Discharge

Use this action to start discharging one or more Indevolt batteries with a set maximum power until the target state of charge is reached. Each device switches to real-time control mode if needed.

Using this action from the user interface

If you prefer building automations and scripts visually, Home Assistant walks you through this action step by step. You pick what to target, tweak a few options, and save. No YAML knowledge required.

To start discharging from an automation or a script:

  1. Go to Settings > Automations & scenes.
  2. Open an existing automation or script, or select Create automation > Create new automation.
  3. If you’re setting up a new automation, add a trigger in the When section. Scripts don’t need a trigger. They run when something else calls them.
  4. In the Then do section, select Add action.
  5. Search for and select Indevolt: Discharge.
  6. Select the Indevolt devices in the Device(s) field, then set the Target SOC and Max. power.
  7. Select Save.

This action does not support targets. In the UI, you select the Indevolt devices through the Device(s) field instead of choosing an area, device, entity, or label.

Options in the UI

Device(s) (Required)

The Indevolt devices to start discharging.

Target SOC (Required)

The target state of charge, as a percentage. Discharging stops when it is reached.

Max. power (Required)

The maximum discharging power, in watts.

Using this action in YAML

If you work directly in YAML, or you want to know exactly what Home Assistant does under the hood, this section has the technical reference. It lists the field names you use in YAML, their types, and which ones are required.

In YAML, refer to this action as indevolt.discharge. A basic example looks like this:

ActionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called *sequence*. [Learn more]
action: indevolt.discharge
data:
  device_id: a1b2c3d4e5f6
  target_soc: 10
  power: 800

This discharges the battery at up to 800 watts until it reaches 10%.

Options in YAML

device_id string | list Required

The Indevolt devices to start discharging.

target_soc integer Required

The target state of charge, as a percentage from 0 to 100. Discharging stops when it is reached.

power integer Required

The maximum discharging power, in watts, from 0 to 2400.

Tip

You don’t need to edit YAML to use these examples. Copy a YAML snippet from this page, open the automation editor in Home Assistant, and press Ctrl+V (or Cmd+V on Mac). Home Assistant automatically converts the pasted YAML into the visual editor format, whether it’s a full automation, a single trigger, a condition, or an action.

Automation: discharge the battery during evening peak to avoid grid draw

When the evening peak tariff window starts and the battery has enough charge, discharge the battery to cover home consumption and avoid drawing expensive and carbon-intensive peak-time grid electricity.

  • Trigger: Time: 17:00
  • Condition: Battery SOC above 30 %
  • Action: Indevolt: Discharge (at 800 watts to 20 % SOC)
