+title: "MQTT Select"
+description: "Instructions on how to interact with a device exposing a Select through MQTT from within Home Assistant."
+ha_category:
+  - Select
+ha_release: 2021.7
+ha_iot_class: Configurable
+ha_domain: mqtt
+---
+
+The `mqtt` Select platform allows you to integrate devices that might expose configuration options through MQTT into Home Assistant as a Select. Every time a message under the `topic` in the configuration is received, the select entity will be updated in Home Assistant and vice-versa, keeping the device and Home Assistant in sync.
+
+## Configuration
+
+To enable MQTT Select in your installation, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+select:
+    - platform: mqtt
+      command_topic: topic
+      name: "Test Select"
+      options:
+      	- "Option 1"
+      	- "Option 2"
+```
+
