# Assign a meter to a space

> Links a meter to a space.

> [!NOTE]
>
> The meter and the space must be in the building. The body must hold the same `buildingId` as the path. Sending the same assignment again is not an error.

> [!WARNING]
>
> With `exclusive` set to `true`, KODE removes the meter's existing space assignments before it adds the new one. Leave `exclusive` out unless you mean to replace them.

> [!NOTE]
>
> The response is `204` with no body. To remove an assignment, use [Remove a meter assignment](https://docs.kodelabs.com/products/kode-api/api-reference/meters/remove-a-meter-assignment.md).
