Control your GROHE Blue Pure, GROHE Red, GROHE Blue Home or Blue Professional Watersystem via your smartphone. The GROHE Watersystems App will not only help you during the configuration of your water system appliance, but will let you know when the filter or CO2 bottle will need replacing. You can easily reorder and track your past orders. Within this app, you can also set up favorites for pouring water in a predefined amount and sparkling grade. Notes: 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 the Watersystems App automatically. The web shop is not available in every country.
