Make your non-digital water meter digital! Running ESPHome, easy install for Home-assist.

The Muino Smart Water Meter is an innovative solution for measuring water consumption and transmitting data wirelessly to applications like Home-Assistant. Unlike traditional water meters with spinning wheels, our device utilizes special sensors to translate usage into 100sub-millilitres accurately. This approach overcomes common issues faced by proximity sensor-based techniques, such as double or missed detections. Additionally, our device offers easy installation with simple screws and a power cable, eliminating the need for complex construction. Moreover, it provides a higher resolution than a litre, addressing concerns about leakage or lower measurement precision.

The Muino Smart Water Meter is a single-board device that measures water consumption with sub-100 millilitre accuracy. The other big benefit is the ease of installation, for friends/family that wanted a similar solution this is easier to use.
