# My EcoWatt by RTE

> My EcoWatt by RTE is a Marketplace integration for Home Assistant. It has 358 installs sharing analytics, needs the vendor's cloud and was last updated October 22, 2026.

My EcoWatt by RTE is an integration that exposes the Ecowatt electricity grid levels from the French company RTE. It adds sensors and calendars to Home Assistant and relies on RTE's cloud API, so it needs an API client ID and secret from an RTE account. Hourly sensors show the Ecowatt level a set number of hours ahead, and daily sensors show it a set number of days ahead. A daily value reflects the worst hour of that day. Sensors for the current hour and the current day are created by default, along with one that shows when the next degraded period starts. It is set up in the UI and installed through the Marketplace.
