# Liquid-Check

> Liquid-Check is a Marketplace integration for Home Assistant. It has 72 installs sharing analytics, works locally and was last updated June 17, 2026.

Liquid-Check is an integration for the Liquid-Check water level meter for cisterns, made by SI-Elektronik. It talks to the device locally and is set up in the UI by entering the device host or IP address and a polling interval, both of which can be changed later in the options. It adds sensors for level, contents, water level, last measurement, error, firmware, hardware, tank max level, system uptime, pump starts, pump total runtime and Wi-Fi signal. Some of these values are marked as diagnostic entities. A button and an action both start a new measurement, either for all configured devices or for a single one, and values refresh automatically after about ten seconds. Entity names are translation-ready, with German and English included.
