If you run a mini PC as a media server or HTPC in your homelab, you've probably been annoyed that it doesn't support HDMI-CEC — the protocol that lets your TV remote control connected devices. A write-up on XDA shows how a roughly $20 (£16-ish) USB-to-CEC adapter solves this neatly.

What's the trick?

The PulseEight USB-CEC adapter (sometimes sold under other names) sits between your mini PC's HDMI output and your TV. It adds full CEC support — meaning your TV remote can wake the PC, put it to sleep, control volume passback, and handle input switching automatically. The XDA piece focuses on turning a mini PC into a couch gaming rig, but the same setup works brilliantly for Jellyfin/Plex boxes or any headless-ish living room server.

Why homelabbers should care

If you've repurposed a Lenovo Tiny, Dell Micro, or any SFF box as an HTPC, CEC support removes the need for a separate keyboard or phone app just to wake the thing up. Combined with something like Kodi or Steam Big Picture, it makes the experience feel properly integrated rather than cobbled together. It's a small quality-of-life win that costs very little.

Caveats

CEC implementations vary wildly between TV brands — some are rock-solid, others are flaky. You may need to tinker with libcec settings on Linux, and Windows support can be hit-and-miss depending on your software stack. Also, the PulseEight adapter has been around for years, so this isn't new hardware — just an underappreciated one.

What to buy

Search for the PulseEight USB-CEC Adapter on Amazon. If you're running a headless mini PC setup and need a way to manage it without a display, our MS2131 HDMI Capture Card – 1080p Video & Audio for Headless Servers is worth a look too. And if your HTPC mini PC doubles as a NAS, a M.2 NVMe SSD Enclosure – USB-C 10Gbps with Magnetic Closure makes quick work of storage swaps.
