPyllant with home assistant and Iām having issues with it - itās not updating the data shortly after you restart the app. I guess that vaillant cloud service temporary bans clients based on some criteria. I know how to intercept api calls from the iPhone app to their servers, not sure if that may help.
I was able to force renewing the connection: open the device (not app), go to settings (right corner), go to maintenance > try to repair > login.
That fixed it for me, at least temporarily.
I tried this aswell yesterday didnt work.
Tried again today and now it worked.
I selected netherlands in the login i have a feeling it has something to do with the login url perhaps.
Same issue here.
After device repair, the update works for ca. 24 hours. Than it stopped again. The error response in the action cards say āauthentication failed - 401ā. I would assume, that the authentication token from vaillant is expired and needs to be refreshed?
Is it possible to get flow temperature in the app also? Would be great.
Hi everyone,
Iām using a Homey Pro in combination with my Vaillant heating system (VR921 with Zones). Iām trying to control my air conditioning based on the indoor temperature measured by the heating system.
Hereās what I want to achieve:
- When the temperature is above 23Ā°C, the airco should turn on.
- When the temperature drops below 23Ā°C, the airco should turn off.
Iāve set this up using a flow that triggers when the temperature becomes higher than 23Ā°C. It works most of the time, but sometimes the trigger seems to be missed.
For example: if the temperature rises from 22.9Ā°C to 23.1Ā°C and the flow doesnāt trigger at that moment, it will stay above 23Ā°C without ever becoming higher againāso the flow never runs, and the airco stays off.
As far as I can tell, thereās no built-in way to trigger a flow when the temperature is (or stays) above or below a valueāonly when it becomes higher/lower.
Is there a workaround for this? Maybe using logic variables, a scheduled flow, or a script? Any tips or solutions would be greatly appreciated!
Thanks in advance 
here it runs for approx. a week, then values are not updated anymore. A repair and it works againā¦
Same but when log in with repair it shows that the credentials are not correct.
Iāve tried fixing the invalid token issue in version 1.7.3.
Hopefully this will fix the stale data.
@WimWeetjens
The trigger cardās you are using should be the best way to do this. My assumption is that the reason why this not always works is because of the current bug.
After a few days it the app often stops updating the realtime data that would also cause not triggering these zone temperature cards.

@Pallieter Awesome thank you!
It would be great if you could also add the status indicating whether the system is currently in cooling mode.
This would allow me to open the valves during the summer if the system is cooling instead of heating.
And if possible it would be great if you could also add the option to start manual cooling just like you do for heating!
same here, net to delete and install again
@Pallieter Sorry just found out i can read the status as COOLING so that is working nicely
@Pallieter so iāve found out that after a isp lose (no internet) it wont reconect.
Also repairing or rebooting the app wont work.
Only delting evrything and reconecting evrything.
Hi,
I have added a heatpump (but i dont have one). This way i could also receive the outside-temperature. This works perfectly, but i canāt select that temperature as info to put on the tile in the devicesscreen. Would this be easy to add? Otherwise ill try with a virtual thermostat
Ha all, hope someone can give me some advice.
I have a FlexoCompact 118/4 + VRC700/4 + now recently a VR9040f gateway module and the myVaillant app. Some of the app functionality is marginal, not sure why.
I have made in Homey a unit and a zone. The unit does not show all parameters correctly eg status does not change and power readings do not work. I do get outside temps and a water pressure. The zone only shows one temp, nothing about cooling vs heating. Auto day night settings give an error message status code 404.
Even though the correct unit (Flexocompact) and gateway are shown in the app (serial noās OK, no error message) I wonder if the system thinks it is a CV boiler instead of a heatpump. During first setup it showed a CV boiler, so I had to redo. I erased account, different mail address etc all from scratch and it seems OK but Homey is not showing correct data.
Anyone have similar problems? Any suggestions for cause and fix?
Update 11/7: Afterr contact with Vaillant customer service it could be that the gateway was a returned item and has been configured before on another system with a CV boiler. The Vaillant server may keep initial settings in spite of reconfiguring with a heat pump. This may explain the wrong readings and behaviour of the app.
Vaillant customer service will attempt to reset theis server settings though Vaillant HQ. If above is really what happened Vaillant has some homework so users have the option to completely 100% clear the server settings and start from scratch.
For now I will wait for Vaillant and hope this will resolve the issues.

Vaillant customer service at HQ has removed any refs in their database to a CV boiler.
The Vaillant app is working and showing energy use.
However on Homey I am not getting any power readings or water temp. I do get status, outside temps and system water pressure. I did remove the device, reinstalled it and after I did a repair.
The related zone is showing temp and humidity, but no option for cooling or heating.
Anyone have a suggestion? Am I doing something wrong?
