Smart sensors for Home Assistant

Make your water meter smart

The Muino reader sits on your existing water meter and measures every drop with sub-100 ml precision. It runs ESPHome and shows up straight in Home Assistant, so you can track usage and spot leaks.

How it works

Up and running in three steps

1

Mount it

Fix the reader on your water meter with a few simple screws. No plumbing, no construction.

2

Power it

Plug in the power cable and connect it to your Wi-Fi. It runs ESPHome out of the box.

3

See your usage

Your water use shows up in Home Assistant and its energy dashboard, down to sub-100 ml.

Sub-100 ml precision

Higher resolution than a litre, so even a small drip becomes visible.

No missed counts

Reads the rotating disk directly, avoiding the double or missed detections of proximity sensors.

Leak detection

Continuous flow you didn’t expect? Set an alert in Home Assistant and catch leaks early.

Made by a maker

Muino started from a love for electronics and a simple wish: a water meter in the Home Assistant energy dashboard, to understand and save water.
