The mqtt cover platform allows you to control an MQTT cover (such as blinds, a rollershutter or a garage door).

Configuration

The device state (open, opening, closed or closing) will be updated only after a new message is published on state_topic matching state_open, state_opening, state_closed or state_closing. If these messages are published with the retain flag set, the cover will receive an instant state update after subscription and Home Assistant will display the correct state on startup. Otherwise, the initial state displayed in Home Assistant will be unknown. state_topic can only manage state_open, state_opening, state_closed and state_closing. No percentage positions etc.

For this purpose is position_topic which can set state of the cover and position. Default setting are 0 means the device is closed and all other intermediate positions means the device is open. position_topic is managed by position_open and position_closed You can set it up in opposite way as well. If position topic is defined than state topic is ignored.

If a state topic and position topic are not 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 an availability_topic 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 payload_not_available to 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:

# Example configuration.yaml entry
cover:
  - platform: mqtt

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"
