===== Current Sensor Settings =====

To configure the current measurement, go to **Current Sensor** in the sidebar.
==== Sensor Type ====

Select the type of current sensor used in your system.

''🔓 **Note:** Each sensor type requires a separate **unlock via grnbms.de** before it can be used.\\
Only unlocked types will be available in the dropdown.''

==== CAN Bus ====

If a **CAN-based sensor** is selected, choose the CAN bus the sensor is connected to.\\
Ensure the correct **baud rate** and **termination** are set under **Connections → CAN Bus**.
==== Direction ====

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.''
==== Sensor Subtype ====

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.''

==== Baud Rate ====

**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 [[:mk3:serialports|here]].

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