Control your GROHE Blue Home or Blue Professional Water System 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. You can easily reorder and track your past orders. 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. 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 this new Watersystems App automatically. The Web shop is not available in every country.
