Binding #

Ongoing discussion about this feature can be found here: https://github.com/Koenkk/zigbee2mqtt/issues/782

Zigbee has support for binding which makes it possible that devices can directly control each other without the intervention of zigbee2mqtt or any home automation software.

When to use this #

A use case for this is e.g. the TRADFRI wireless dimmer. Binding the dimmer directly to a bulb or group has the following advantages:

Commands #

Binding can be configured using the following topics:

Binding specific endpoint #

This is not applicable for most users

By default, the first endpoint is taken. In case your device has multiple endpoints, e.g. left and right. The following can be done to specifcy an endpoint:

Binding a group #

Steps to bind switch with groups, which some devices like IKEA E1743 require:

  1. Make a group to which you want to add your device(s) and light(s) in configuration.yaml, and give it a friendly_name. See https://www.zigbee2mqtt.io/information/groups.html.
  2. Make sure both the switch and devices are paired with your Zigbee2mqtt coordinator and send MQTT commands:
    • zigbee2mqtt/bridge/bind/switchname payload: GROUPNAME
    • zigbee2mqtt/bridge/group/groupname/add payload: DEVICENAME (repeat for multiple devices)
  3. If this doesn’t work, send MQTT commands again and if that doesn’t work, reset switch and light and try again.

Devices #

Not all devices support this, it basically comes down to the Zigbee implementation of the device itself. Check the device specific page for more info (can be reached via the supported devices page)

Report #

When using this feature you are probably also interested in using the report feature. This allows you to get state changes when e.g. a bulb state changes by a bound dimmer. Read more about it here Report.
