Why am I reading zero values for all registers?

Check that the Smartlink gateway is online and reachable on the network. Verify the IP address and TCP port (usually 502) configured in the ModbusCloud template match the Smartlink settings. Also confirm the correct Modbus unit ID for the specific PowerTag.

What encoding do the registers use?

All analog registers (voltage, current, power) use float32 encoding. The total imported energy register at address 3203 uses uint64 encoding and reports values in kWh.

Can I use this template with a single-phase PowerTag?

This template is designed for three-phase PowerTag models. A single-phase sensor will only populate one phase of data. Use a dedicated single-phase template if available for cleaner results.

Which Schneider PowerTag models are supported?

The template supports the PowerTag flex series, PowerTag NSX, PowerTag F160, and PowerTag Rope. All models expose the same register map through the Smartlink gateway.
