Battery stopped charging
The Battery stopped charging trigger fires when a battery-powered device transitions from actively charging to not charging. A device stops charging when it is unplugged, removed from its dock, or when it reaches full charge and the charger cuts off. Use this trigger to detect when a device is unplugged unexpectedly, confirm when a charge cycle completes, or start automations that should run once a device is ready to use.
Requires the Purpose-specific triggers and conditions Labs preview feature. Enable it at Settings > System > Labs.
Using this trigger from the user interface
If you prefer building automations visually, Home Assistant walks you through this trigger step by step. You pick what to watch, tweak a few options, and save. No YAML knowledge required.
To use Battery stopped charging in an automation:
- Go to Settings > Automations & scenes.
- Open an existing automation, or select Create automation > Create new automation.
- In the When section, select Add trigger.
- Select what you want to monitor. Under By target (see Targets), pick the area your device is in (like your bedroom or office). You can also select a device, a specific entity, or a label.
- From the triggers shown for that target, select Battery stopped charging.
- Under Trigger when (see Behavior), pick Each, First, or All to control how the trigger behaves when multiple devices are targeted.
- Under For at least, set how long the device must remain not charging before the trigger fires. Leave it at zero to fire immediately.
- Select Save.
Options in the UI
When multiple devices are targeted, controls when the trigger fires:
- Each (default): fires every time any targeted device stops charging.
- First: fires only on the first device that stops charging.
- All: fires only after every targeted device stops charging.
Using this trigger 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, Battery stopped charging is referred to as battery.stopped_charging. A basic example looks like this:
trigger: battery.stopped_charging
target:
entity_id: sensor.phone_battery
This fires every time sensor.phone_battery stops charging.
Options in YAML
YAML sometimes provides additional options for more complex use cases that are not available through the UI.
When multiple devices are targeted, controls when the trigger fires:
-
any(Each in the UI, default): fires every time any targeted device stops charging. -
first(First in the UI): fires only on the first device that stops charging. -
last(All in the UI): fires only after every targeted device stops charging.
Targets of the trigger
This trigger requires a target. The target is the object that Home Assistant will watch. You can select a single entityAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service. [Learn more], a device, an area, a floor, or a label as a target, and Home Assistant will watch every matching battery entity behind that target.
-
Entity: one specific battery entity, such as
battery.living_room. - Device: every battery entity that belongs to a device.
- Area: every battery entity in a room or area.
- Floor: every battery entity on a floor.
- Label: every battery entity that shares a label.
You can also select different target types in one trigger. For example, you can add a specific entity and an area as targets in the same trigger to monitor both of them at once.
Behavior with multiple targets
When you target more than one entity (or select an area, floor, or label that contains several), the Trigger when option controls how the trigger responds:
-
Each (
anyin YAML, default): the trigger fires every time any one of the targeted entities transitions. For example, if you monitor three motion sensors in the living room and someone walks past sensor 1, the automation fires. When they walk past sensor 2 a moment later, it fires again. Every individual event counts. -
First (
firstin YAML): the trigger fires only on the first transition in the targeted group, then waits until all targeted entities have reset before it fires again. For example, if you monitor the same three motion sensors, the automation fires when the first one picks up movement (someone entered the room). The other two firing afterward are ignored, so you get one notification per “someone walked in” event instead of three. -
All (
lastin YAML): the trigger fires only after the last targeted entity in the group has fired, meaning all of them are now in the expected state. For example, if you monitor the lights in the living room, bedroom, and hallway, the automation fires only once all three have turned off. This is useful for scenarios like “start the robot vacuum only after every light on the floor is off,” so you know the room is truly empty.
Good to know
- Battery stopped charging fires both when a device is unplugged and when it finishes charging naturally. If you only want to react when the battery is full, combine this trigger with a condition that checks the battery level.
- To react when a device starts charging, use Battery started charging.
- To fire when the battery level crosses a specific percentage, use Battery level crossed threshold instead.
- The trigger works with sensors that report a charging state, such as devices that expose a battery charging attribute.
Try it yourself
Ready to test this? Go to Settings > Automations & scenes, create a new automation, and add this trigger. Save the automation, then change the state of the targeted entity to watch the trigger fire on your actual entitiesAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service. [Learn more].
More examples
Real scenarios where this trigger fires in automations and scripts. Copy any example and adapt it to your setup.
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: notify when a tablet has finished charging
When your tablet finishes a charge cycle overnight, this automation lets you know it is ready to unplug, which helps avoid leaving it connected longer than necessary.
