IoT Hotel Access Control System for Hospitality Operations

Executive Summary

Envative developed a scalable hospitality IoT platform for Armadillo Hotels Group using AWS IoT Core and cloud-based infrastructure. The system enabled mobile keyless room access, kiosk check-in, housekeeping automation, centralized monitoring, and multi-property operational management.

Hospitality Technology Challenges

Hotels Often Operate on Disconnected Systems

Hotels frequently rely on separate systems for:

• reservations
• housekeeping
• maintenance
• billing
• guest access
• employee permissions

This creates operational inefficiencies, data silos, and inconsistent guest experiences.

Traditional Hotel Keycards Create Operational Friction

Physical keycards introduce:

• front desk dependency
• lost card issues
• security concerns
• manual provisioning overhead

Hotel Operators Need Scalable Access Control

Modern hospitality brands require:

• centralized permissions
• mobile access
• employee role controls
• audit logging
• remote monitoring

The Client

Armadillo Hotels Group was formed with the idea of creating a different type of Hotel chain. One that would better support needs for company bookings and billing for multiple rooms, long-term stays, at an affordable price.

Hotel IoT System Architecture

Core Components

AWS IoT Core

Envative used AWS IoT Core to provision and manage hotel room devices securely at scale.

Mobile Keyless Entry

Guests could unlock rooms through a mobile application without requiring a physical keycard.

Asynchronous Messaging Layer

A message broker architecture enabled secure communication between:

• room devices
• cloud services
• mobile applications
• operational dashboards

Monitoring & Device Health Checks

The system continuously monitored:

• connectivity status
• hardware health
• device reliability
• access activity logs

Key Features

Challenge

As an outsider, a hotel’s operation appears to be simple—it sells lodging along with food and beverages. But a hotel is a highly complex operation where many departments must function, coordinate and interact together to ensure smooth day-to-day operations.

Armadillo’s vision for a comprehensive, secure, robust, and flexible hotel management software that could streamline operations across all hotel core service areas:

• front office
• housekeeping
• food and beverage
• accounting
• human services
• engineering and maintenance
• sales and marketing

The systems required to support all these functions create a high degree of complexity and integration. This is why, in almost every instance, hotels operate with multiple, disparate systems that do not “talk” to each other, which leads to inefficiencies, errors, customer dissatisfaction and reduced profitability.

This case study focuses specifically on the autonomous room access feature that AHG wanted to provide to its guests. In essence, Envative was tasked with implementing an IOT-enabled mobile, keyless room entry that  would allow guests to enter their room without having to first check in at the front desk and obtain a keycard.

Hospitality IoT Platform Architecture

This was a 12-month development project that started with Envative’s time-tested prototyping
phase to ensure that the team understood the features and functionality Armadillo wanted and make sure their expectations would be met. Envative’s web, mobile and IoT development teams all came together to map out the appropriate architecture for scalability and extensibility of Armadillo’s vision.

The teams planned their software delivery phases to include Minimum Viable Product features that could be launched first and then quickly followed by additional functionality in phases. While the teams took a “divide and conquer” approach to the massive project, they didn’t work in a vacuum.

Envative’s strength in technical project management, communication and additional prototyping ensured the teams worked cohesively toward the end goal. In addition, the company’s agile development process allowed each team member to respond to and incorporate feature-scope change requests along the way.AHG's goal was to provide autonomous, secure room and/or common area access for guests as well as employees such as housekeeping and maintenance staff. The access control solution needed to include monitoring, user permission control, reporting and logging of access activities.

AHG wanted to ensure user access would be reliable with safeguards in place to address potential connectivity issues.

In addition, they wanted to make sure the end result would be scalable and cost-effective so that they would could continue to offer their rooms at reasonable rates.

To support these features, Envative selected AWS IoT Core to provision devices for rooms and common areas and used Message Broker to send/receive updates to/from the devices in an asynchronous, secure, and reliable manner. Some of the IoT-enabled support features include:

• Support of housekeeping activities, allowing staff to enter the room when cleaning is required. The application reports back to management on all cleaning activities performed as well as other upkeep and maintenance needs of the room.
• In addition to securing individual room doors, the devices control common areas for guests or employees.
• Monitoring the devices in case of hardware or connectivity issues with a relay of health check information back to AWS.
• Custom CloudWatch metrics and dashboards were developed to monitor the overall health of thousands of devices.
• Access logs are recorded with each entry and stored in AWS DynamoDB
• Access logs include a camera snapshot of the entry attempt, stored in AWS S3.

Why AWS IoT Core?

Envative selected AWS IoT Core to provide the scalability, reliability, and secure device communication required for a modern hospitality IoT platform. The system needed to support real-time interactions between hotel room devices, mobile applications, kiosks, operational dashboards, and cloud infrastructure across multiple properties.

Secure Device Communication

AWS IoT Core enabled secure communication between connected hotel devices and cloud services using authenticated, encrypted messaging. This allowed guest room access systems, kiosks, and operational tools to exchange data reliably while maintaining strong security controls.

Scalable Multi-Property Infrastructure

The platform was designed to support future growth across multiple hotel properties. AWS IoT Core provided a scalable architecture capable of managing increasing numbers of connected devices, users, rooms, and operational workflows without requiring major infrastructure changes.

Real-Time Operational Visibility

The cloud-based architecture enabled centralized monitoring of:

• device connectivity
• room access activity
• operational status
• system health
• communication reliability

This improved visibility for hotel administrators and helped operational teams identify issues more quickly.

Asynchronous Messaging Architecture

Using asynchronous messaging patterns allowed connected systems to communicate efficiently without relying on tightly coupled real-time dependencies. This improved:

• platform reliability
• operational resilience
• scalability
• device coordination
• performance during peak usage

Device Monitoring and Health Checks

AWS services supported ongoing monitoring of IoT devices throughout the hospitality environment. Operational teams could track:

• online/offline status
• communication failures
• device reliability
• access events
• system alerts

This reduced operational blind spots and improved maintenance workflows.

Cloud-Native Hospitality Platform

The platform leveraged cloud-native infrastructure to simplify deployment, centralized management, and future feature expansion. This architecture supported long-term operational flexibility while reducing the complexity of managing distributed hotel systems.

Why It Mattered

For hospitality operations, reliability and usability are critical. Guests expect seamless room access and fast check-in experiences, while hotel staff require dependable operational systems behind the scenes. AWS IoT Core helped provide the secure, scalable foundation necessary to support both guest-facing experiences and internal hotel operations within a unified platform.

Operational and Guest Experience Outcomes

Improved Guest Experience

Guests could bypass the front desk and access rooms directly through mobile authentication.

Reduced Operational Complexity

The centralized platform reduced reliance on disconnected hospitality systems.

Scalable Hospitality Infrastructure

The system was designed to support additional hotel properties and white-label licensing opportunities.

Enhanced Operational Visibility

Management gained centralized monitoring and reporting across rooms and common areas.
