The Acaia integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] allows you to control Acaia scales through Home Assistant.

If your machine is within Bluetooth range to your Home Assistant host and the Bluetooth integration is fully loaded, the scale should be discovered automatically. If you are configuring the device manually, your scale needs to be turned on during setup.

Once the integration is set up, Home Assistant will try to connect to your scale every 15 seconds. This means there is sometimes a small delay between you turning the scale on and Home Assistant connecting to it.
