eQ-3 MAX!
maxcube
The eQ-3 MAX! integration for Home Assistant allows you to connect eQ-3 MAX! components via the eQ-3 MAX! Cube. The components connects to the eQ-3 MAX! Cube via TCP and automatically makes all supported integrations available in Home Assistant. The name for each device is created by concatenating the MAX! room and device names.
