Real-time communication from hardware triggers to screen content

The Three Pillars of IoT Signage

A complete ecosystem for connected digital signage

SignStudio

Your cloud-based command center. Design presentations, manage players, and configure IoT triggers from anywhere.

Visual content designer
Player fleet management
Schedule automation
Analytics dashboard

SignService

The local watchdog and API gateway. Receives IoT triggers and translates them into player commands.

REST API endpoint
GPIO monitoring
WebSocket support
Auto-recovery daemon

SignPlayer

The display engine. Renders content and responds to commands from SignService in real-time.

HTML5 rendering
Video playback
Scene switching
Multi-zone layouts

IoT Use Cases

Real-world applications powered by connected signage

🏷

Elevator Display

Automatically switch content based on floor level. Show relevant ads and information for each floor's audience.

GPIO Floor Sensor

🔥

Fire Alarm

Override all screens with emergency evacuation routes when fire alarm triggers. Safety first.

Alarm System API

🖐

Interactive Kiosk

Physical buttons trigger different content scenes. Let users browse products or services hands-on.

GPIO Buttons

🌡

Temperature Display

Show real-time temperature from sensors. Promote cold drinks when hot, warm coffee when cold.

I2C Temp Sensor

API Examples

Simple HTTP calls control your signage

switch-scene.sh

# Switch to emergency scene via curl
curl -X POST http://localhost:9999/api/v1/command \
  -H "Content-Type: application/json" \
  -d '{
    "command": "switchScene",
    "sceneName": "fire-evacuation",
    "duration": 0
  }'

gpio-trigger.py

import RPi.GPIO as GPIO
import requests

def on_button_press(channel):
    requests.post(
        "http://localhost:9999/api/v1/command",
        json={
            "command": "switchScene",
            "sceneName": "promo-display"
        }
    )

GPIO.add_event_detect(17, GPIO.RISING,
    callback=on_button_press)

temperature-monitor.js

// Node.js temperature-based content switching
const axios = require('axios');
const sensor = require('node-dht-sensor');

setInterval(async () => {
    const { temperature } = sensor.read(22, 4);

    const sceneName = temperature > 25
        ? 'cold-drinks-promo'
        : 'hot-coffee-promo';

    await axios.post('http://localhost:9999/api/v1/command', {
        command: 'switchScene',
        sceneName,
        transitionType: 'fade'
    });
}, 60000); // Check every minute
