Indevolt

The Indevolt integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] enables direct local communication between Home Assistant and your Indevolt energy storage devices.

Use cases

With this integration, you can monitor energy production, consumption, and battery status in real time. You can also manage battery working modes, control real-time charging and discharging behavior, and configure power limits and other battery protection settings.

Beyond basic monitoring, the Indevolt integration enables advanced energy management automations within Home Assistant. For example, you can:

• Optimize battery charging and discharging based on solar production forecasts
• Automatically adjust energy modes to take advantage of variable electricity pricing
• Prevent grid feed-in during peak tariff periods by dynamically limiting output power
• Maintain a minimum battery charge for backup scenarios by adjusting discharge limits when applicable
• Coordinate battery behavior with other Home Assistant energy devices for whole-home optimization

Supported devices

The integration supports the following devices:

• BK1600 / BK1600 Ultra
• SolidFlex 1200 / SolidFlex 2000 / PowerFlex 2000

Prerequisites

1. Connect your Indevolt device and Home Assistant to the same local network.
2. Ensure the Indevolt device is powered on and has acquired a network IP address.
3. In the Indevolt app, enable the Local API and set the protocol to http.

Configuration

To add the Indevolt device to your Home Assistant instance, use this My button:

Indevolt can be auto-discovered by Home Assistant. If an instance was found, it will be shown as Discovered. You can then set it up right away.

Supported functionality

The Indevolt integration provides sensors for monitoring your device (read only).

Buttons

The following button entity allows triggering device actions directly from Home Assistant.

• Enable standby mode: Puts the battery in standby mode which pauses battery charging and discharging. Change the energy mode to resume normal battery activity.

• LED indicator: Enable or disable the LED indicator (switch)

Actions

Action: Charge the battery (real-time control mode)

The indevolt.change_energy_mode action configures the battery to start charging with specified maximum power to the target SOC. The device will automatically switch to real-time control mode if needed.

• Data attribute: device_id
  • Description: The device_id of the Indevolt device(s)
  • Optional: No
• Data attribute: power
  • Description: The maximum charging power (0 - 2400W)
  • Optional: No
• Data attribute: target_soc
  • Description: The target SOC (%): charging will stop when reached
  • Optional: No

Example

action: indevolt.charge
data:
  device_id: YOUR_DEVICE_ID
  power: 1000
  target_soc: 100

Action: Discharge the battery (real-time control mode)

The indevolt.change_energy_mode action configure the battery to start discharging with specified maximum power to the target SOC. The device will automatically switch to real-time control mode if needed.

• Data attribute: device_id
  • Description: The device_id of the Indevolt device(s)
  • Optional: No
• Data attribute: power

Data updates

The Indevolt integration automatically retrieves data from your devices by polling the OpenData API every 30 seconds. If an update fails, the integration will retry again at the set interval (self-recovery).

Known limitations

• Real-time configuration changes may appear with a small delay in Home Assistant and the Indevolt app.
• Energy mode can only be set when the device is not in “Outdoor / Portable”-mode (BK1600 / BK1600 Ultra).
• Some sensors are device generation-specific and may not appear for all models.
• Some sensors / configurations available in the app are not (yet) available in the integration.
• The inverter temperature only shows when the inverter is active (BK1600 / BK1600 Ultra).
• The SolidFlex 1200 identifies itself as a SolidFlex 2000 device.

Troubleshooting

Cannot add device or obtain data

1. Ensure the device is powered on and functioning normally.
2. Confirm both the device and Home Assistant are connected to the same local network.
3. Ensure the device’s IP address is correct and hasn’t changed.
4. Check the device’s settings in the Indevolt app to ensure that the API is enabled in “HTTP” mode.

Check the Home Assistant logs for more information.
