mmWave Presence

Fine-grained occupancy presence.

2 capabilitiesREST + secure WebSocketProduction schema

OVERVIEW

Built from capabilities, not assumptions.

mmWave Presence is a canonical HomeAutoPro sensors template. The same production capability schema drives validation, controls, reported state, telemetry, scenes and automations. Undeclared keys are rejected.

WRITABLE CAPABILITIES

Controls

This telemetry-first template has no writable controls.

DEVICE → HOMEAUTOPRO

Feedback / state

Every connected device also reports online state and last-seen time. Applied values remain distinct from requested values until the device acknowledges them.

Presencepresence

boolean. Read-only device feedback.

Distancedistance

number · cm. Read-only device feedback.

TIME-SERIES VALUES

Telemetry

Presencepresence

Validated boolean. Publish in a telemetry message.

Distancedistance

Validated number in cm, 0–1000. Publish in a telemetry message.

CAPABILITY-AWARE WORKFLOWS

Automations

Triggers

State/telemetry changes for presence, distance, plus online and offline events.

Actions

This read-only template cannot be an action target.

ACTUAL PRODUCTION PROTOCOL

Payloads and acknowledgement

Dashboard/API→HomeAutoPro→Device→Applied-state ACK

Authenticate

{"type":"auth","device_secret":"YOUR_DEVICE_SECRET"}

Telemetry

{
  "telemetry": {
    "distance": 500.0,
    "presence": true
  },
  "type": "telemetry"
}

CAPABILITY-GENERATED EXAMPLES

Sample code

Choose one platform. All examples use the production protocol and placeholders; no stored secret is retrieved.

#include <ESP8266WiFi.h>
#include <ArduinoJson.h>
#include <WebSocketsClient.h>

const char* DEVICE_CODE = "YOUR_DEVICE_ID";
const char* DEVICE_SECRET = "YOUR_DEVICE_SECRET";
WebSocketsClient socket;

// Handle only: (no writable keys)
// Connect: socket.beginSSL("api.homeautopro.in", 443, path);
// First message: {"type":"auth","device_secret":DEVICE_SECRET}
// After a command, publish {"type":"state","state":applied}.

#include <WiFi.h>
#include <ArduinoJson.h>
#include <WebSocketsClient.h>

const char* DEVICE_CODE = "YOUR_DEVICE_ID";
const char* DEVICE_SECRET = "YOUR_DEVICE_SECRET";
// Use TLS port 443 and the same authenticated command/state ACK lifecycle.
// Generate handlers only for: (no writable keys)

import requests

url = "https://homeautopro.in/api/device-ingest/DEVICE_CODE/telemetry"
headers = {"X-Device-Secret": "YOUR_DEVICE_SECRET"}
payload = {"telemetry": {"distance": 500.0, "presence": true}}
response = requests.post(url, headers=headers, json=payload, timeout=10)
response.raise_for_status()

const response = await fetch(
  "https://homeautopro.in/api/device-ingest/DEVICE_CODE/telemetry",
  { method: "POST", headers: { "X-Device-Secret": "YOUR_DEVICE_SECRET", "Content-Type": "application/json" },
    body: JSON.stringify({"telemetry": {"distance": 500.0, "presence": true}}) }
);
if (!response.ok) throw new Error(`HomeAutoPro ${response.status}`);

SAFE DIAGNOSTICS

Troubleshooting

401 authentication

Use the current Device Secret locally. Rotate it in Device Details if it was lost.

422 validation

Compare every key, type and range with the capability schema above.

No command ACK

Publish the value actually applied after handling event=command.
