Set date & time

Use this action to set the date and time on your Bosch alarm panel. When you do not provide a date and time, the current date and time of your Home Assistant instance are used.

This is handy to keep the clock on your panel in sync, for example with an automation that updates it after a power outage or on a regular schedule.

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 set the panel date and time 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 search box, search for and select Bosch Alarm: Set date & time.
  6. Select the Config entry of the panel to update. Optionally, set the Date & time you want.
  7. Select Save.

This action does not support targets. In the UI, you are not prompted to choose an area, device, entity, or label.

Options in the UI

Config entry (Required)

The Bosch alarm panel to update.

Date & time (Optional)

The date and time to set. When not provided, the current date and time are used.

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 bosch_alarm.set_date_time. 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: bosch_alarm.set_date_time
data:
  config_entry_id: a1b2c3d4e5f6a1b2c3d4e5f6a1b2c3d4
  datetime: "2025-05-01T12:00:00"

This sets the date and time on the selected panel to the given value.

Options in YAML

config_entry_id string Required

The Bosch alarm panel to update.

datetime string

The date and time to set. The time zone of your Home Assistant instance is assumed. When not provided, the current date and time are used.

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: keep the panel clock in sync

Bosch alarm panels can drift over time. This automation re-syncs the panel clock to your Home Assistant time every night, so the panel always shows the correct date and time. Because no date and time are provided, the current Home Assistant time is used.
