| MQTT Select | Instructions on how to interact with a device exposing a Select through MQTT from within Home Assistant. |
|
2021.7 | Configurable | 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:
# Example configuration.yaml entry
mqtt:
select:
- command_topic: topic
name: "Test Select"
options:
- "Option 1"
- "Option 2"
{% details "Previous configuration format" %}
The configuration format of manual configured MQTT items has changed.
The old format that places configurations under the select platform key
should no longer be used and is deprecated.
The above example shows the new and modern way, this is the previous/old example:
select:
- platform: mqtt
command_topic: topic
name: "Test Select"
options:
- "Option 1"
- "Option 2"
{% enddetails %}
