# Device settings

Opening a device reveals several configuration tabs:

* **Settings**: edit basic properties such as name, description, location, and measurement type.
* **Communication**: configure the protocol, for example Modbus TCP/IP, plus the IP address, port, and slave ID used by the device to communicate with the platform.
* **Data**: view a table of real-time parameters and their current values, such as power, consumption, voltage, and currents. Each row shows the parameter name, current value, and timestamp.
* **Load Management**: enable automatic load management for the device. Define a maximum power and hysteresis. The platform will switch off lower-priority devices when the total power exceeds this limit. A table lets you assign priority and choose which sub-devices can be shed.
* **Manual Override**: create manual overrides for controllable modules. Specify the module, override value in kW, and time period. Current and previous overrides are listed below.

These features allow fine-grained control over each meter, PV string, battery, or inverter.

### Manual override

This manual describes how to manually charge or discharge the battery using a manual override in the EMS system.

{% hint style="warning" %}
During a manual override, the algorithm no longer controls the battery automatically. The system only follows the configured setpoint.
{% endhint %}

{% stepper %}
{% step %}

### Navigate to **My Devices**

1. Log in to the EMS portal.
2. Click **My Devices** in the left navigation menu.
   {% endstep %}

{% step %}

### Open the device settings

1. You will see an overview of all devices.
2. Find the desired device in the list.
3. Click the gear icon to the right of the device to open the device settings.
   {% endstep %}

{% step %}

### Open **Manual Override**

1. You are now on the **Device Settings** page.
2. Click the **Manual Override** tab at the top of the page.
   {% endstep %}

{% step %}

### Configure the override

Fill in the following fields:

* **Controllable module**: select the module you want to control, for example charge or discharge power.
* **Override value (kW)**: enter the desired power level:
  * Use a negative value, for example `-20 kW`, to discharge the battery.
  * Use a positive value, for example `+20 kW`, to charge the battery.
* **Period**: select the period for which the override should be active.

Click **Create Override** to save and activate the setting.
{% endstep %}

{% step %}

### Monitor and stop the override

1. Under **Current Overrides**, you can see the active override with its date, module, type, value, and period.
2. To end the override early, click **Stop** next to the relevant override.
3. Previous overrides appear in the **Previous Overrides** section at the bottom of the page.
   {% endstep %}
   {% endstepper %}

{% hint style="warning" %}
When setting the override value, always take into account the applicable import and export limits of your connection. Never set a value that exceeds the permitted import or export limit, to avoid grid overload or violations of your network operator's requirements.
{% endhint %}

{% hint style="info" %}
Once the configured period has elapsed, the algorithm automatically resumes control of the battery.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.voltmasters.io/voltmasters-platform/8.-device-management/8.2-device-settings.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
