# 8.2 Device settings
Opening a device reveals tabs for configuration:
* **Settings** – edit basic properties: name, description, location, measurement type (e.g., standard.
* **Communication** – configure the protocol (e.g., Modbus TCP/IP), IP address, port and slave ID for the device to communicate with the platform.
* **Data** – view a table of real‑time parameters and their current values (e.g., power, consumption, voltage, 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 allows you to assign priority and choose which sub‑devices can be shed.
* **Manual Override** – create manual overrides for controllable modules. Specify the module, override value (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:
Manual: Battery Manual Charging/Discharging
This manual describes how to manually charge or discharge the battery using a manual override in the EMS system.
WARNING: During a manual override, the algorithm will no longer control the battery automatically. The system will only follow the configured setpoint.
### Step 1: Navigate to My Devices
1\. Log in to the EMS portal.
2\. Click “My Devices” in the left navigation menu.
### Step 2: Open the Device Settings
3\. You will see an overview of all devices (Device Overview).
4\. Find the desired device in the list.
5\. Click the gear icon (⚙) to the right of the device to open the device settings.
### Step 3: Navigate to Manual Override
6\. You are now on the “Device Settings” page.
7\. Click the “Manual Override” tab at the top of the page.
### Step 4: Configure the Override
Fill in the following fields:
• Controllable module: Select the module you want to control (e.g. charge/discharge power).
• Override value (kW): Enter the desired power level. Use a:
• • Negative value (e.g. −20 kW) to discharge the battery.
• • Positive value (e.g. +20 kW) to charge the battery.
• Period: Select the desired time period for which the override should be active.
8\. Click the “Create Override” button to save and activate the setting.
### Step 5: Monitor and Stop the Override
9\. Under “Current Overrides” you can see the active override with its date, module, type, value, and period.
10\. To end the override early, click the “Stop” button next to the relevant override.
11\. Previous overrides can be found in the “Previous Overrides” section at the bottom of the page.
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, in order to avoid grid overload or violations of your network operator's requirements.
Note: Once the configured period has elapsed, the algorithm will automatically resume control of the battery.
