Linak / IKEA IDÅSEN Desk Controller - Bluetooth C# Library

This is library and a CLI (command line interface) tool to control Linak desks with bluetooth support. This unit is used in IKEA IDÅSEN desks. It should work fine with other LINAK desks, but I have not tested it.

Remark: Only IKEA IDÅSEN desks got interface made by LINAK. Cheaper desks from IKEA use different manufacturer.

Written in .NET/C#.

Pull requests welcome.

Missing Features

• Pairing process.
• User identification and desk offsets.

Setting Powershell Alias

You can create command aliases like desk-up or desk-down to perform move command.

# Edit profile file
notepad $PROFILE

# Add any custom functions you need. For example:
Function desk-down() { & 'E:\programs\linak-desk\LinakDeskCli' move FFFFFFFFFFFF m1 }
Function desk-up() { & 'E:\programs\linak-desk\LinakDeskCli' move FFFFFFFFFFFF m2 }
