Notes

Pairing

  1. If there are blinking LEDs wait until they don’t blink anymore — the device is in some mode we don’t want it to be.
  2. Press both buttons of the top row (or sole row for Model 6735) until the LEDs gleam permanently. They will blink alternately at first but keep the buttons pressed until really both lights are constantly illuminated. Then release the buttons. The LEDs should still glow.
  3. Now press both buttons again briefly. After about 1..2 seconds they will fade-glow; and your bridge should now instantly find it.

Known issues

Bottom row of 4-gang device not bound

It may occur that the bottom row of the 4-gang device 6737 does not work like the other ones, i.e. does not emit the actions (see related discussion #7009open in new window). The reason is not fully understood yet, however it can be worked around by unbinding all four endpoints and re-binding them manually one after another:

Source EPDestinationDestination EPClusters
10Coordinator16710 U: LevelCtrl
6711 U: OnOff [^1]
11Coordinator1LevelCtrl
12Coordinator1LevelCtrl
13Coordinator1LevelCtrl

*[EP]: Endpoint [^1]: Depending on whether the control panel sits on a 6710 U (power supply) or 6711 U (relay), OnOff respectively LevelCtrl shall be used.

Action values

This device send the following action values in its payload:

Left buttons(long-hold-release)Right buttons
row_1_off
row_1_down
row_1_stoprow_1_on
row_1_up
row_2_off
row_2_down
row_2_stoprow_2_on
row_2_up
row_3_off
row_3_down
row_3_stoprow_3_on
row_3_up
row_4_off
row_4_down
row_4_stoprow_4_on
row_4_up

Briefly pressing and releasing a button triggers the off resp. on actions for the given row, long-pressing triggers the down/up state respectively (after about one second). When releasing then, a stop will be issued with no distinction between the left or right button.

Options

How to use device type specific configuration

  • transition: Controls the transition time (in seconds) of on/off, brightness, color temperature (if applicable) and color (if applicable) changes. Defaults to 0 (no transition). The value must be a number with a minimum value of 0

  • legacy: Set to false to disable the legacy integration (highly recommended), will change structure of the published payload (default true). The value must be true or false

Switch

The current state of this switch is in the published state under the state property (value is ON or OFF). To control this switch publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"state": "ON"}, {"state": "OFF"} or {"state": "TOGGLE"}. To read the current state of this switch publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"state": ""}.

Action (enum)

Triggered action (e.g. a button click). Value can be found in the published state on the action property. It's not possible to read (/get) or write (/set) this value. The possible values are: row_1_on, row_1_off, row_1_up, row_1_down, row_1_stop, row_2_on, row_2_off, row_2_up, row_2_down, row_2_stop, row_3_on, row_3_off, row_3_up, row_3_down, row_3_stop, row_4_on, row_4_off, row_4_up, row_4_down, row_4_stop.

Linkquality (numeric)

Link quality (signal strength). Value can be found in the published state on the linkquality property. It's not possible to read (/get) or write (/set) this value. The minimal value is 0 and the maximum value is 255. The unit of this value is lqi.
