Features

Ads the standing desk as a controllable blind to the home app. You can then adjust the desk height by setting that blind. Unfortinatly there is nothing like a desk or similar in homekit, so this is currently the best solution to freely adjust the height.

I would recomment to set some home scenes for your standing and sitting height, with your prefered value, e.g.: Standing: blind 65% open Sitting: blind 25% open Using scenes you can adjust your desk using scenes like "Hey Siri, activate sitting".

How it works

The plugin calculates the height in mm from the value set by homekit and calls the idasen-controller implementation with the height in mm. The calculation is taken from homebridge_idasen. It can also get the actual desk height from the controller. The actual height will be calculated using the calculations mentioned before and will be returned to homekit as a percentage.

Special thanks to idasen-controller for his hard work! This made my plugin possible in the first place. Special thanks to homebridge-homebridge_idasen-cmd for giving me the idea to spawn a child_process to control the desks.
