Home & Building AutomationScenario

Whole-Home Smart Living

Touch panel and offline gateway

A home automation setup built around one Home Assistant hub per house. It brings voice and touch terminals, room sensors for climate, presence and energy, and security sensors into one place, and the automation rules run on the local hub. It suits homeowners, apartment and villa projects, and integrators who want one local system instead of a stack of separate apps.

Results reported by the design's authors on their own test setups. Yours depend on the site, so we confirm them in a pilot.

The problem

Why it matters.

Smart speakers cannot tell family members apart and send audio and faces to the cloud, timers waste energy in empty rooms, and mixed radio protocols and false-alarm sensors keep the home fragmented.

The flow

From signal to action.

01SenseRoom sensorsPresence radars, climate sensors, door contacts, leak probes and CT clamps report what is happening in each room.
02PeopleVoice and touchFamily members speak or tap on a terminal, which can recognise enrolled faces on the device itself.
03DecideHome hubHome Assistant runs every automation rule locally and decides what to switch.
04ActLights and ACRelays, curtains, lights and HVAC respond to commands from the hub over the home network.
05ConnectOptional cloudOnly wake-word conversation goes out to the online Xiaozhi service, and camera video stays on the LAN.

How it works

Step by step.

01Connect Home Assistant Green to the router over Ethernet and plug in a Connect radio stick for Zigbee or Thread devices.
02Fit sensors room by room: climate sensors on walls, contacts on doors and windows, leak probes near sinks and the geyser, CT clamps on breaker wires.
03Add a voice or touch terminal and enrol family faces by voice, up to 20 people.
04Set automations so presence and room conditions switch the AC and lights.
05Add an AI camera if you want person alerts that ignore pets and light changes. Only the event flag reaches the hub.
06Check the dashboard for room conditions and circuit-level energy use.

Before you install

A free Ethernet port on the home router for the hub, plus Wi-Fi in every room with a terminal.
Internet access if you want wake-word conversation, since that part uses an online service.
Access to the distribution board for CT clamps, fitted by a qualified electrician.
Wall space for climate sensors and a spot near each sink or geyser for leak probes.
For existing CCTV, RTSP streams and a processing host such as Jetson Orin, RK3588 or Hailo-8.

Good to know

Wake-word conversation needs the internet. Fully offline chat needs a separate package on an RK3588 with RK1828 or a Jetson Orin NX 16GB.
The hub has no built-in radio, so Zigbee, Thread or Z-Wave devices need a Connect stick.
HVAC control is designed for central AC controllers that speak OPC UA, Modbus or BACnet/IP, not wall-mounted split units, and it starts in observe-only mode.
Privacy points such as no face data leaving the home are design claims, not audited results.

How we deliver it

Paper to site, one team.

01Site surveyWe walk the site, or review photos and drawings, and agree what to measure and where each device goes.
02PilotOne lane, one line or one room first. We tune it on your conditions and agree what good looks like.
03Roll outWe supply the hardware in India with GST invoices, install it, and connect it to the systems you already run.
04SupportSpares, remote checks and model updates, with one team to call when something changes.

Questions

Asked before buying.

Does it work without internet?

Lights, climate, energy and security automations run on the local hub. Wake-word conversation needs internet unless you add the offline voice package.

Can it control our split ACs?

The HVAC design targets central AC controllers using Modbus, BACnet/IP or OPC UA. Split units are not the target, so check your model with us first.

Do we need rewiring for energy metering?

No. Split-core CT clamps clip around existing breaker wires. An electrician should still fit them.
