Why do some energy counters show zero even though instantaneous power readings are correct?

Energy registers use uint64 data types at non-contiguous addresses. Confirm that your gateway firmware supports 64-bit register reads and that the correct register addresses (e.g., 3717 for apparent energy import) are mapped. A firmware update on the gateway may be needed.

What baud rate or TCP port should I use?

Since the iEM2000 series communicates via Modbus TCP, baud rate settings do not apply. The default TCP port is typically 502. Verify the port setting in the meter network configuration menu.

The power and voltage values look garbled or extremely large. What is wrong?

Power and voltage registers use float32 encoding with a specific byte order. Make sure the gateway is configured for the correct byte order (typically Big Endian). Swapping the word or byte order in the gateway settings usually resolves this.

Can I connect multiple iEM2000 meters to one ModbusCloud gateway?

Yes. Assign each meter a unique Modbus unit ID and IP address. Then create a separate device instance in ModbusCloud for each meter, using the same template but with the individual connection details.
