Managing a remote server is easy until it isn’t, and a dead network connection or a failed boot sequence leaves you powerless. The GL.iNet Comet (GL-RM1) promises a lifeline, packing full KVM-over-IP functionality into a device no larger than a streaming stick. This tiny tool could fundamentally change how you manage your homelab or remote systems, democratizing a feature once reserved for expensive enterprise hardware.
The Comet’s design is its most immediate and impressive feature. It’s a compact, lightweight HDMI dongle that eschews the bulky, multi-component nature of DIY solutions like the PiKVM. Constructed from a simple matte black plastic, it won’t win any design awards, but its practicality is undeniable. On its small frame, it houses an HDMI input for video capture, a USB-C port for both power and keyboard/mouse emulation, an Ethernet port for network connectivity, and a header for ATX power/reset switch control. This self-contained approach is a massive win for anyone with limited space or a desire to avoid cable clutter.
In terms of performance, the Comet delivers exactly what a system administrator needs. The web interface, built on the robust and familiar OpenWrt platform, provides a clear, low-latency video stream of the target machine’s display at up to 1080p at 60Hz. While there is a perceptible delay that would make it unsuitable for gaming or fast-paced video editing, it is perfectly responsive for navigating a BIOS, troubleshooting a boot loader, or performing basic OS-level tasks. The true magic lies in its out-of-band capabilities. The ability to mount a remote ISO file as virtual media is a game-changer, allowing for complete OS installations from anywhere. Similarly, the ATX control lets you force-reboot a completely frozen machine, providing the ultimate remote “power button.”
Where the Comet truly shines is its value proposition. It elegantly bridges the gap between cobbling together a Raspberry Pi-based KVM—a project often fraught with component shortages and configuration headaches—and investing in expensive, proprietary enterprise solutions like Dell’s iDRAC or HP’s iLO. GL.iNet has packaged the core functionality of these systems into an accessible, affordable, and largely plug-and-play device. While the software may have a few minor quirks and the plastic build isn’t as rugged as its rack-mounted counterparts, these are minor trade-offs for the convenience and power it provides.
For the homelab enthusiast, small business admin, or developer who needs reliable, BIOS-level access to remote machines without the enterprise price tag, the GL.iNet Comet is an almost indispensable tool. It solves a critical problem with an elegant and cost-effective solution, turning potential crises into minor inconveniences handled from the comfort of your own desk. It’s not a perfect device, but it’s the perfect device for a very specific, and very common, set of challenges.
