Water Meter Gateway

Monitor water consumption

Monitor real-time water consumption

The Water Meter Gateway makes your analog water meter smart. It gives you live insight into water consumption. This way, you can see exactly how much water you’re using when you shower, fill a bath, wash your hands, or water your garden.

3D view

Beautiful dashboards

Water consumption is displayed in clear overviews, providing you with more insight into water usage and how you might save money. You can use it with the Home Assistant energy dashboard, Homey, and Domoticz. You also get exclusive access to the Smart Gateways Water Meter Dashboard for Home Assistant, where you can see even more data.

Easy to install

The Water Meter Gateway is compatible with most analog water meters. The Water Meter Gateway is compatible with water meters from brands like Itron, Actaris, Elster, Sensus, Diehl Metering, Zenner, Schlumberger, Maddalena MVM, Honeywell, DH Metering Kent, and Hidroconta.
