OVUM MIRA

← Heating

The Modbus TCP server must be enabled at the display under "Settings / Network" and the Modbus login code must be disabled (value 1) since evcc does not perform the login sequence. The PV status source must be set to "EMS" and the PV data source to the power setpoint at the display. Requires MIRA controller software V1.1.3 or later.

Supported features

  • Built-in meter: Support for an integrated meter.
  • Dimmable: Power consumption can be reduced (e.g. §14a EnWG). See External Control.
