Hardware Compatibility Matrix¶
The MyHOME integration supports all official BTicino and Legrand OpenWebNet gateways communicating via TCP/IP sockets or USB/Serial interfaces.
Supported Gateways¶
| Gateway Model | Protocol Support | Max Command Workers | Inter-Frame Delay | UPnP Discovery | Notes |
|---|---|---|---|---|---|
| F454 | OpenWebNet / HMAC | 4 workers | 50 ms | ✅ Port 49153 | Full high-speed multi-session support |
| F455 | OpenWebNet / HMAC | 4 workers | 50 ms | ✅ Port 49153 | Basic gateway (single SCS bus) |
| F461 | OpenWebNet / HMAC | 4 workers | 50 ms | ❌ Manual | Compact DIN Ethernet Web Server |
| MH202 | OpenWebNet / HMAC | 2 workers | 100 ms | ✅ Port 49153 | Modern scenario programmer gateway |
| MH201 | OpenWebNet | 1 worker | 100 ms | ✅ Port 49153 | Second-generation scenario programmer |
| MyHomeServer1 | OpenWebNet / HMAC | 4 workers | 20 ms | ✅ SSDP | Cloud/local hybrid gateway |
| MH200N | OpenWebNet | 1 worker | 150 ms | ✅ SSDP | Second-generation scenario programmer |
| MH200 (Legacy) | OpenWebNet | 1 worker | 150 ms | ✅ SSDP | Strict single-session pacing; watchdog hardened |
| H4890 / AM4890 | OpenWebNet | 1 worker | 50 ms | ✅ SSDP | 3.5" Touch screen display IP gateway (Axolute / Livinglight) |
| F452 / F453AV | OpenWebNet | 1 worker | 150 ms | ✅ Port 49153 | Audio/video & web server gateway |
| HL4684 | OpenWebNet | 1 worker | 50 ms | ✅ SSDP | 10" Touch screen display IP gateway |
| Legrand 3578 | OpenWebNet (Serial) | 1 worker | 50 ms | ❌ Manual (Serial) | USB / Serial gateway & OpenZigBee interface |
Note
Gateways with only 1 concurrent command session (such as the MH200N, MH200, or MH201) are automatically tuned with command pacing (100–150 ms) to avoid queue flooding. Modern multi-session gateways (F454, F455, MyHomeServer1) use 20–50 ms pacing with worker pools (up to 4 workers).

Note
Sound System (WHO = 16) Wiring: The 2-wire SCS bus carries both digital commands (power, volume, input routing via OpenWebNet WHO 16) and modulated stereo audio simultaneously over the same 2-wire bus. External audio streamers connect their stereo analog line-out to an audio source interface (e.g. Legrand / BTicino L4561N, L4560, or 3482), which modulates the audio onto the 2-wire SCS bus into the F441/F441M matrix inputs S1–S4. For full details and the official wiring schematic, see the Sound System / Media Player Guide.
Gateway Startup Discovery Capabilities¶
During startup initial discovery, status queries are gated strictly by gateway profile capabilities to avoid transmitting unsupported commands:
