LGS Tray Battery

A rewrite/combination of my two programs LGSTrayBattery and LGSTrayBattery_GHUB, which should allow for interaction via both the native HID and Logitech GaminG Hub websockets.

How to install

Please, visit the latest release page and download the release zip files from assets. Builds with the -standalone suffix are pre-bundled with .Net 8 and does not require any further dependencies, the non-standalone version requires .Net 8 to be pre-installed (https://dotnet.microsoft.com/en-us/download/dotnet/8.0).

Changes from V2

When migrating from earlier versions, device ids may have changed.

• Moved to .Net 8
• Realtime reactive icons and rich tooltips
  • Light/Dark theme is now reactive in realtime
• Rewritten to use hidapi directly for hotplug support
  • Wired/Wireless devices like the G403 should behave like a single device
• Multi-device mode
• Numerical Icons
• HID.NET manager has been deprecated
• Migrated to using a .toml for appsettings

Features

Tray Indicator

Battery percentage and voltage (if supported) in a tray tooltip with notification icon.

Right-click for more options.

Multiple Icons

Depending on the number of devices selected in the context menu, multiple devices can be seen simultatniously

Numerical Icons

Display the current battery percentage as a number.

In numerical display mode, charging status will not be displayed

Reactive Icons

Icon changes to match devices type (Current supported: mouse, keyboard and headsets)

Icon changes to match light/dark system theme

Icon changes to reflect current charging status

Http/Web "server" api

By default the running of the http server is enabled. The IP address and port used for bindings are under addr and port respectively with the defaults being localhost and 12321.

addr accepts either a hostname (DESKTOP-1234) or an IP address (127.0.0.1) to bind to, if you are not sure use localhost or if you have admin permission 0.0.0.0 to bind to all interfaces.

IPv6 can also be disabled with useIpv6 in the event that dual stack networking is causing issues.

If any issues arise from running the server, it can be turned off by the enable value in appsettings.toml under [HTTPServer].

Visit http://{addr}:{port}/ on your browser to view the list of devices available.

With the deviceID, a HTTP/GET request to {addr}:{port}/device/{deviceID}, will result in an xml document of the name and battery status of the device. Devices that do not support battery_voltage will report 0.00.

Device ids starting with dev originates from tapping into Logitech GHUB's own drivers, while random numbers are from the natively implement HID++ code. Thus, there are some fields that different between the two,

	GHUB*	Native
device_id	✔️	✔️
device_name	✔️	✔️
device_type	✔️	✔️
battery_percent	✔️	✔️
battery_voltage	❌	✔️**
mileage***	✔️	❌
charging	✔️	✔️

* - Requires Logitech G Hub Installed

** - Depends on the device

*** - Logitech G Hub's metric of estimated life left on the battery

HID++ Device Sources

As of v3.0.0, there are 2 sources in which the program will pull battery status,

• Logitech G Hub via Websockets
• Native HID, hidapi via PInvoke (Called "Native" in settings)

These sources can be individually disabled/enabled before runtime via appsettings.toml, in the their respective sections,

[GHub]
enabled = true

[Native]
enabled = true

GHub is Logitech G Hub, Native is hidapi

appsettings.toml

Refer to https://toml.io/en/ for a guide on toml syntax.

Note the " around strings

In the event of an invalid settings, at launch the app will prompt you for a reset to the default settings.

[Native] settings

• retryTime - The time in seconds to re-try a device on a failed device state query; usually the device is asleep.
• pollPeriod - The time in seconds to request an update from the device, keep this as high as possible as it may interfere with the default power saving sleep modes of devices.
• disabledDevices - If all else fails, and the addition of a new device has caused the app to be unusable. Adding a part of the device name into this list will prevent the device from being polled. E.g. The following will disable the G403 and G502,

disabledDevices = [
    "G403",
    "G502"
]

Known Issues

Common

• Native HID and GHUB do not provide similar percentages, this is due to how native and GHUB calculates percentages from the device's voltages. Native uses an average curve of a 3.7V lipo battery, while GHUB will use a lookup table specific to the device.

Native HID (hidapi)

• Certain wired devices like the G403 when in wired mode does not report the number of HID devices connected and will respond to all request. Causing battery polls to occur 6x per request.
• Device and protocol discovery changed from the previous method, some devices like the G533 headsets might not be detected, try the GHUB based manager.

GHUB

• Future GHUB version may change IPC protocol/endpoints (currently websocket)

Working with

• G403 Wireless
• MX Anywhere 2

Community Tested

HID Backend has changed, would need restesting of devices, please raise a PR to add to this list
