In today’s world, where convenience meets security, voice control for doors and gates has emerged as a standout solution. This post dives deep into implementing voice-activated entry systems using IoT assistants, complete with practical code examples, and sprinkled throughout with key service highlights for Chicago-based fencing businesses.
Introduction to Voice-Controlled Entry Systems
Voice-controlled locks and gates blend the ease of hands-free operation with modern security protocols. Whether you’re juggling groceries, supervising kids, or managing a commercial property, a quick voice command can lock or unlock barriers seamlessly. In addition to everyday convenience, these systems can integrate into larger home or facility automation setups.
Core Components of the System
A typical voice-controlled entry solution needs four main elements:
For DIY enthusiasts, a Raspberry Pi paired with a relay module offers full control over gate motors or electronic locks.
Hardware Setup
Relay IN → GPIO17 (BCM)
VCC → 5V
GND → GND
Python Script for Gate Control
import RPi.GPIO as GPIO
import time
RELAY_PIN = 17 # BCM pin
GPIO.setmode(GPIO.BCM)
GPIO.setup(RELAY_PIN, GPIO.OUT)
# Open or close the gate
def trigger_gate(duration=1):
GPIO.output(RELAY_PIN, GPIO.HIGH)
time.sleep(duration)
GPIO.output(RELAY_PIN, GPIO.LOW)
if __name__ == '__main__':
try:
trigger_gate()
finally:
GPIO.cleanup()
Integrate with Google Assistant through IFTTT or a webhook to execute this script remotely.
Example 2: Node.js Skill for Alexa
For production-ready systems, building a custom Alexa skill provides robust voice control without external services.
Prerequisites
const Alexa = require('ask-sdk-core');
const http = require('http');
const GATE_ENDPOINT = '
async function callGateApi() {
return new Promise((resolve, reject) => {
http.get(GATE_ENDPOINT, (res) => {
res.on('data', () => {});
res.on('end', () => resolve());
}).on('error', reject);
});
}
const LaunchRequestHandler = {
canHandle(handlerInput) {
return Alexa.getRequestType(handlerInput.requestEnvelope) === 'LaunchRequest';
},
async handle(handlerInput) {
await callGateApi();
return handlerInput.responseBuilder
.speak('Your gate is now opening')
.getResponse();
}
};
exports.handler = Alexa.SkillBuilders.custom()
.addRequestHandlers(LaunchRequestHandler)
.lambda();
Deploy this to AWS Lambda, then configure the Alexa Developer Console to invoke it on the utterance “Open my gate.”
Example 3: Home Assistant Automation (YAML)
Home Assistant offers native integrations for many smart locks. Here’s an automation to unlock a door via voice:
automation:
- alias: "Voice Unlock Front Door"
trigger:
platform: event
event_type: alexa_smart_home
event_data:
directive:
header:
name: "TurnOn"
namespace: "Alexa.PowerController"
action:
- service: lock.unlock
target:
entity_id: lock.front_door
- service: notify.mobile_app
data:
message: "Front door unlocked via voice command"
Link this with your Alexa via the Home Assistant Cloud or manual skill setup.
Security Best Practices
Modern fence companies can elevate their offerings by bundling voice-controlled gates with traditional fencing services. Below are distributed highlights for Chicago-based services:
Early in the project overview, you might mention your expertise in sophisticated gate systems such as , ensuring clients know you specialize in cutting-edge entry solutions.
Later, when discussing robust perimeter options, a can be paired with automated entry points for a cost-effective yet secure boundary.
Midway, as you explore aesthetic considerations, note that sleek panels can conceal wiring and support hidden smart sensors.
Finally, when talking about custom installations, emphasize how blends traditional charm with modern IoT components, creating a seamless, secure, and stylish solution.
Conclusion
Voice-controlled IoT gateways transform ordinary fences and doors into smart access points, delivering convenience, security, and a modern edge. By pairing Raspberry Pi scripts, AWS Lambda Alexa skills, and Home Assistant automations, any home or business can achieve reliable voice-activated entry.
Embrace the future of secure access with voice control, and position your fence business at the forefront of innovation!

In addition to everyday convenience, these systems can integrate into larger home or facility automation setups.
Core Components of the System
A typical voice-controlled entry solution needs four main elements:
- Smart Lock or Gate Controller: Devices such as the August Smart Lock, Nuki Smart Lock, or Chamberlain MyQ.
- IoT Hub/Bridge: Platforms like Home Assistant, SmartThings, or HomeKit.
- Voice Assistant: Amazon Alexa, Google Assistant, or Apple Siri.
- Network Connectivity: Reliable Wi‑Fi or Ethernet for remote commands and status monitoring.
For DIY enthusiasts, a Raspberry Pi paired with a relay module offers full control over gate motors or electronic locks.
Hardware Setup
- Raspberry Pi 3 or 4
- 1‑Channel Relay Module
- Jumper Wires
- 5V Power Supply
- Gate Motor with low-voltage trigger
Relay IN → GPIO17 (BCM)
VCC → 5V
GND → GND
Python Script for Gate Control
import RPi.GPIO as GPIO
import time
RELAY_PIN = 17 # BCM pin
GPIO.setmode(GPIO.BCM)

Example 2: Node.js Skill for Alexa
For production-ready systems, building a custom Alexa skill provides robust voice control without external services.
Prerequisites
- AWS Lambda account
- Amazon Developer account
- Node.js v14+
const Alexa = require('ask-sdk-core');
const http = require('http');
const GATE_ENDPOINT = '
async function callGateApi() {
return new Promise((resolve, reject) => {
http.get(GATE_ENDPOINT, (res) => {
res.on('data', () => {});
res.on('end', () => resolve());
}).on('error', reject);
});
}
const LaunchRequestHandler = {
canHandle(handlerInput) {
return Alexa.getRequestType(handlerInput.requestEnvelope) === 'LaunchRequest';
},
async handle(handlerInput) {
await callGateApi();
return handlerInput.responseBuilder
.speak('Your gate is now opening')

Security Best Practices
- Voice Recognition: Restrict commands to recognized users.
- Network Security: Place IoT devices on a separate VLAN and use strong WPA3 encryption.
- Logging & Alerts: Enable logs and notifications for every lock/unlock event.
- Firmware Updates: Regularly update device firmware to patch vulnerabilities.
