Overview
A server shelf, a spare-room PC or a remote site is where this small plastic box works, capturing the HDMI output of a computer and sending keyboard and mouse back over USB. Ethernet carries the session, and Tailscale provides remote access.
Out-of-band access to a headless machine is the reason to buy it, since BIOS-level control works even when the operating system is down. No host software is needed. The limitation is that it manages a single computer and the listing says little about power and cabling.
Who it's for
Homelab hobbyists, small offices and remote-site admins who need to fix a machine without being there get the most from it. People who need a local multi-computer switch should buy a KVM switch instead.
Pros and cons
- BIOS-level remote control
- No host software needed
- Tailscale remote access
- Hardware video encoding
- Controls only one computer
- Power details not listed
- 4K limited to 30Hz
Performance notes
The device captures the video output and encodes it in hardware, then sends it to a remote browser or app over Ethernet. Because it acts as a keyboard and mouse over USB, it works before the operating system loads. Network speed and latency decide how responsive the remote session feels.

Frequently asked questions
Is the GL.iNet Comet GL-RM1 a KVM switch for several computers?
No. It has a single computer port and gives remote access to one machine over the internet, not a local switch.
Do I need software on the computer?
No. The highlight says no software is needed on the host computer.
Can it open the BIOS remotely?
Yes. The title and highlight both list BIOS control and BIOS-level access.
What is in the box?
The listing names only the GL-RM1 unit, so check whether cables and a power source are supplied.
