Groups

Zigbee2mqtt has support for Zigbee groups. By using Zigbee groups you can control multiple devices simultaneously with one command.

NOTE: to use groups, at least firmware version 20181224 is required! (available here)

Configuration

Add the following to your configuration.yaml.

groups:
  # ID, each group should have a different numerical ID
  '1':
    # Name which will be used to control the group
    friendly_name: group_1

Commands

The group of a node can be configured using the following commands:

• zigbee2mqtt/bridge/group/[GROUP_FRIENDLY_NAME]/add with payload DEVICE_FRIENDLY_NAME will add a device to a group.
• zigbee2mqtt/bridge/group/[GROUP_FRIENDLY_NAME]/remove with payload DEVICE_FRIENDLY_NAME will remove a device from a group.
• zigbee2mqtt/bridge/group/[GROUP_FRIENDLY_NAME]/remove_all with payload DEVICE_FRIENDLY_NAME will remove a device from all groups.

Controlling

Controlling a group is similar to controlling a single device. For example to turn on all devices that are part of group send a MQTT message to zigbee2mqtt/[GROUP_FRIENDLY_NAME]/set with payload:

{
  "state": "ON",
}

How do groups work?

By using the above add command above, a device will be added to a group. The device itself is responsible for storing to which groups it belongs. Others, e.g. the coordinator, do not have knowledge to which device a groups belongs.

When using the set command, e.g. to turn on all devices in a group, a broadcast request is send to *all devices in the network. The device itself then determines if it belongs to that group and if it should execute the command.
