The gateway cannot connect to the SDM630-TCP. What should I check?

Verify that the meter and the gateway are on the same subnet. By default, DHCP is disabled on the meter, so you must manually set an IP address via the front-panel menu before the meter will respond on the network.

Do I need to change the baud rate setting on the meter?

Yes. The internal Modbus communication speed may need to be set to 57600 baud. Navigate to the Set CoState menu on the meter and set the value to 0 / 5760. This setting is not always documented in the printed manual.

Why do power readings appear in kilowatts instead of watts?

The template applies a scaling factor that converts watt values to kilowatts. A raw register value of 1000 W will display as 1 kW on the dashboard.

Can I use this template for the RS485 version of the SDM630?

No. This template is designed for the SDM630-TCP variant, which uses Modbus TCP over Ethernet. The RS485 version (SDM630-Modbus) requires a different protocol configuration and a serial Modbus RTU connection.
