Settings

In zigbee2mqtt you could change the setting at Exposes tab.

Work modes

By default remote works as a custom switch, with multiple clicks, but this behaviour has its drawback. To detect multiple clicks, the remote sends commands with a 300ms delay. You can change this behaviour by the cost of double/triple/etc clicks.

To do that you need to change

ZCL_CLUSTER_ID_GEN_ON_OFF_SWITCH_CONFIG cluster ATTRID_ON_OFF_SWITCH_TYPE attribute

Values are:

ON_OFF_SWITCH_TYPE_MOMENTARY (0) -> no delay, but no multiple clicks, only single

mosquitto_pub -t "zigbee2mqtt/FN/BUTTON_NUM/set/switch_type" -m '0'

ON_OFF_SWITCH_TYPE_MULTIFUNCTION (2) -> 300ms delay, full set of clicks

mosquitto_pub -t "zigbee2mqtt/FN/BUTTON_NUM/set/switch_type" -m '2'

ONOFF cluster binding

By default command is TOGGLE, but you can change this behaviour.

Change ZCL_CLUSTER_ID_GEN_ON_OFF_SWITCH_CONFIG clusters attribute ATTRID_ON_OFF_SWITCH_ACTIONS

ON_OFF_SWITCH_ACTIONS_ON

mosquitto_pub -t "zigbee2mqtt/FN/BUTTON_NUM/set/switch_actions" -m '0'

ON_OFF_SWITCH_ACTIONS_OFF

mosquitto_pub -t "zigbee2mqtt/FN/BUTTON_NUM/set/switch_actions" -m '1'

ON_OFF_SWITCH_ACTIONS_TOGGLE (default value)

mosquitto_pub -t "zigbee2mqtt/FN/BUTTON_NUM/set/switch_actions" -m '2'
