Zgemma H11s Review Top Access

Let’s look at the silicon that makes this device tick. The H11S is built on a HiSilicon Hi3798MV200 processor – a 64-bit ARM Cortex A53 chip clocked at 1.6GHz, paired with 1GB of DDR4 RAM and 8GB of eMMC flash.

The Verdict on Specs: 1GB RAM is the bare minimum for heavy Enigma 2 skins (like FHD skins). If you run only basic skins and plugins, it’s smooth. For heavy multitasking, consider the H11S 2GB variant.

Conclusion: H11S is the cheapest twin tuner Enigma 2 box. If you can spend €50 more, get Octagon SF8008 for 4K and better support.

To decide if this is the top choice, let us compare it directly to its rivals.

Conclusion: The Octagon SF8008 is technically superior (2GB RAM, FBC tuner), but it costs 40% more. The Zgemma H11S wins on value. If "top" means best performance-per-dollar, the H11S leads the pack. | Feature | Specification | | :--- |

CPU: Broadcom BCM7251S (dual-core 1.5 GHz) – same chipset as older Zgemma H9 series.
Performance: Smooth for SD/HD channels, EPG navigation, and basic plugins. Slightly sluggish on heavy skins or EPG data (e.g., Rytec XMLTV).

Tuner sensitivity: Good – locks channels quickly, even on weaker signals (tested with 80cm dish on 28.2°E, 19.2°E, 13°E). Blind scan works but slower than Vu+ or Edision.

Recording & playback:

Boot time: ~45 seconds from cold boot (OpenATV 7.3). Standby resume is instant. | Model | Price | Tuners | CPU

The H11S ships with a generic OpenATV 6.4 (or newer 7.x depending on stock). You must flash your own preferred image.

Best images for the H11S:

Wi-Fi & Networking: The H11S has no internal Wi-Fi. You must use a USB dongle (Realtek RTL8812AU works best) or simply use the Gigabit LAN port. I recommend wired – wireless dongles cause latency with 4K IPTV.

CEC Control: Works flawlessly with LG and Samsung TVs. The remote can control TV volume/power out of the box after HDMI-CEC setup in the menu.
