# WaterSmart

> WaterSmart is a Marketplace integration for Home Assistant. It has 50 installs sharing analytics, needs the vendor's cloud and was last updated September 8, 2026.

WaterSmart is an integration that reads water usage data from utilities that use WaterSmart by VertexOne. It adds sensors for the most recent full day of usage and the most recent hour of usage, both in gallons, with related hourly entries as attributes. It imports the hourly series into long-term statistics so the water consumption section of the Energy dashboard can use it. Later refreshes re-import roughly the last two days, because the utility keeps revising recent hours. An action fetches hourly water usage history on request. It relies on the vendor's cloud, scrapes the web interface, and is set up in the UI with the utility subdomain, username and password.

## From the README

>
> Note: data will not be updated frequenly because the water utilities do not always update this data continuously.
