edgehop

Push the mouse cursor against an outer edge of the screen, and your Logitech keyboard and mouse switch to another computer.

📖 Introduction

Logitech's Easy-Switch devices pair with up to three computers, but switching means pressing a button on every device. edgehop does it for you: when the cursor rests against a configured edge of the desktop, it tells each device to switch to another Easy-Switch channel.

• 🖥️ Works with one monitor showing both computers side by side (picture-by-picture, PBP) as well as with a separate monitor per computer. With PBP, the edge between the two halves is where you hop.
• 💻 Runs on Windows 10/11 (x64) and macOS on Apple Silicon.
• 🪶 Much lighter than Logitech's own Flow feature in Logi Options+:
  • 📦 A single static binary running as one small process: no installer or runtime.
  • 🔓 Runs without admin rights.
  • 🔌 Needs no network: the same binary runs on every computer with its own config. The computers never talk to each other; the devices carry the switch.

💿 Installation

Install edgehop with pixi:

pixi global install edgehop

See installation for starting edgehop at login and for other ways to install it.

⚙️ Configuration

Each computer has its own config.toml, describing its edges and devices. On the computer to the left, for example:

[edges]
right = 2 # switch to Easy-Switch channel 2 at the right edge

[[devices]]
name = "MX Keys S"
vendor_id = 0x046D
product_id = 0xB378
usage_page = 0xFF43
usage = 0x0202
device_index = 0xFF

Run edgehop --list to get the [[devices]] entries of your connected devices, ready to paste. See configuration for where the file goes and what each field means.

🎯 Usage

edgehop --watch        # switch whenever the cursor rests at a configured edge
edgehop --switch 1     # switch every configured device to channel 1 once, and exit
edgehop --list         # list the connected Logitech devices as config entries
edgehop --licenses     # print the licenses of the third-party software in edgehop

Add --verbose to log every step.
