# Marstek Local API

> Marstek Local API is a Marketplace integration for Home Assistant. It has 973 installs sharing analytics, works locally and was last updated November 7, 2025.

Marstek Local API is an integration that connects Marstek energy storage systems to Home Assistant over the local network. It exposes the devices as sensors, binary sensors and buttons, without relying on a cloud connection. Devices on the network can be found automatically and offered for adding, or an IP address and port can be entered by hand. The options let the polling interval be set in seconds, and let devices be renamed, added or removed later. A diagnostics download is included for attaching to bug reports. It is added as a custom repository in the Marketplace and set up in the interface.
