As described in "https://www.zigbee2mqtt.io/information/groups.html"
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" }
If I send similar to the Zigbee Converter Node I get the error:
TypeError: Cannot read property 'endpoint' of undefined

With the command node the state of a group can be set, but not read.
