Build your own access control system with ESP32.
CloudAccess is a DIY project for makers and hobbyists: an ESP32 controller, RFID cards, browser-based management and cloud monitoring — in a system you can test, understand and extend.
Technologies used in CloudAccess
A complete project for access-control experiments
CloudAccess combines ESP32 firmware with a web interface and cloud services. It is designed as a practical project for learning, prototyping and DIY access-control automation.
Browser control
Configure and control the project from your browser without staying permanently connected to the ESP32 board.
RFID access
Add cards and users and quickly decide who has access.
Flexible permissions
Organize users and access rules according to your space and needs.
Remote control
Trigger a door opening directly from the platform whenever needed.
Multiple locations
Manage different devices and access points from the same account.
Simple setup
Configure the controller locally, then connect it to CloudAccess for centralized management.
Real-time monitoring
Quickly see whether devices are online and follow the system status.
Event log
Keep visibility into access events and important actions.
Firmware updates
Maintain and update device firmware without complicated on-site steps.
CloudAccess in your browser and on Android
The web application at app.cloudaccess.ro is the CloudAccess administration center. From there you can configure devices, manage users and RFID cards, define access permissions, review events and activity logs, change system settings and remotely control connected devices.
The Android application is designed mainly for end users. It provides quick access to everyday functions such as remote opening and management of their own cards, without exposing the advanced administration options available in the web application.
The web and Android applications use the same CloudAccess account and the same data, so access rights, cards and changes made in the system stay synchronized.
Control access from anywhere, from one platform.
SECURITY
Secure communication between components
CloudAccess protects communication between apps, cloud services and the controller through secure connections and authentication mechanisms, without complicating everyday use.
HTTPS/WSS connections for communication with CloudAccess services
Token-based authentication and session control
OTA updates and controlled access to administration features
How to use it
From installing the controller to day-to-day management, the workflow is simple and easy to follow.
1. Prepare the controller
Flash the firmware to the ESP32, connect it to the network and configure the hardware for your prototype.
2. Add cards and users
Register RFID cards, create users and test access rules directly from the web interface.
3. Experiment from the cloud
Monitor the device, review events and test remote commands from CloudAccess.
