Driver API and source code available in liquidctl.driver.commander_core.
Changed in 1.11.0: the Corsair Commander Core XT is now supported.
Changed in 1.12.0: the Corsair Commander ST is now supported.
Currently, functionality implemented is listed here. More is planned to be added.
The device should be initialized every time it is powered on.

The Commander Core and ST currently can retrieve the pump speed, fan speeds, temperature of the water, and the temperature measured by the probe.
# liquidctl status
Corsair Commander Core (experimental)
├── Pump speed 2356 rpm
├── Fan speed 1 810 rpm
├── Fan speed 2 791 rpm
├── Fan speed 3 0 rpm
├── Fan speed 4 0 rpm
├── Fan speed 5 0 rpm
├── Fan speed 6 0 rpm
└── Water temperature 35.8 °C
The Core XT variant of the device is not meant for use with an AIO, so parameters relating to the pump are not present.
Corsair Commander Core XT (experimental)
├── Fan speed 1 2737 rpm
├── Fan speed 2 2786 rpm
├── Fan speed 3 0 rpm
├── Fan speed 4 0 rpm
├── Fan speed 5 0 rpm
└── Fan speed 6 0 rpm
New in 1.9.0.
Currently, the pump and each fan can be set to a fixed duty cycle.
# liquidctl set fan1 speed 70
^^^^ ^^
channel duty
Valid channel values on the Core (non-XT) and ST are pump, fanN, where 1 <= N <= 6 is the fan number.
On the Core XT, the pump channel is not present. The fans channel can be used to simultaneously
configure all fans.
In iCUE the pump can be set to different modes that correspond to a fixed percent that can be used in liquidctl. Quiet is 75%, Balanced is 85% and Extreme is 100%.
Note: the pump and some fans have a limit to how slow they can go and will not stop when set to zero. This is a hardware limitation that cannot be changed.
Note: the cooler's lights flash with every update. Due to limitations in both the device hardware and liquidctl, there currently is no way to solve this problem. For more information, see: #448.
