Yuso
Connecting Yuso over MQTT through AWS IoT: a Thing name and Client ID per connection, and the certificate files Yuso supplies.

Yuso 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.
