SIMO.io Smart Home Network Architecture
SIMO.io introduces a game-changing professional smart home system architecture that is reliable, extremely comprehensive, yet super simple!
In a quiet room, control should feel like silk. A SIMO.io home begins that way: the hub on‑prem, a spine of Ethernet and PoE, neat panels on DIN rail. No spectacle. Just a system that moves when asked, holds when challenged, and keeps its posture when the street blinks. Wire‑first. Local‑first. Open source.
Why this backbone wins
One authority, at home. The SIMO.io hub runs your scenes, lighting, HVAC, and security on your LAN—even when the internet sulks. Under the calm: Intel N100 (4 cores, up to 3.40 GHz), 8 GB RAM, 256 GB SSD—and a 128 GB rescue USB that takes 12‑hour LVM snapshots with BorgBackup for ≈20‑minute bare‑metal recovery. Drama becomes a drill.
One cable, two gifts. Ethernet carries intent. PoE carries power. Put the router, hub, and PoE switch on a UPS and your control plane keeps breathing through outages. Quiet resilience; soft continuity.
Work happens at the edge. Each “logical center” is an electrical panel with The Game Changer board. Sixteen universal I/O on the main board; add the Extender for +22 I/O—38 at that panel without rewiring. Wire once. Snap in modules. Scale without rework.
The everyday muscle. Relays, dimmers, and binary inputs do the work. Our relay module carries dual MOV surge absorbers and a disposable fuse; dimmers mind isolation and ratings; inputs are opto‑isolated. Beauty at the surface. Discipline inside.
The room companion. Sentinel belongs in every room. Ceiling‑mounted, PoE by doctrine, with AI voice, true 3D presence, air awareness, lux sensing, and a 100 dB siren—reporting to your local SIMO.io hub. One per room is the right habit.
Local loops, graceful failover. After configuration, physical button → light closes inside the logical center. So even if the hub is unreachable, lighting remains immediate and predictable.
Let the others dance; here’s where they tire
Zigbee, Z‑Wave, Thread, Wi‑Fi (radio meshes)
Clever on slides; fragile in walls. Sleeping nodes, interference, jamming risk, and batteries with opinions. Re‑pairing after a hub swap eats weekends. Good for gadgets; not for a home’s spine. We use wireless sparingly—only where a wire truly cannot go.
Cloud‑hosted hubs (cloud‑first patterns)
Pretty apps, brittle reality. Outages, rate limits, forced updates, disappearing APIs. It’s a manager who’s never home. We keep authority at home; remote access and AI ride shotgun, not in the driver’s seat.
KNX (legacy fieldbus)
Respect to the elders, but by today’s IP standards it’s stone‑aged: slow links, specialized tools, costly expansions. We keep the discipline—and move the backbone to Ethernet/PoE, where the modern world already runs.
How the architecture unfolds, gently
1) The authority: your SIMO.io hub
It doesn’t ask permission from a cloud. It serves your home from the inside and keeps its promises under pressure. The rescue USB takes 12‑hour LVM snapshots with BorgBackup; bare‑metal recovery is typically ≈20 minutes. You feel the difference most when nothing “exciting” happens—because it just works.
2) The spine: copper that behaves
Ethernet is civilized wiring: deterministic timing, clean segmentation, and no batteries to placate. PoE turns that same run into a lifeline. One UPS under router + hub + PoE switch keeps the brainstem awake when mains blinks. Your home stays graceful.
3) The logical centers (Colonels in the app)
Open the panel: The Game Changer board on DIN rail. Sixteen universal I/O accept relays, dimmers, and inputs; two front‑line bays (IO1, IO2) host digital interfaces when a zone needs a bus. Need more I/O? Add the Extender (+22) and keep your plan. Change the module, not your weekend.
4) The room layer: Sentinel in every room
Panels do the heavy lifting. Sentinel finishes the experience: “Hey SIMO” voice that understands your scenes and devices; true 3D presence at room scale; temperature, humidity, VOC/air‑quality and lux; and a 100 dB siren for unmistakable alerts. Wire‑first by doctrine (PoE 802.3af with 10/100 Ethernet). With a local SIMO.io hub, control remains on‑prem; only AI understanding uses SIMO.io cloud.
A simple way to picture scale
Small apartment
One electrical panel serves as your logical center. Often one Game Changer main board plus Extender in the same cabinet with breakers and low‑voltage supplies. PoE home runs land here. Lights, valves, sensors—local and tidy.
Two‑floor apartment or townhouse
Two logical centers—one cabinet per floor, each with a Game Changer (add Extenders where density demands). Shorter cable runs, fewer junctions, faster service. One hub, one UPS triangle, many calm panels.
Large house or multi‑building property
Several logical centers distributed across floors and buildings. PoE (or fiber backhaul to PoE) ties them together. Each cabinet hosts one or more Game Changers (and Extenders). The LAN is one composed fabric; the work stays local to each area.
Everyday control, even if the hub naps
Physical buttons drive lights inside the panel. The loop closes at the logical center. Scenes and schedules live on‑prem—but the essential behavior, the click and the light, remains instant even if the hub is unreachable.
Buses exist; elegance remains
We support DALI for addressable lighting and I²C for tidy digital sensors. Useful, yes. But not the headline. The point is a calm IP‑first backbone with PoE, panels that do the work, and rooms that respond like silk.
For professionals, said softly
- Keep the control plane boring—segment it if you like. Land grounds cleanly. Respect SELV boundaries. Use licensed electricians for mains.
- Build repeatable panels. The SIMO.io app mirrors reality: logical centers appear as Colonels, so software follows the brass in the cabinet.
- Prefer CAT6, label both ends, and protect PoE distribution on the same UPS as the hub and router.
The feeling you leave with
Not a gadget pile. A composed system. The SIMO.io hub as quiet authority; a PoE backbone that doesn’t fuss; panels that act with precision; Sentinel in every room, attentive and gentle.
Wire once. Snap in modules. Scale without rework.
Local authority. Cloud only when it adds value. Professional by default.
