Implement a new Device to Backend

9

Okay, i got it running now :slight_smile:

Next question:

  • The Production is shown as “Consumption” but in fact there is no “Consumption-Meter” there, so it should be sent to grid instead on the UI…

This is my Impl. so far, where i handle if the inverter is only a String-Inverter without a Battery:

@Override
protected ModbusProtocol defineModbusProtocol() throws OpenemsException {
    if (isFeedGrid()) {
        // In feed-grid mode, read only production and grid feeding registers
        return new ModbusProtocol(this, new FC4ReadInputRegistersTask(4989, Priority.HIGH,
                // Read production registers
                m(ElectricityMeter.ChannelId.ACTIVE_PRODUCTION_ENERGY,
                        new UnsignedDoublewordElement(5003).wordOrder(WordOrder.LSWMSW),
                        ElementToChannelConverter.SCALE_FACTOR_3),
                new DummyRegisterElement(5004, 5029),
                // Read grid feeding registers
                m(ElectricityMeter.ChannelId.ACTIVE_POWER,
                        new UnsignedDoublewordElement(5030).wordOrder(WordOrder.LSWMSW))
        ));
    } else {

How do i fix this?
