The mqtt cover platform allows you to control an MQTT cover (such as blinds, a roller shutter or a garage door).
Configuration
A cover entity can be in states (open, opening, closed or closing).
If a state_topic is configured, the entity's state will be updated only after an MQTT message is received on state_topic matching state_open, state_opening, state_closed or state_closing. For covers that only report 3 states (opening, closing, stopped), a state_stopped state can be configured to indicate that the device is not moving. When this payload is received on the state_topic, and a position_topic is not configured, the cover will be set to state closed if its state was closing and to state open otherwise. If a position_topic is set, the cover's position will be used to set the state to either open or closed state.
If the cover reports its position, a position_topic can be configured for receiving the position. If no state_topic is configured, the cover's state will be set to either open or closed when a position is received.
If the cover reports its tilt position, a tilt_status_topic can be configured for receiving the tilt position.
If position topic and state topic are both defined, the device state (open, opening, closed or closing) will be set by the state topic and the cover position will be set by the position topic.
If neither a state topic nor a position topic are defined, the cover will work in optimistic mode. In this mode, the cover will immediately change state (open or closed) after every command sent by Home Assistant. If a state topic/position topic is defined, the cover will wait for a message on state_topic or position_topic.
Optimistic mode can be forced, even if a state_topic / position_topic is defined. Try to enable it if experiencing incorrect cover operation (Google Assistant gauge may need optimistic mode as it often send request to your Home Assistant immediately after send set_cover_position in which case MQTT could be too slow).
The mqtt cover platform optionally supports a list of availability topics to receive online and offline messages (birth and LWT messages) from the MQTT cover device. During normal operation, if the MQTT cover device goes offline (i.e., publishes a matching payload_not_available to any availability topic), Home Assistant will display the cover as "unavailable". If these messages are published with the retain flag set, the cover will receive an instant update after subscription and Home Assistant will display correct availability state of the cover when Home Assistant starts up. If the retain flag is not set, Home Assistant will display the cover as "unavailable" when Home Assistant starts up.
To use your MQTT cover in your installation, add the following to your configuration.yaml file:

MQTT cover expects position and tilt values to be in range of 0 to 100, where 0 indicates closed position and 100 indicates fully open position.
If position min or max are set to a different range (e.g. 40 to 140), when sending command to the device the range will be adjusted to the device range (position 0 will send a value of 40 to device) and when position payload is received from the device it will be adjusted back to the 0 to 100 range (device value of 40 will report cover position 0).
min and max can also be used to reverse the direction of the device, if min is set to 100 and max is set to 0 device operation will be inverted (e.g. when setting position to 40, a value of 60 will be sent to device).

Configuration for disabling cover commands
The example below shows a configuration for a cover that does not have a close command.
Setting payload_close empty or to null disables the close command and will not show the close button.
{% raw %}
# Example configuration.yaml entry
mqtt:
cover:
- payload_open: "on"
payload_close:
payload_stop: "on"
{% endraw %}
The following commands can be disabled: open, close, stop by overriding their payloads: payload_open, payload_close, payload_stop
For auto discovery message the payload needs to be set to null, example for cover without close command:
{% raw %}
{
"cover": [
{
"payload_open": "on",
"payload_close": null,
"payload_stop": "on"
}
]
}
{% endraw %}
Full configuration using entity_id- variable in the template
The example below shows an example of how to correct the state of the blind depending if it moved up, or down.
{% raw %}
# Example configuration.yaml entry
mqtt:
cover:
- name: "MQTT Cover"
command_topic: "home-assistant/cover/set"
state_topic: "home-assistant/cover/state"
position_topic: "home-assistant/cover/position"
set_position_topic: "home-assistant/cover/position/set"
payload_open: "open"
payload_close: "close"
payload_stop: "stop"
state_opening: "open"
state_closing: "close"
state_stopped: "stop"
optimistic: false
position_template: |-
{% if not state_attr(entity_id, "current_position") %}
{{ value }}
{% elif state_attr(entity_id, "current_position") < (value | int) %}
{{ (value | int + 1) }}
{% elif state_attr(entity_id, "current_position") > (value | int) %}
{{ (value | int - 1) }}
{% else %}
{{ value }}
{% endif %}
{% endraw %}
Full configuration using advanced templating
The example below shows a full example of how to set up a venetian blind which has a combined position and tilt topic. The blind in the example has moveable slats which tilt with a position change. In the example, it takes the blind 6% of the movement for a full rotation of the slats.
Following variable might be used in position_template, set_position_template, tilt_command_template and tilt_status_template, json_attributes_template (only entity_id).
entity_id- The ID of the entity itself. It can be used to reference its attributes with the help of the states template function.position_openposition_closedtilt_mintilt_max

Testing your configuration
To test, you can use the command line tool mosquitto_pub shipped with mosquitto or the mosquitto-clients package to send MQTT messages. This allows you to operate your cover manually:
mosquitto_pub -h 127.0.0.1 -t home-assistant/cover/set -m "CLOSE"
