hi can you controll two desks with one esp32? i see a way to modifying the ID for the other components except the idasen_desk_controller component
iām afraid, a lot of users (including me) are facing issues with the ble_client in ESPHome connecting to idasenās controller. it just connects, but does not pair. the desk keeps blinking even after connecting and then the esphome logs show it got disconnected and then cannot connect as the desk goes out of pairing mode. this situation stays the same irrespective of whether wifi is enabled or not.
using a nodemcu esp32s board (ai thinker).
@j5lien please help whenever you get back from vacation
Excellent find. Just for completeness can you post your working config?
sure this is my full working config. bluetooth_callback does not work. if enabled, this component will go into an infinite loop when trying to move the desk to a set position because it is not receiving any BLE notifications from the desk about its height. so just set it to off and then the component will get height from the same service characteristic which is used to change the height.

Thanks @j5lien for writing this integration. I did a few issues like other trying to get ESPHome to talk to the Linak controller but after a few hours (days). I was able to get the integration working perfectly with Home Assistant.
My Steps:
I know some people have had issues with different versions of ESP32, I purchased mine off Amazon (https://www.amazon.com.au/gp/product/B097DCN76N/) and seems to work perfectly.
I had lots of issues with paring the desk using āesp32_ble_trackerā component. So, I switched to the older version which uses the BLE Arduino library. I found the mac address of the desk using an android application āBLE Scannerā and paired the desk to the ESP32. Once the pairing process was complete and I could control the desk. I switched to the latest version that uses esp32_ble_tracker and the connection has been rock steady.
Code for paring:
esphome:
name: sam-idasen
platform: ESP32
board: esp32dev
libraries:
- "ESP32 BLE Arduino"
# Enable logging
logger:
wifi:
ssid: !secret IoT_ssid
password: !secret IoT_password
# Enable fallback hotspot (for captive portal) in case wifi connection fails
ap:
ssid: "ESPHome $friendly_name"
password: !secret ap_password
api:
password: !secret api_ota_Password
ota:
password: !secret api_ota_Password
external_components:
- source: github://j5lien/[email protected]
idasen_desk_controller:
mac_address: "00:00:00:00:00:00"
sensor:
- platform: idasen_desk_controller
desk_height:
name: "Desk Height"
binary_sensor:
- platform: idasen_desk_controller
name: "Desk Connection"
type: CONNECTION
- platform: idasen_desk_controller
name: "Desk Moving"
type: MOVING
cover:
- platform: idasen_desk_controller
name: "Desk"
Once paring is complete and the desk responds to ESP Home/Home Assistant, update the code to the latest version:
esphome:
name: sam-idasen
platform: ESP32
board: esp32dev

friendly_name: Sam Idasen Desk

Thanks so much to @j5lien for his library and esphome compatibility!
Finally! This work around made my project finally working!
I transformed this old 70s alarm clock, to my preset, controller idasen desk.

Thanks a bunch Sam. Your method worked for me as well! However, when I update ESPHome (Docker) to the latest version, my desk is in an infinite loop and I cannot control it anymore. However, when I stay at 2021.10.0 no problems at all, but I canāt see the desk height or desk speedā¦ Are you having the same problems?
Hi Justin,
I am not having any issues with mine. Seems to work well and very responsive.
Regards,
Sam
Since my message to you, Iāve downgraded to 2021.10.0 and upgraded back again to the latest tag. Everythingās running buttery smooth now, I can see the heights and I even mapped a W2049 Ikea controller to the desk via ControllerX. This feels so next level instead of relying on an app (oh the irony with HA) or the desk controller itself.

When i try loading it i get error [15:06:17][W][idasen_desk_controller:104]: Error reading char at handle 26, status=5 and i dont know why, it seems to be an authentication error
i tried using 1.2.0 but i get the error āidasen_desk_controller is not a correct platformā and āThis component requred ble clientā
In case anyone is looking for a solution NOT using an ESP32 device, but rather a good old bluetooth dongle, Iāve built this https://github.com/maxime1992/linak-2-mqtt which let me integrate with HA and the linak desk card. All the info should be written in the README

Can you please help? Error reading char at handle 26, status=5 Ā· Issue #42 Ā· j5lien/esphome-idasen-desk-controller Ā· GitHub
probably your desk is stuck and need to be reset.
Unplug, wait some seconds, plug again and set all down, than all up.

Iām having a problem with my Linak tv lift (which is basically a desk) I followed the installation but I canāt get the lift to move. In the log i see [10:33:58][D][idasen_desk_controller:217]: Update Desk - Move from 100 to 0
a lot, but it just doesnāt move! Can anybody here help me?
The full log is: INFO Reading configuration /config/esphome/tv-lift.yaml...INFO Starting log ou - Pastebin.com
Can these integration be updated using new Bluetooth integration since 2022.8?
