RE of lghub_agent.arm64 revealed that LGHUB's service-layer handler for 0x0618 HeadsetBatterySaverMode (on_headset_battery_saver_set_handler @ 0x100c21790) compares the requested new state against its cached current state and ONLY invokes the devio SetEcoModeState write on a genuine transition. Wire format is confirmed 0/1 (canonical doc correct); the G522 firmware rejects no-op writes with device-specific NACK 0x0B. BooleanValidator's prepare_write already contains the "skip if same as current" branch — it just fires only when current_value is supplied, which requires needs_current_value=True. For default-mask (0xFF) validators, needs_current_value defaults to False so Setting.write skips the pre-read and prepare_write gets current_value=None. HeadsetEcoMode now builds its validator explicitly and forces needs_current_value=True so Setting.write reads first, compares in prepare_write, and skips redundant writes — matching LGHUB exactly. Same fix may apply to other Centurion boolean features whose firmware rejects no-op writes, but leaving those unchanged until observed. |

Solaar
Solaar is a Linux manager for many Logitech keyboards, mice, and other devices that connect wirelessly to a Unifying, Bolt, Lightspeed or Nano receiver as well as many Logitech devices that connect via a USB cable or Bluetooth. Solaar is not a device driver and responds only to special messages from devices that are otherwise ignored by the Linux input system.
