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

The desk is controlled using the cover integration or Linak Desk Card which is available in HACS in Home assistant.
- This component requires an ESP32 device.
- ESPHome 2021.10.0 or higher.
You can install this component with ESPHome external components feature like this:
external_components:
- source: github://j5lien/[email protected]
For the first connection you will need to press the pairing button on the desk.
You need first to configure ESPHome BLE Client (check the documentation for more information):
esp32_ble_tracker:
ble_client:
- mac_address: "00:00:00:00:00:00" # Replace with the desk bluetooth mac address
id: idasen_deskOn 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
Then you need to enable this component with the id of the ble_client component:
idasen_desk_controller:
# Reference to the ble client component id
# -----------
# Required
ble_client_id: idasen_desk
# Fallback to use only up and down commands (less precise)
# -----------
# Optional
only_up_down_command: falseNow you can add the cover component that will allow you to control your desk:
cover:
- platform: idasen_desk_controller
name: "Desk"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:
esp32_ble_tracker:
globals:
# To store the Desk Connection Status
- id: ble_client_connected
type: bool
initial_value: 'false'
ble_client:
- mac_address: "00:00:00:00:00:00"
id: idasen_desk
on_connect:
then:
# Update the Desk Connection Status
- lambda: |-
id(ble_client_connected) = true;
- delay: 5s
# Update desk height and speed sensors after bluetooth is connected
- lambda: |-
id(desk_height).update();
id(desk_speed).update();
on_disconnect:
then:
# Update the Desk Connection Status
- lambda: |-
id(ble_client_connected) = false;
sensor:

return raw_speed / 100;
binary_sensor:

id: desk_connection
lambda: 'return id(ble_client_connected);'
# Desk Moving Status
- platform: template
name: 'Desk Moving'
id: desk_moving
lambda: 'return id(desk_speed).state > 0;'Check the version v1.2.4 of this 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.
