Next-Generation Integrated Smart Thermostat & Weather Station
Note
TL;DR - Amarula Solutions presents a unified Smart Thermostat and Weather Station powered by STM32MP2, Yocto Scarthgap, and Flutter — with onboard temperature, humidity, and pressure sensors, CAN Bus connectivity, and cloud integration via OpenWeatherMap. - Demonstrates full-stack capability: custom PCB design, 3D enclosure modeling, Linux BSP development, and Flutter GUI — all presented at Embedded World 2026.
Amarula Solutions is proud to present our latest innovation: a fully integrated, all-in-one Smart Thermostat and Weather Station. Evolving from our previous multi-board prototypes, this new showcase demonstrates our comprehensive ability to design, build, and deploy complete embedded solutions from the bare metal to the final user interface.
By consolidating powerful processing and environmental sensing into a single, beautifully designed custom hardware enclosure, we are pushing the boundaries of what is possible with modern Graphical User Interfaces (GUIs) on STMicroelectronics platforms.
How did we evolve from a multi-board prototype to a unified design?
- Our previous iteration utilized separate boards to handle Linux-based UI tasks and RTOS-based sensor readings.
Our new design brings everything under one roof.
Housed in a custom-designed, light blue mechanical enclosure with an integrated stand, the new system features a bespoke PCB designed entirely in-house. Key hardware highlights include:
Centralized Processing: Powered by the STM32MP2 microprocessor, handling complex tasks and fluid graphics effortlessly.
Onboard Environmental Sensing: We have directly integrated sensors onto two small PCB—clearly mapped for Temperature & Humidity, and Pressure.
Robust Connectivity: An onboard CAN Bus interface ensures the thermostat can seamlessly communicate with broader industrial or smart home networks.
How does the software stack enable smart functionality?
Running on a robust Linux Board Support Package (BSP) built with the latest Yocto LTS release (Scarthgap), the device boasts a stunning, highly responsive GUI powered by Flutter.
Real-Time Environment Control: The system reads onboard sensor data instantly, designed to trigger dynamic adjustments for heating, cooling, or ventilation.
Cloud Integration: The Flutter application seamlessly integrates real-time local weather forecasts using the OpenWeatherMap API, giving users a complete picture of both indoor and outdoor climates.
What is our end-to-end expertise?
This unified design exemplifies Amarula Solutions’ capability to act as a full-stack partner for custom embedded products. Our expertise spans:
Hardware & Mechanical Design: Custom PCB layout, sensor integration, and 3D enclosure modeling.
Operating Systems Development: Building highly tailored, secure, and optimized Yocto Linux images.
User Interface Design: Crafting modern, fluid, and intuitive applications using Flutter.
Open Source Contribution: Upstreaming patches for the Linux Kernel and Yocto project to ensure long-term stability and community support.
