title: "Integrating your water usage"
|
|
description: "Learn how to add information about your water usage to Home Assistant home energy management."
|
|
---
|
|
|
|
Home Assistant allows you to track your water usage in the home energy management too.
|
|
|
|
Although water is not strictly "energy", it is still a valuable resource to track and monitor as it is often tightly coupled with energy usage (like gas). Additionally, it can help you reduce your ecological footprint by using less water.
|
|
|
|
## Hardware
|
|
|
|
Home Assistant will need to know the amount of water that is being consumed in order to be able to track it. Several hardware options are available to do this.
|
|
|
|
We have the following integrations available for existing products that can provide information about water usage:
|
|
|
|
- [Flo](/integrations/flo)
|
|
- [Flume](/integrations/flume)
|
|
- [HomeWizard Energy](/integrations/homewizard)
|
|
|
|
Alternatively, the following shops sell ESPHome-based devices, that use a proximity sensor to detect a rotating magnet in your water meter and use that pulse to count each liter of water used.
|
|
|
|
- [S0tool](https://huizebruin.github.io/s0tool/) ("Made for ESPHome" approved)
|
|
- [Waterlezer dongle](https://smart-stuff.nl/product/esphome-waterlezer-dongle/) (Dutch)
|
|
- [Slimme Watermeter Gateway](https://smartgateways.nl/product/slimme-watermeter-gateway/) (Dutch)
|
|
- [watermeterkit.nl](https://watermeterkit.nl/) (Dutch)
|
|
|
|
Maybe you like to build one yourself?
|
|
- Pieter Brinkman has quite a [nice blog article on how to create your own water sensor](https://www.pieterbrinkman.com/2022/02/02/build-a-cheap-water-usage-sensor-using-esphome-home-assistant-and-a-proximity-sensor/) using ESPHome, or [build a water meter](https://www.ztatz.nl/p1-monitor-watermeter/) that works with the [P1 Monitor](/integrations/p1_monitor) integration.
|
|
- [AI-on-the-edge-device](https://github.com/jomjol/AI-on-the-edge-device) is a project running on an ESP32-CAM and can be fully integrated into Home Assistant using the Home Assistant Discovery Functionality of MQTT. It digitalizes your gas/water/electricity meter display and provides its data in various ways.
|
|
- [watermeter](https://github.com/nohn/watermeter) running classic OCR and statistical pattern recognition on any system supporting Docker
|
|
|
|
If you manually integrate your sensors, for example, using the [MQTT](/integrations/mqtt) or [RESTful](/integrations/rest) integrations: Make sure you set and provide the `device_class`, `state_class`, and `unit_of_measurement` for those sensors.
|
|
|
|
For any of the above-listed options, make sure it actually works with the type of water meter you have before getting one.
