Water is the forgotten meter at home: you only see what went through on the annual bill. With the WaterMeterKit V3 you follow your usage minute by minute in Home Assistant, catch hidden consumption and leaks, and saving finally becomes concrete, fully local, no subscription.
The WaterMeterKit V3 offers a simple way to monitor your water consumption in real time in Home Assistant.
The kit is designed for households that want more insight into their water consumption and want to save water more smartly. Thanks to its broad compatibility with many European water meters, installation is quick and easy in most situations.
Power via USB-C:
The WaterMeterKit V3 is powered via USB-C. For the best and most stable operation, we recommend our USB-C Adapter Set with 3-meter cable. This is perfectly suited for this product and can be easily ordered as an option.
Also works over Thread:
Thanks to the updated hardware, the WaterMeterKit V3 also works over Thread with the Thread firmware: without WiFi, locally with Home Assistant through your Thread border router. By default it runs on WiFi.
Tip: measure water and energy or prefer Ethernet/PoE?
Do you want to read your energy consumption via the P1 port in addition to water consumption, or do you want to use a wired Ethernet connection with PoE? Then choose the WaterP1MeterKit V4. It combines water and energy measurement with WiFi, Ethernet, and PoE.

Ik bestelde de WaterMeterKit V2.0 voor mijn analoge Sensus watermeter. De bestelling werd adequaat afgehandeld. Na ontvangst bleek installatie met de bijgeleverde adapter en handleiding werkelijk zeer eenvoudig. Gewoon netjes het stappenplan volgen. Geweldig om te zien dat Home Assistant de WaterMeterKit meteen herkent. Prima product! Aanrader.
GoogleDe UltimateSensor Mini, WatermeterKit en de P1MeterKit heb ik nu een aantal maanden in gebruik. Voor al deze producten geldt dat het in gebruik nemen en toevoegen aan HomeAssistant zeer eenvoudig was. Zeer tevreden over de producten en de service.
GoogleIn most cases, yes. The WaterMeterKit is designed to fit most common analog water meters from well-known brands. We recommend always checking our list of compatible water meters, currently, we support: Actaris, DH Metering, Diehl (with a special clip-on holder), Elster, Hidroconta, Honeywell, Itron, Maddalena, Schlumberger, Sensus, and Zenner.
Installation is simple. Place the provided adapter on your water meter, connect the kit to wifi, and Home Assistant will automatically detect the device.
Absolutely. With the WaterMeterKit, you can track your water consumption by the hour, day, month, and year and compare it in clear charts.
Yes. The WaterMeterKit has a built-in Thread radio. With the Thread firmware it joins your existing Thread network and talks to Home Assistant locally through your Thread border router, without WiFi. Because it sends little data, the WaterMeterKit is a great fit for Thread. Our guide shows you step by step how to set it up.
No. Like Zigbee, Thread uses the 2.4 GHz band, but it is a different protocol. You don't pair the WaterMeterKit as a Zigbee device; it connects through your Thread border router.
Certainly! The WaterMeterKit provides real-time insight into your water consumption, allowing you to see how much water you use in daily activities directly.
The WaterMeterKit works with Home Assistant through ESPHome, locally and without a subscription. No Home Assistant? Use our SmartHomeShop app with cloud firmware, an account and internet. You can also use both at the same time.
No, the installation is designed to be simple. The included instructions will guide you step by step.
Yes. With the Thread firmware you don't need WiFi. Thread works locally with Home Assistant; if you want to use the SmartHomeShop app, choose the WiFi firmware. If you switch between WiFi and Thread firmware through the Device Builder, your meter total stays on the kit. The web flasher returns the kit to factory settings, so write your total down first.
A Thread border router, for example Home Assistant with a Connect ZBT-1 or SkyConnect, an existing Thread network and the ESPHome Device Builder. You install the Thread firmware on the kit over USB-C the first time.
