Hello Jonas! You can use many Eve Aqua with the app Eve (or Home from Apple). In Eve you can set an individual watering plan for each Eve Aqua you have. For any remote access a home hub is mandatory by Apple. When using the letest model of Eve Aqua we recommend using a HomePod mini or the upcoming new Apple TV 4K because it supports Thread. Best regards, Volker
