Defines the current flow polarity.
If the value shown on the Overview page is inverted (e.g. charging shown as discharging), flip the direction here.

↔️ Tip: You can test direction by lightly charging or discharging the battery and observing the sign.

Some sensor types offer additional subtypes (e.g. variants, firmware versions, scaling differences).
This option appears automatically if required.

⚠️ Important: Selecting the wrong sensor type or subtype may lead to incorrect readings or system errors.

Make sure that the configured baud rate matches the one required by your current sensor.

You can find instructions on how to set the baud rate here.

⚠️ Important: An incorrectly configured baud rate will trigger a current sensor error and prevent communication.
