[Yuso](https://www.yuso.com) is an external energy supplier and aggregator that operates the connected assets by sending steering signals to the EMS. The integration uses a **certificate-secured MQTT** connection over **AWS IoT**: the controller connects to Yuso's AWS IoT endpoint and exchanges setpoints over the connection.

**Supported steering:** batteries, PV, imbalance market.

### Connection method

-   **Protocol:** MQTT (TLS, client-certificate authentication) via AWS IoT
-   **Endpoint:** Yuso's AWS IoT MQTT endpoint (`*.iot.us-east-1.amazonaws.com`)
