A letter from the developer Beta

I love my Logitech mouse.

I just wanted its battery percentage in my menu bar — without installing a 300 MB app that runs six background processes.

So I built something lighter.

The Solution

lsom talks directly to your mouse over USB or Bluetooth using Logitech's own HID++ protocol.

Battery percentage in the menu bar. That's what I wanted, so that's what it does.

What you get

DPI, polling rate, button remapping. The stuff you'd normally need G Hub for.

Free while it's in beta.

Get started

Install with Homebrew.

brew install --cask mikezamayias/lsom/lsom

Still rough around the edges. If something breaks, tell me.
