System time
No system time on app on my iPhone (or way of changing it) and the system time keeps jumping ahead by one hour to CEDT. This after setting DST to Automatic so I’ve gone back to manual. Is this a known bug?
Needs work
Vaillant VRC 720 and myVAILLANT app: assessment
*** The priority for improvement ****
Realtime Temperature readings with zero cloud delay.
Realtime measured energy information rather than algorithmic estimates presented as consumption figures.
1. Local heating control
The VRC 720 provides local accurate heating control independently of the app interface.
In practice, the controller can be clunky to switch on, plastic button, not touch screen access, and it’s slow to load data - should be instant.
2. Room-temperature readings
The app relies on a communication path involving the gateway and Vaillant Cloud.
Delayed updates can cause the app to show an older temperature than the controller currently measures.
Users should not have to guess whether a displayed temperature is current.
3. Energy consumption, yields and efficiency
The app explicitly warns:
“Energy consumption, energy yields and efficiencies are extrapolated based on various parameters. The actual figures may differ substantially in some cases.”
These are algorithmically extrapolated figures, not actual measured energy consumption. They should not be presented in a way that encourages users to treat them as accurate, real-time measurements.
Overall verdict
The local controller and the remote monitoring app should be judged separately. The controller performs the core heating-control function, while the app’s usefulness is undermined by potentially stale temperature data and energy figures that differ from reality.

Update
Been using the app as a heating and hot water controller very successfully for quite a while now. When it’s working, it’s very good. Had trouble reconnecting after a broadband router change, but all sorted eventually.
Backwards moves
Despite promises a timed heating option would return (switch on and off on an ad hoc
Basis for a period of time) and be sorted - as we approach Winter - NOTHING HAS CHANGED!!!
Time app developers worked with consumers so you know, apps could be useful and not waste energy (given the enormous cost of it)
—-
I see despite the company “investigating” the below - nothing has been done to bring this option back.
I am wasting money and energy because a really useful feature was ripped out of the app for no reason whatsoever!
—-
Overall - excellent app and controls
BUT removing the option to set the heating for a set period of time under manual settings in the app is really silly (timer function)
It means I end up using more gas - wasting money and energy!
What a ridiculous thing to do.
Bring that option back!

A most esoteric app
As a novice user of a new ASHP, this app seems to purposely make it difficult to find out anything useful. I’m used to the, kind of, ok Hive app with my old gas boiler but this new app gives me no useful information without me reading a manual. Okay, so I can check my system pressure, but I can’t check historical temperature values. I’m not even sure that I can tell if the heat pump is actually running, when it started running and what a forecast of energy consumption might be. The ambiguous glowing display might mean that it’s running; who knows? Needs a big UI upgrade and simplification. A bit of text might help. I’m likely being over critical, but having to consider integrating it into home assistant just to find out how it’s working seems a bit much.

Been using the app as a heating and hot water controller very successfully for quite a while now. When it’s working, it’s very good. Have just, however, had a fairly catastrophic issue in the shape of a new broadband provider and router. Resetting the system and reconnecting, I have just been advised by Vaillant tech support, is (with my set up) an engineer call out. OUCH!!!

Absolutely love

Really good
Works a treat
Update
Been using the App for a while now so very quick update. Remains very good if not the slickest UI. I have a request: The heating and hot water setting temperatures are periodically replaced by leaf icons in the app display. Presumably some sort it algorithmic pat on the back? This is incredibly annoying. I don’t want to know what a leaf looks like; I want to know the temperature settings! Please can you remove this piece of over-design. Thank you.

Good when it’s working
Good when it’s working but it keeps dropping out from the router and router is only 10 meters away
No support for Google Home?
Very disappointed that there is no support for integration with Google Home
Mrs
I absolutely would recommend having one.
It takes a few weeks to get use to, but so worth it.
My bills are low now.
Great with solar panels even cheaper, which is a massive bonus.

Get system and good app.
Easy to use
Great app for controlling HeatPump at home or importantly when away. Would like to see some sub pages with more data and trends like system pressure, freezing protection active etc for those of us geeks 😉
Constant network error
Never seems to connect always saying network error on WiFi and mobile data

No innovation for gas boiler control
App has stagnated for gas boiler users. Too much focus on its integration for heat pump users.
A disappointed gas boiler user.

So far so good
We have had shop, solar and batteries for 9 months. The house is just as comfortable as it was with oil heating. So far apart from 3 months over winter we break even or are in credit. After 12 months we will have a much better idea of costs.
Ability to save Weekly Planner
Fabulous app, and whole system. To make it even better I would like to be able to save my Weekly Planner settings (preferably multiple versions) so that I can seamlessly switch between profiles I create.
