I see zero values on export energy registers. Is the template configured incorrectly?

If you are using an import-only model (article 33420518 or 33420505), export registers are not populated by the meter. This is expected behavior. Only Import+Export models (43420518, 43420505) return export data.

What is the default Modbus address and baud rate for the NZR EcoCount SL?

The default device address is 1 and the default baud rate is 19200. Verify these settings on the meter display or configuration interface before connecting.

Energy values seem duplicated in the register list. Which ones should I use?

The meter provides energy totals in both kWh and Wh as uint32 register pairs. Use whichever unit fits your reporting needs. The kWh registers are convenient for dashboard display, while Wh registers offer higher resolution.

Can I reset the energy counter remotely?

Yes. The template includes a write command to reset the T0 counter. Use this function from the ModbusCloud portal during commissioning or when you need to clear accumulated energy data.
