About this app

Control your GROHE Blue Chilled and Sparkling 2.0 faucet via your smartphone. The GROHE Watersystems App will not only help you during the configuration of your watersystem appliance, but will let you know when the filter or CO2 bottle will need replacing.

Within this app, you can also set up favourites for pouring water in a predefined amount and sparkling grade, and you can monitor your water consumption.

Note: This App replaces the GROHE Ondus App. If you have used the GROHE Ondus App before, then your connected GROHE Blue watersystem will be transferred into this new Watersystems App automatically.

Excrement masquerading as an app. The app needs you to log in constantly, it won't stay connected to the device for more than a few months after which you need to go through the painful setup process again. Then it will connect and work for another few months, if your are lucky. Water consumption is for water dispensed via the app only.. Seriously?!? Please explain how that is in any way useful. I will never buy another grohe product again. I have others in my house and they are similarly flawed

Login now works, but Google login linking still broken. Also after the latest fw update the auto fluah is completely broken. Now the setting does stay on, but the device never does the flushing even the notification is in the app.

App very confusing and poorly made. Hard to get going and then when it does it fails to show the same CO2 reading as the device. Every action you take just says "an error occurred. Please try again later!". I have checked the device is connected to my network, and reinstalled the app. Very frustrating.
