# Binding
|
||
|
|
*This is an experimental feature, ongoing discussion 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:
|
||
|
|
- Smoothness; this will greatly improve the dimming feedback as the dimmer directly dims the bulb and thus does not have to make the MQTT/home automation software roundtrip.
|
||
|
|
- It will work even when home automation software, zigbee2mqtt or the coordinator is down.
|
||
|
|
|
||
|
|
## Commands
|
||
|
|
Binding can be configured using the following topics:
|
||
|
|
|
||
|
|
- `zigbee2mqtt/bridge/bind/[SOURCE_DEVICE_FRIENDLY_NAME]` with payload `TARGET_DEVICE_FRIENDLY_NAME` will bind the source device to the target device. In the above example, the TRADFRI wireless dimmer would be the source device and the bulb the target device.
|
||
|
|
- `zigbee2mqtt/bridge/unbind/[SOURCE_DEVICE_FRIENDLY_NAME]` with payload `TARGET_DEVICE_FRIENDLY_NAME` will unbind the devices.
