Live battery levels for Logitech wireless mice & keyboards. Charging indicator, low-battery alerts, fully local. Track battery levels of your Logitech wireless peripherals — mice, keyboards, presenters — across every Unifying, Bolt, Bicky, or Dagger receiver you own, right from the browser toolbar. ✦ Live battery percentage on the toolbar icon ✦ Charging indicator — the icon turns electric blue with a lightning bolt the moment you plug in ✦ Real-time updates — plug or unplug the charger and the icon reflects the change within seconds, thanks to the HID++ event subscription ✦ Low-battery desktop notifications with a configurable threshold and re-arm hysteresis ✦ Multi-receiver support — one extension, all your dongles ✦ Polished popup with per-device cards, animated charging bars, gradient theme ✦ 100% local — no telemetry, no accounts, no network requests HOW IT WORKS 1. Click the toolbar icon, then "Settings" 2. Click "Connect Receivers" and select your Logitech dongle(s) in the picker 3. Choose which devices to track 4. Set your low-battery alert threshold (default 20%) That's it. The extension talks to your receivers via the HID++ protocol over WebHID — the same protocol Logitech's own software uses — but stays entirely inside your browser, with no installer, no background service, and no data ever leaving your computer. SUPPORTED RECEIVERS ✦ Unifying (USB-A) ✦ Bolt (USB-A, USB-C) ✦ Logi Bicky ✦ Logi Dagger ✦ Any Logitech HID++ dongle in the same family REQUIREMENTS Chrome 117 or later (or recent Edge / Opera). WebHID is not available on Firefox or Safari. KNOWN INTERACTIONS If Logitech G HUB or Logi Options+ is running and holding the receiver, this extension will not be able to talk to it. Close the Logitech software (or quit its tray icon) before connecting. PRIVACY The extension does not collect, transmit, or share any data. It reads battery information from the specific receivers you authorize and stores your settings locally in Chrome's storage.
