Meet reTerminal E, the Latest ePaper Display HMI for Your Smart Space
Meet reTerminal E, the Latest ePaper Display HMI for Your Smart Space
Back in April 2025, we released the original XIAO 7.5” ePaper Panel, which gained lots of attention. But we knew we could do even better. After months of development, we are proud to unveil our new series ePaper display—reTerminal E. Powered by the Espressif’s ESP32-S3, it‘s a Human Machine Interface coming with 2 ePaper display options of 7.5‘‘ monochrome display and a 7.3‘‘ full–color display, with up to 3-month battery life. And to top it off, we’re launching it together with our new AI-powered, no-code UI design and deployment platform Sensecraft HMI.
The reTerminal E comes with two models:reTerminal E1001 7.5” Monochrome ePaper Display and reTerminal E1002 7.3” Full-color Display. Both models are available at our official webstore Bazaar with limited quantities, priced at $79 and $109 respectively. And AliExpress Store is coming soon!
What is HMI
HMI (Human Machine Interface) is the interface that enables interaction between humans and machines/equipment. It serves as a control panel or dashboard that allows users to monitor, control, and manage systems or devices. HMIs typically include displays showing real-time data, system status, and controls for user input. Modern HMIs often feature creens, graphical interfaces, and can range from simple button panels to sophisticated interactive displays with data visualization and remote access capabilities. The key goals of HMI design are to provide intuitive operation, clear information display, and reliable system control while ensuring user safety and operational efficiency. The reTerminal E serves as a bridge between you and your smart space, offering an easy-to-use display that allows you to visualize everything with just a glance.
Powerful Hardware in a Ready-to-Use Device
The reTerminal E series boast a sleek, sophisticated design, featuring an elegant metal enclosure that enhances both durability and aesthetics. Here are some highlited hardware features:
- Powered by the ESP32-S3: Ensures enhanced image processing and smoother user interface rendering.
- Two displays options: Choose between a 7.5-inch monochrome and a 7.3-inch full-color ePaper display, both with 800×480 resolution for crisp text and images.
- Long battery life: 2000mAH rechargeable battery, which operates up to 3 months life on a single charge. And the battery status can be accessed on the scre
- Onboard resources designed for more use cases: To save users the trouble of external wiring, we’ve pre-equipped the device with frequently used modules like a temperature & humidity sensor, and a buzzer, making it easier than ever to build interactive and environment-aware applications.
- Enhanced interface interactions: Equipped with a microphone and three physical buttons, including a wake-up button and two page navigation button, providing a richer interaction experience for more effiecient development.
To enhance the best user experience while upgrading our hardware, we introduce a new software platform: Sensecraft HMI. This AI-powered dynamic display interface takes device UI design and deployment to the next level, delivering a smart and no code way to build interfaces for your ePaper dashbaords.
- No Code UI Design: A drag-and-drop canvas tool and a rich library of prebuild templates make UI design simple for everyone.
- AI Generation: Simply describe what you want, and the AI will generate stunning images that can be refined through multi-turn conversations.
- Various Data Source: It can display real-time data from onboard sensors and web APIs
- Quick UI Deployment: Easily prepare and deploy visuals to your ePaper display on a single platform with just a few clicks.
More Software Compability for Flexible Development
Rest assured, while Sensecraft HMI introduces powerful new features, reTerminal E remains highly open, flexible and developer-friendly. It is fully compatible with TRMNL, Home Assistant via ESPHome, and Arduino / PlatformIO ensuring a seamless experience across various development preferences:
- ESPHome Integration: With native ESPHome support, reTerminal E can be easily connected to your Home Assistant, allowing effortless visualization of your smart home data, and automation.
- TRMNL Compatibility: Access over 400+ plug-ins tailored for daily life and work, including Reddit, GitHub, calendars, and more.
- Arduino/PlatformIO Support: Enjoy professional development workflows in VS Code, with one-click build, upload, and serial monitoring, which is perfect for rapid prototyping.
Whether you’re a beginner or a seasoned developer, reTerminal E adapts to your preferred workflow, letting you design and manage your interfaces the way you like—from no-code tools to full-stack control.
