Prerequisites

Your LaMetric device must be powered on and connected to the same local network as Home Assistant. In most cases, the device is discovered automatically.

Configuration

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

LaMetric 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.

During setup, you can choose between two methods:

• Automatic: Sign in with your LaMetric account to let Home Assistant fetch your devices and their credentials for you.
• Manual: Enter the device’s hostname or IP address and API key. This method does not require a LaMetric account.

Actions

The LaMetric integration provides actions to interact with your LaMetric device(s). These actions can be used, for example, in automations.

Action: Chart

The lametric.chart action displays a chart on your LaMetric device.

Action: Message

The lametric.message action sends a message to your LaMetric device. These messages can be enriched with icons and sounds.

Notifications

You can send notifications to your LaMetric device using the Notifications integration.

Each LaMetric device added to Home Assistant has its own notify. action. The action name matches the name of your device as shown in your LaMetric account. For example, if you have a device called “My LaMetric”, the action becomes notify.my_lametric.

The notification action against a LaMetric device accepts the following additional optional parameters:

Data updates

The integration polls the LaMetric device every 30 seconds over the local network for the latest state.

Known limitations

• The integration communicates with the LaMetric device over the local network. If the device is not reachable, its entities become unavailable.
• When the LaMetric device is powered through a USB port on a computer, the display brightness is limited. For full brightness, use a proper USB charger.
• The list of supported sounds is fixed by the device firmware. Adding custom sounds is not possible.

Troubleshooting

The brightness does not go to 100%

When the LaMetric is powered through a USB port on a computer, the brightness is limited. To get the full brightness, use a proper USB charger.

Cannot connect during manual setup

If you see a “Cannot connect” error when adding the device manually, verify that:

1. The device is powered on and connected to your network.
2. The hostname or IP address you entered is correct.
3. The API key matches the one shown in the LaMetric developer portal.

Manual automatic import configuration

If you prefer not to use the Home Assistant account linking service, you can set up the LaMetric application manually.

However, at this point, it is easier to choose the Enter manually option during the integration setup. This avoids the use of the account linking service and does not require any of the steps below.

If you still want to set up your own LaMetric application for importing your LaMetric devices, use the following steps:

1. Sign in with your LaMetric account at developer.lametric.com.
2. Select Create and choose Notification app.
3. Fill in the form. You can put almost anything in the fields, they just need to be populated:
   • App Name: Home Assistant
   • Description: Home Assistant
   • Redirect URI: https://my.home-assistant.io/redirect/oauth
   • Privacy Policy: http://localhost/
   • Check the basic and read_devices permission boxes.
   • Select Save.
4. You will be directed to your Notification Apps list. Select Home Assistant and copy your Client ID and Client Secret.

You can then add the credentials to Application Credentials and set up the integration.

Removing the integration

This integration follows standard integration removal. No extra steps are required.

To remove an integration instance from Home Assistant

1. Go to Settings > Devices & services and select the integration card.
2. From the list of devices, select the integration instance you want to remove.
3. Next to the entry, select the three dots menu. Then, select Delete.
