Help setting up the YLKG07YL, YLKG08YL dimmer switches

[Jozzy]

Hello! I would like to get some help

I’m sorry, could you explain where should I put this?: (When I try to the entities card: I can’t save it. Or this one is goes too in the configuration.yaml?)

alias: ble dimmer automation
description: ""
trigger:
  - platform: state
    entity_id:
      - sensor.ble_dimmer_dimmer_yeelight
    attribute: last_packet_id
condition: []
action:
  - choose:
      - conditions:
          - condition: state
            entity_id: sensor.ble_dimmer_dimmer_yeelight
            attribute: last_type_of_press
            state: short press
        sequence:
          - service: light.toggle
            data: {}
            target:
              entity_id: light.yeelink_ceiling5_41d0_light
      - conditions:
          - condition: state
            entity_id: sensor.ble_dimmer_dimmer_yeelight
            attribute: last_type_of_press
            state: rotate right
        sequence:
          - service: light.turn_on
            data:
              brightness_step_pct: >-
                {{ state_attr('sensor.ble_dimmer_dimmer_yeelight',
                'dimmer_value') | int*5 }}
            target:
              entity_id: light.yeelink_ceiling5_41d0_light
      - conditions:
          - condition: state
            entity_id: sensor.ble_dimmer_dimmer_yeelight
            attribute: last_type_of_press
            state: rotate left
        sequence:
          - service: light.turn_on
            data:
              brightness_step_pct: >-
                {{ state_attr('sensor.ble_dimmer_dimmer_yeelight',
                'dimmer_value') | int*-5 }}
            target:
              entity_id: light.yeelink_ceiling5_41d0_light
mode: single

I changed the entity names for my setup.

Go to Settings → automations → “create automation” → “create new automation”, now on the top right, you see the 3 dots, click those → edit in Yaml → paste my code there, hit save.

Now go back to “automations” and you should see a new automation there.
Click on it, and you can either use the visual editor, or the Yaml to edit it.

For adding the ble device, I added it to my configuration.yaml (file editor → /config/configuration.yaml)

How fast does the battery drain for you guys?

Same here. Only RSSI and no sensors. Have you been successful yet?

Hello everyone,

I post here because lot of people having trouble with their YLKG07YL dimmer, and I was like you, been nuts to have beacon_key or adding it in home assistant… take me hours of digging to fix it !

Here what i’ve test, done, and check

First of all, recover the MAC adresse of the device with phone app for me “A4:C1:38:35:4F:62”

Be carefull, pressing the pariring button during 20s will change this MAC address

After that use the method 5 from Passive BLE integration FAQ :

5. get_beacon_key python script

FAQ

In my case :

wget https://raw.githubusercontent.com/custom-components/ble_monitor/master/custom_components/ble_monitor/ble_parser/get_beacon_key.py
apt-get install python3-pip libglib2.0-dev
pip3 install bleak asyncio
python3 get_beacon_key.py <A4:C1:38:35:4F:62> <950>

Be sure to use a relevant linux, bluetooth and python configuration

If you can’t connect to your device or if it’s say “Disconnected!”, try this before launching the script :

hciconfig hci0 up

After that you will have something like this :

notifyData: ‘ce6b3f6f42adc97421cf015f’
cipheredRes: ‘00a486f5ff013ed04322f4e4’
randomToken: ‘00a486f5ff013ed04322f4e4’
Successful authentication!
beaconKey: ‘acec46f9b751b694e8167d02’
firmware_version: '2.0.0_0004

Now you have you beacon_key, you can configure the BLE device to HASS on configuration.yaml

But cherry on the cake you have to add eight f to the end of the encryption_key

ble_monitor:
  discovery: true
  devices:
    - mac: 'A4:C1:38:35:4F:62'
      name: 'dimmer_yeelight'
      encryption_key: 'acec46f9b751b694e8167d02ffffffff'
      reset_timer: 1

Hope it will help ! Thanks to [frickeo]

Have you come across any BLE switches or dimmers that work well with ESPHome?

hi, I didn’t understand how to get the beacon key?
