The WaterFlowKit v2 provides you with real-time insight into water consumption and water temperature per measuring point. You can connect a maximum of 4 water flow sensors per kit.
You order the sensors separately, so you can choose the right size and type for your piping. Each sensor comes with a 1-meter connection cable and cannot be connected to the WaterFlowKit without this cable.
Available sizes: G1/2" (DN15), G3/4" (DN20), G1" (DN25), G1 1/2" (DN40), and G2" (DN50). View all sizes and applications.
Available in: Brass and Stainless Steel.
Brass: robust and economical, suitable for most household applications.
Stainless Steel: food-safe, hygienic, and recommended for drinking water or when extra durability is desired.
Optional: USB-C Adapter Set with 3-meter cable. You can also use PoE for power.
More information, applications, and technical details can be found on the extensive product page and in the manual.

Quick start guide
Find answers to the most frequently asked questions about the WaterFlowKit.
The WaterFlowKit is designed for easy installation. You can attach it to the water line of your choice, such as the kitchen or bathroom faucet. Attach the provided flow sensors to the pipeline and connect the kit to your Home Assistant system.
Yes, you have the flexibility to connect up to two flow sensors to the WaterFlowKit. This allows you to track water consumption at different locations in your home.
Besides the WaterFlowKit, you need a functioning Home Assistant system as well as a WiFi connection.
The WaterFlowKit not only measures water consumption in liters per minute but can also measure the waters temperature as it flows through the sensors. It also measures the temperature and humidity of the room where the kit is located.
Yes, with the WaterFlowKit you can set up notifications in Home Assistant based on custom water consumption thresholds, allowing you, for example, to receive alerts when unusually large amounts of water are consumed.
Yes, you can view and analyze historical data of your water consumption over days, weeks, months, and years in Home Assistant, providing insight into your water consumption patterns.
Yes, the WaterFlowKit is suitable for both cold and hot water lines and can measure the water temperature as it flows through the sensors.
The WaterFlowKit is designed for indoor use and is not recommended for outdoor use where it could be exposed to extreme weather conditions.
