# Emoncms

> Emoncms is a built-in integration for Home Assistant. It has 401 installs sharing analytics and works locally.

Emoncms is a built-in Home Assistant integration that reads energy monitoring feeds from an Emoncms server. It adds sensors for the selected feeds and works locally. Setup happens in the UI with the server URL, which starts with http or https, and an API key. A synchronization mode lets feeds be picked manually, which is the default, or synchronized all at once. The chosen feeds can be changed later in the options, and connection settings can be edited without removing the integration. A repair notice appears in Settings, Repairs when the Emoncms version needs an upgrade.
