Work modes

By default remote works as custom switch, with multiple clicks, but this behavior has own drawback. In order to detect multiple clicks, remote sends commands with 300ms delay. You can change this behavior by 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 behavior.

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'
