busylight_core.vendors.muteme.mutesync

MuteSync status light and button implementation.

Classes

busylight_core.vendors.muteme.mutesync.MuteSync

MuteSync(hardware, *, reset=False, exclusive=True)

Bases: Light

MuteSync status light and button controller.

The MuteSync is a USB-connected device that combines button functionality with status light capabilities for meeting control.

Initialize a Light with the given hardware information.

:param: reset - bool - reset the hardware to a known state :param: exclusive - bool - acquire exclusive access to the hardware
