What is wasserleser?
The wasserleser makes your water meter smart – without requiring any modifications to the meter itself.
How it Works
The wasserleser uses optical detection of the rotating metal disc above the red wheel in your water meter. This allows your water consumption to be captured precisely and reliably in digital form.
Key Features
- Compatibility: Works with water meters that have a metal disc above the red wheel
- Easy Installation: Simple mounting with adapter or adhesive metal plate
- Secure Attachment: Direct mounting on the meter with included accessories
- Smart Home Integration: Compatible with common smart home systems
- Real-time Data: Instant consumption information in the app
- Leak Detection: Automatic alerts for continuous water flow
- Timer Function: Set warnings for time or volume thresholds
