Change setting

Use this action to change a setting on a Home Connect appliance, for example to turn on the child lock or switch the appliance into a different mode. You pick the appliance, the setting you want to change, and the value to set.

Settings are identified by their Home Connect key, such as BSH.Common.Setting.ChildLock. The value can be text, an integer, or a toggle, depending on what the setting expects.

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 change a setting 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. From the list of actions, search for and select Change setting.
6. Select the appliance you want to change.
7. Enter the key of the setting and the value to set.
8. Select Save.

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 home_connect.change_setting. A basic example that turns on the child lock looks like this:

action: home_connect.change_setting
data:
  device_id: a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6
  key: "BSH.Common.Setting.ChildLock"
  value: true

Options in YAML

Good to know

• Which settings you can change depends on your appliance. The Home Connect API does not always match the Home Connect app, so some settings available in the app may not work through Home Assistant.
• The value must match the type the setting expects. A toggle uses true or false, while other settings expect text or an integer.
