Unusable for more than a month now. Purchased the gateway in a hope that the system can be controlled remotely but it does not work. On the main page it always displays a message that "No data available yet. It might take a few minutes to collect all data from your appliance." But it never comes. Cannot check water temperatures, cannot set room temperature or timing. Completely not fit for purpose. It was not perfect before but for a few weeks it is complete rubbish.

App is totally unusable. Installed it, registered an account, then tried to create a home - but when I entered the serial number for my boiler, I got a network error message. Tried for the next two days, same thing. Cleared local storage, deleted app, reinstalled app - exactly the same thing. I can't add my boiler to manage it in the app, which is the point of the app! Very disappointed and not a great first impression of Vaillant

Potentially a good app, but definitely needs some work. The most annoying bug is the status page, which frequently fails to update certain data so that the information it shows is inconsistent. For example, it will show an operation mode of heating, but a power consumption by the heat pump of 8W (what it consumes when it's in standby). The home screen is odd too - it shows an orange bar for the heating when it is on, but the hot water stays green when it is heating.
