Why do per-phase power values seem 1000 times smaller than the total active power?

Per-phase active power registers return values in kilowatts, while the total active power register returns values in watts. Make sure the scaling factor in your dashboard accounts for this difference.

Some energy registers return zero or do not respond. What should I check?

Not all Schneider meter models support every register in this template. Consult the Modbus register map for your specific model (e.g. iEM2000 vs PM8000) and disable unsupported registers in the template.

How should I handle the uint64 energy registers?

Active and reactive energy totals use uint64 format, which spans four consecutive Modbus words. Ensure the ModbusCloud gateway is configured to read all four words and that the byte order matches the Schneider default (big-endian).

The meter does not respond to Modbus TCP requests. What could be wrong?

Verify that the Modbus TCP service is enabled on the meter, the IP address is correct, and no firewall is blocking port 502. Also confirm that the unit ID in the template matches the one configured on the meter.
