Busch-Jaeger switch 6737 missing enities

Configuration Zigbee
1

Hello i am trying to switch from deconz to Z2M. (add-on in home assistant)
Now i have paired one Busch-Jaeger switch 6737 with dim module to Z2M
But i cannot dim the light bulb that is connected to the switch from Z2M.
Also there is no brightness available in Home assistant.
i can turn on/off the lamp from home assistant
also the actions of the buttons are coming to home assistant.

if i use node-red i can send {“brightness_relay”: “255”} to the topic
zigbee2mqtt/FRIENDLY_NAME/set
and change the brightness

This is what Z2M shows:

{
"brightness_relay": 254,
"linkquality": 94,
"state": "ON",
"state_relay": "ON",
"action": null
}

but in home assistant no brightness entity is created

is there a way to add these variabels manually to home assitant ?

This sort of device publishes an action when you press a button. The Actions are described here

https://www.zigbee2mqtt.io/devices/6735_6736_6737.html#action-enum

So in HA you have to automate based on that action.

Here is an example from a different device, but they all work this way:

alias: Dim Up Dining Lights
description: ""
trigger:
  - platform: device
    domain: mqtt
    device_id: 44f8adc86e1f6ff305055755fb569a28
    type: action
    subtype: button_6_single
    discovery_id: 0x04cf8cdf3c791f3f action_button_6_single
condition: []
action:
  - service: light.turn_on
    target:
      entity_id: light.dining_table_lights
    data:
      transition: 3
      brightness_step_pct: 10
mode: single

Although I have posted yaml, this is entirely do-able from the autmation UI.

Thanks for the response,

There are 3 Switch modules 1,2 and 4 buttons

which can be combined with 3 modules.

Power supply, Dim and Relay module.

If use a power supply only actions can be used as described in your link.

if used a Relay module Button No. 1 is used for switch on/off the connected light.

If used a dim module Button No. 1 is used for switch on/off the connected light.

And press long up dim up press long down dim down.

If I publish a message to “brightness_relay”: 254 I can dim the light.

If a publish a message to “state”: “ON” I can switch the light on/off

The “state_relay”: “ON” gives the actual state of the light on the module

Can I create a light in configuraton yaml with these settings ?

Now the auto creation is not working, now I have this:

Actions are coming to home assistant

The state is created as an entity, I can use this to switch the light on/off

Downside is that this is not the current state of the module, this is pulished in “state_relay”: “ON”

Do you have legacy set to true or false?

Legacy is set to False

i have create 3 new lights and added the following:
Made a new folder

/config/mqtt/

Changed the following in configuration.yaml

mqtt: !include_dir_merge_named mqtt/

Then i ceated a new fille in /config/mqtt/

/config/mqtt/mqtt_light.yaml

There i added the following:

# Example mqtt.yaml entry
light:
  - name: "Overkapping wand template mqtt"
    state_topic: "zigbee2mqtt/Woonkamer overkapping wandlamp Z2M"
    command_topic: "zigbee2mqtt/Woonkamer overkapping wandlamp Z2M/set/state"
    brightness_state_topic: "zigbee2mqtt/Woonkamer overkapping wandlamp Z2M"
    brightness_command_topic: "zigbee2mqtt/Woonkamer overkapping wandlamp Z2M/set/brightness_relay"
    state_value_template: "{{ value_json.state_relay }}"
    brightness_value_template: "{{ value_json.brightness_relay }}"
    qos: 0
    payload_on: "ON"
    payload_off: "OFF"
    optimistic: false
  - name: "Keuken template mqtt"
    state_topic: "zigbee2mqtt/Keuken licht keuken Z2M"
    command_topic: "zigbee2mqtt/Keuken licht keuken Z2M/set/state"
    brightness_state_topic: "zigbee2mqtt/Keuken licht keuken Z2M"
    brightness_command_topic: "zigbee2mqtt/Keuken licht keuken Z2M/set/brightness_relay"
    state_value_template: "{{ value_json.state_relay }}"
    brightness_value_template: "{{ value_json.brightness_relay }}"
    qos: 0
    payload_on: "ON"
    payload_off: "OFF"
    optimistic: false
  - name: "Tafel template mqtt"
    state_topic: "zigbee2mqtt/Woonkamer licht tafel Z2M"
    command_topic: "zigbee2mqtt/Woonkamer licht tafel Z2M/set/state"
    brightness_state_topic: "zigbee2mqtt/Woonkamer licht tafel Z2M"
    brightness_command_topic: "zigbee2mqtt/Woonkamer licht tafel Z2M/set/brightness_relay"
    state_value_template: "{{ value_json.state_relay }}"
    brightness_value_template: "{{ value_json.brightness_relay }}"
    qos: 0
    payload_on: "ON"
    payload_off: "OFF"
    optimistic: false

Looks like it is working now, downside the state / brightness feedback is slow +/- 3 sec.
