Configuration of device attributes #

By publishing to zigbee2mqtt/[FRIENDLY_NAME]/set various device attributes can be configured:

{
    "options":{
        "reverse_direction": xxx,
        "auto_close": xxx
    }
}

• reverse_direction: (true/false, default: false). Device can be configured to act in an opposite direction.
• auto_close: (true/false, default: true). Enables/disabled auto close

You can send a subset of options, all options that won’t be specified will be revered to default.

After changing reverse_direction you will need to fully open and fully close the curtain so the motor will re-detect edges. reverse_direction will get new state only after this recalibration.

Manual Home Assistant configuration #

Although Home Assistant integration through MQTT discovery is preferred, manual integration is possible with the following configuration:
