Why this patch wasn't been upstreamed? Also would be good if "logitech-djreceiver" provides information for upower daemon as how did it happening with unifying receiver and my previous mouse Logitech Zone Touch Mouse T400. For example: $ upower --dump Device: /org/freedesktop/UPower/devices/mouse_hidpp_battery_0 native-path: hidpp_battery_0 model: Zone Touch Mouse T400 serial: 4026-cf-15-61-0d power supply: no updated: Sun 22 Dec 2019 02:41:30 PM +05 (89 seconds ago) has history: yes has statistics: yes mouse present: yes rechargeable: yes state: discharging warning-level: none battery-level: normal percentage: 55% (should be ignored) icon-name: 'battery-low-symbolic' Device: /org/freedesktop/UPower/devices/DisplayDevice power supply: no updated: Sun 22 Dec 2019 10:58:54 AM +05 (13445 seconds ago) has history: no has statistics: no unknown warning-level: none icon-name: 'battery-missing-symbolic' Daemon: daemon-version: 0.99.11 on-battery: no lid-is-closed: no lid-is-present: no critical-action: HybridSleep https://user-images.githubusercontent.com/200750/71320201-d8a5ea80-24c9-11ea-9ea9-97100545d294.png Currently, only sensors show the power charge level, but without "upower" daemon user-friendly indication not available in DE. $ sensors hidpp_battery_0-hid-3-9 Adapter: HID adapter in0: 4.08 V -- Best Regards, Mike Gavrilov.
