How can I enable neutral current readings on the Shelly Pro 3EM?

To enable neutral current readings on the Shelly Pro 3EM, you need to connect an additional CT clamp specifically for the neutral channel, which should have a 2-Pin MX3.0-2x1Y connector.

Once the neutral clamp is connected, follow these steps to enable and calibrate it:

1. Navigate to Settings.
2. Select Phase Calibration.
3. Select From phase: A, B, or C.
4. Select Calibrate Phase and choose Phase N.
5. Click on Calibrate.

After successful installation and calibration, the neutral readings will be available exclusively through the device's local web interface, sourced from the local EM.GetStatus API method.
