The sensor puck itself tracks all liquids the same, but you can change the drink types in the HidrateSpark app.
There are 6 drink types in the app: Water, Tea, Coffee, Wave Energy, Wave Immune Support, and Wave Electrolytes. And you can choose the drink type your Tumbler/bottle is recording by tapping on the drink icon on the bottle card. For example, if you select coffee, your drink log will show all records from this Tumbler as coffee. You can easily switch the drink types for a Tumbler/bottle if you fill it with a different drink type.
