Notes

You can calibrate your device (to enable position support) by closing the shutter (or opening it if your cover position is inverted) and pressing both the up and down buttons for about 5 seconds until you see a blinking yellow light. The shutter will begin calibrating itself and will open and close a few times (this process takes a few minutes to complete).

OTA updates

This device supports OTA updates, for more information see OTA updates.

Options

How to use device type specific configuration

invert_cover: Inverts the cover position, false: open=100,close=0, true: open=0,close=100 (default false). The value must be true or false
cover_position_tilt_disable_report: Do not publish set cover target position as a normal 'position' value (default false). The value must be true or false
identity_effect: Defines the identification effect to simplify the device identification. Example:

identity_effect:
  effect: blink 3 # allowed: 'blink 3', 'fixed', 'blink green', 'blink blue'
  color: red # allowed: 'default', 'red', 'green', 'blue', 'lightblue', 'yellow', 'pink', 'white'

Exposes

Cover

The current state of this cover is in the published state under the state property (value is OPEN or CLOSE). To control this cover publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"state": "OPEN"}, {"state": "CLOSE"}, {"state": "STOP"}. It's not possible to read (/get) this value. To change the position publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"position": VALUE} where VALUE is a number between 0 and 100.

Action (enum)

Triggered action (e.g. a button click). Value can be found in the published state on the action property. It's not possible to read (/get) or write (/set) this value. The possible values are: identify, open, close, stop, moving, stopped.

Identify (enum)

Blinks the built-in LED to make it easier to identify the device. Value will not be published in the state. It's not possible to read (/get) this value. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"identify": NEW_VALUE}. The possible values are: identify.

Led in dark (binary)

Enables the built-in LED allowing to see the switch in the dark. Value can be found in the published state on the led_in_dark property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"led_in_dark": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"led_in_dark": NEW_VALUE}. If value equals ON led in dark is ON, if OFF OFF.

Led if on (binary)

Enables the LED on activity. Value can be found in the published state on the led_if_on property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"led_if_on": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"led_if_on": NEW_VALUE}. If value equals ON led if on is ON, if OFF OFF.

Calibration mode (enum)

Defines the calibration mode of the switch. (Caution: Changing modes requires a recalibration of the shutter switch!). Value can be found in the published state on the calibration_mode property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"calibration_mode": ""}. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"calibration_mode": NEW_VALUE}. The possible values are: classic_nllv, specific_nllv, up_down_stop, temporal, venetian_bso.

Linkquality (numeric)

Link quality (signal strength). Value can be found in the published state on the linkquality property. It's not possible to read (/get) or write (/set) this value. The minimal value is 0 and the maximum value is 255. The unit of this value is lqi.
