I do not want to change the tap water temperature. I am just looking for changing the CV (heating) water temperature, to stimulate the “stooklijn” based on the outside temp, without an outside Vaillant temperature sensor
I am using it every day to create a schedule when I want more hot water during certain periods of day and sometimes I am using Cylinder boost mode when arriving earlier at home.
It would just be great to have it, no push from my side! I appreciate your work.

Really great app :-). Thank you so much!
I own the following (Country Switzerland):
- Internet Module VR 940f
- Multimatic VRC 700/6
- ecoTEC exclusive VC 146/4-7 (Gas Heating from 2008 - pretty old
) - uniTower VIH R 200/5 F (Gas Boiler)
Somebody already mentioned it, but the “Current/Desired tap water temperature” for my gas boiler is missing. It should be possible to read it from VRC 700. What do you need from my side to troubleshoot?
Additionally for ZONE 1, there is a point “Luftfeuchtigkeit” (Humidity). My VRC 700 doesn’t support this with the integrated zone, so in theory you can remove that for ZONE 1 if it’s only the VRC 700. But that’s just a cosmetic point.
Hye, i tried mailing but it bounced.
When i use the card: set temp. it sets the temp but only for 8 hours.
Is this a bug? Becaus i want to set it to x temp till i change it manualy with the thermostat at home.
And when its on a timer it ignores the thermostat.
Hi, this app is great thank you!
A few questions:
Does the powerconsumption come vissable at the energie tab of the homey pro?
My setup has a waterboiler. Is it possible when it drops under certain temperatur to heat it?
And what does the warning empty tank mean?
Thanks allot!
@Pallieter thank you for this great app!! it’s really useful!
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!
I have a flexoCOMPACT exclusive heat pump VR 921
@semolex
Will add it to the list to change domestic water heating from the app.
The mode will be quite easy to add, the desired temperature is a bit more difficult because this will probably only work when you are in manual mode. So on change should it automaticlly change to manual mode or override the temperature for X hours?
@R5Turbo
Yes, the desired tap water temp is on the list to make it available from the app 
Good one, will remove this sensor when a VRC700 is detected. Thanks for your feedback.
@Yankee_Delta
Will have to look why it resets after 8 hours. The app does not define this. Could be because a time program is active that will overrule the changed temperature?
@Glenn_K
Added the device to the energy tab in the upcoming release 
The empty tank warning is triggered when the boiler temperature drops below 38 degrees (the shower will get cold).
@WouterV
Yes, not looked in to this yet. But saw some properties that should indicate when cooling is active. Will be added soon

No, the heating is on manual all the time.
Its like homey set the temp for 8 hours.
When i want to change it via the app i first need to stop set timer that homey put in.
and when i want to use the thermostat it just doesn’t allow it, before i stop the set timer from homey.
The other card when u can say that its need to stay at set temp works perfectly.
Thanks it works!! The empty tank warning goes indeed on under the 38 degrees. It would be great if that can be changed because my shower gets cold when its just 12 degrees tanktemp. My sensor is on the bottom but the water in the top of the tank is then still warm enough so i still can shower nice and warm 
Good one, was doubting to remove it because it depends on the boiler where the temperature is measured, mine is in the middle. And cold shower starts when the boiler temp is around 25 degrees. Will try to make this temp adjustable

Thank you for the app. I have two aroTHERM plus in cascade. Will they be visible in the future?
Since 3 days the Homey myVaillant Device doesn‘t update anymore. I‘ve nothing changed. Homey and the app has been restarted, no reaction… The nativ App from the vendor works, so it‘s not a general issue.
Finally, the only thing that worked was to repair the device.
Same here… repairing also does not work anymore. The input is 100% correct. Tried it on there own website.
Is there a maximum temperature for the actual boiler water temperature in the app?
After the legionella prevention program once a week, the hot water temperature is 72C in the Vaillant app. Is this app it doesn’t increase above 70C.
The app stopped updating. The device gives old data. Please help
don’t know if it helps but, when my normal network gives out, i just delete an add the devices again.
The repair function does not work.
Disclaimer you loose all of you’re previous data.
Yes indeed but then is al the data lost and then its useless.
Same problem here unfortunately. Other apps have an option ‘try to repair’ or something similar, then it lets you re-enter your credentials. That might be a solution.
Is there a way you can get Homey notify you when an app stops communicating?
Try to repair has this app also but mostly not fix the problem.
it has it but it does not work.
I delete and add evry week atm
