Mina HC Gateway
Multi-protocol smart-home gateway: Zigbee 3.0, BLE Mesh, automations run locally without Internet.
The commercial Mina HC Gateway is being finalized. You can order a pilot unit (cased, tested, with direct support) or build the Early Bird edition from an ESP32-C6 board.
The Mina HC Gateway is the heart of the system — where IoT devices meet and automations run inside your home.
Device support (per build)
Zigbee build (v1)
- 5,000+ Zigbee models from Aqara, Tuya, IKEA Tradfri, Sonoff, Philips Hue, MOES, Lonsonho… (using zigbee2mqtt descriptors as the reference source)
BLE Mesh build (v1)
- Lights, switches, plugs that follow the SIG Mesh model spec
Future products (v2/v3)
- v2: Zigbee + BLE Mesh run simultaneously — no need to pick a build
- v3: adds RF 433 (PT2262 / EV1527 remotes, alarms), IR (A/C, TV), Modbus (power meters, inverters)

For developers — Early Bird (DIY)
Before the commercial edition, you can build a gateway from an ESP32-C6 SuperMini board (~$3 USD on AliExpress) and flash the Mina HC firmware right from your browser: /en/flash/. The sections below cover the Early Bird edition and the hardware roadmap.
Hardware roadmap
Mina HC ships in three generations, with growing radio + protocol capability:
| Version | SoC | Concurrent radios | Extra protocols | Status |
|---|---|---|---|---|
| v1 — Early Bird | ESP32-C6 | Wi-Fi + either Zigbee or BLE Mesh | — | ✅ Available now (DIY via /en/flash/) |
| v2 — Mina HC | ESP32-S3 + 802.15.4 NCP | Wi-Fi + Zigbee + BLE Mesh simultaneously | — | 🟡 In development |
| v3 — Mina HC Pro | v2 + add-on modules | + IR + RF 433 + Matter bridge | + broader integrations | 🔵 Roadmap |
The ESP32-C6 has a single 2.4GHz radio shared among Wi-Fi + 802.15.4 (Zigbee) + Bluetooth (BLE Mesh) — coexistence means all three can’t run simultaneously. Early Bird users pick one of two builds:
- Zigbee build — Wi-Fi + Zigbee 3.0 (P0 — first available)
- BLE Mesh build — Wi-Fi + BLE Mesh (P1)
Specifications — Early Bird (v1)
| Item | Spec |
|---|---|
| SoC | ESP32-C6 (single-core RISC-V 160MHz) |
| RAM / Flash | 320KB internal SRAM + 4MB flash |
| Wi-Fi | Wi-Fi 6 (802.11ax) 2.4GHz |
| Zigbee | Native Zigbee 3.0 (Zigbee build only) |
| Bluetooth | BLE 5.0 + BLE Mesh (BLE Mesh build only) |
| Power | USB-C 5V / 1A |
| Form factor | ESP32-C6 SuperMini (user-supplied board) |
ℹ️ Notes:
- The gateway can connect to Matter devices via Zigbee but is not Matter-certified
- IR / RF 433 / Modbus are exclusive to v3 with the add-on modules — Early Bird v1 doesn’t support them
Real-world capacity
Measured on an ESP32-C6 SuperMini with the full pipeline running (gateway + Wi-Fi + MQTT TLS + Zigbee):
- Free heap at runtime: ~130 KB (29% headroom after full init)
- Recommended scale: 25-30 devices + 8-10 automations + 5 scenes
- Local control latency: < 150ms from app to bulb (same Wi-Fi network)
- Target uptime: > 30 days continuous, with heap watchdog
