This project is archived as Idasen Desk is now compatbile with Home Assistant and ESPHome Bluetooth Proxy (https://www.home-assistant.io/integrations/idasen_desk/).

This component creates a bluetooth bridge for an Ikea Idasen desk that uses a Linak controller with ESPHome and an ESP32 device.

Cover integration Linak Desk Card
Home Assistant Desk Controller

The desk is controlled using the cover integration or Linak Desk Card which is available in HACS in Home assistant.

Dependencies

Installation

You can install this component with ESPHome external components feature like this:

  1. external_components:
  2.   - source: github://j5lien/esphome-idasen-desk-controller@v4.0.0

For the first connection you will need to press the pairing button on the desk.

Configuration

BLE Client

You need first to configure ESPHome BLE Client (check the documentation for more information):

  1. esp32_ble_tracker:
  3. ble_client:
  4.   - mac_address: "00:00:00:00:00:00" # Replace with the desk bluetooth mac address
  5.     id: idasen_desk

On OSX, you can find the mac address of the desk by first connecting to it using a supported app (like Idasen Controller or Desk Remote Control), and then running this command in terminal:
system_profiler SPBluetoothDataType

Idasen Desk Controller

Then you need to enable this component with the id of the ble_client component:

  1. idasen_desk_controller:
  2.     # Reference to the ble client component id
  3.     # -----------
  4.     # Required
  5.     ble_client_id: idasen_desk
  6.     # Fallback to use only up and down commands (less precise)
  7.     # -----------
  8.     # Optional
  9.     only_up_down_command: false

Cover

Now you can add the cover component that will allow you to control your desk:

  1. cover:
  2.   - platform: idasen_desk_controller
  3.     name: "Desk"

Extra Desk informations

Using ESPHome BLE Client Sensor, you can expose more informations that doesn’t require this custom component.

This is an example that generates sensors that were available in previous versions:

  1. esp32_ble_tracker:
  3. globals:
  4.   # To store the Desk Connection Status
  5.   - id: ble_client_connected
  6.     type: bool
  7.     initial_value: 'false'
  9. ble_client:
  10.   - mac_address: "00:00:00:00:00:00"
  11.     id: idasen_desk
  12.     on_connect:
  13.       then:
  14.         # Update the Desk Connection Status
  15.         - lambda: |-
  16.             id(ble_client_connected) = true;
  17.         - delay: 5s
  18.         # Update desk height and speed sensors after bluetooth is connected
  19.         - lambda: |-
  20.             id(desk_height).update();
  21.             id(desk_speed).update();
  22.     on_disconnect:
  23.       then:
  24.         # Update the Desk Connection Status
  25.         - lambda: |-
  26.             id(ble_client_connected) = false;
  28. sensor:
  29.   # Desk Height Sensor
  30.   - platform: ble_client
  31.     type: characteristic
  32.     ble_client_id: idasen_desk
  33.     id: desk_height
  34.     name: 'Desk Height'
  35.     service_uuid: '99fa0020-338a-1024-8a49-009c0215f78a'
  36.     characteristic_uuid: '99fa0021-338a-1024-8a49-009c0215f78a'
  37.     icon: 'mdi:arrow-up-down'
  38.     unit_of_measurement: 'cm'
  39.     accuracy_decimals: 1
  40.     update_interval: never
  41.     notify: true
  42.     lambda: |-
  43.       uint16_t raw_height = ((uint16_t)x[1] << 8) | x[0];
  44.       unsigned short height_mm = raw_height / 10;
  46.       return (float) height_mm / 10;
  48.   # Desk Speed Sensor
  49.   - platform: ble_client
  50.     type: characteristic
  51.     ble_client_id: idasen_desk
  52.     id: desk_speed
  53.     name: 'Desk Speed'
  54.     service_uuid: '99fa0020-338a-1024-8a49-009c0215f78a'
  55.     characteristic_uuid: '99fa0021-338a-1024-8a49-009c0215f78a'
  56.     icon: 'mdi:speedometer'
  57.     unit_of_measurement: 'cm/min' # I'm not sure this unit is correct
  58.     accuracy_decimals: 0
  59.     update_interval: never
  60.     notify: true
  61.     lambda: |-
  62.       uint16_t raw_speed = ((uint16_t)x[3] << 8) | x[2];
  63.       return raw_speed / 100;
  65. binary_sensor:
  66.   # Desk Bluetooth Connection Status
  67.   - platform: template
  68.     name: 'Desk Connection'
  69.     id: desk_connection
  70.     lambda: 'return id(ble_client_connected);'
  72.   # Desk Moving Status
  73.   - platform: template
  74.     name: 'Desk Moving'
  75.     id: desk_moving
  76.     lambda: 'return id(desk_speed).state > 0;'

Troubleshooting

ESPHome lower than 1.19.0

Check the version v1.2.4 of this component

Not moving using cover component

If the desk is not moving using the cover component you can try to activate a fallback option only_up_down_command. It will only use up and down commands to control the desk height, it is less precise when you specify a target position.

  1. idasen_desk_controller:
  2.     ble_client_id: idasen_desk
  3.     only_up_down_command: true

Wifi deconnexion

If you experience Wifi deconnexion, try to activate the wifi fast connect option.

  1. wifi:
  2.   ssid: ...
  3.   password: ...
  4.   fast_connect: true

You can also try to set the power save mode option to none.

  1. wifi:
  2.   ssid: ...
  3.   password: ...
  4.   fast_connect: true
  5.   power_save_mode: none
