wasserleser – your smart water meter for complete transparency

Water flows – but where exactly?

How much water do you really use? And what happens when a tap is dripping unnoticed or a pipe is leaking?

A single, continuously dripping faucet can waste up to 15 liters per day – that's an incredible 5,500 liters per year.
With the water reader, you can make your existing water meter smart and keep an eye on your water consumption in real time.

Problem

Water is one of the most valuable resources of our time – but we often only realize too late when we are wasting too much of it. Conventional water meters are analog and passive. They provide no warning, no live data , and certainly no transparency .
Whether a tap is dripping, a toilet is constantly running, or a pipe is leaking: many losses go unnoticed – and accumulate over weeks to hundreds of liters and high costs . For households, this means: no control, no overview, no early detection.

Solution: wasserleser

The wasserleser transforms your existing meter into a smart, digital device – without any modifications.

As an intelligent reading head, it detects every rotation of your water meter and transmits the data to the app in real time. You can see exactly when and how much water is being used – whether in the morning while showering, at noon while cooking, or at night when everything should actually be standing still.

Instead of just knowing the meter reading, you get a feel for your daily life : You recognize consumption peaks, identify continuous runs and are immediately notified of unusually long or constant consumption . This allows you to intervene early – before undetected losses become expensive.

The wasserleser gives you what conventional meters don't offer: transparency, control, and awareness of your water consumption – intuitive, understandable, and accessible everywhere.
