Smart Home IoT system with mobile app
Custom temperature and humidity sensors, connected over Bluetooth and WiFi, with a dedicated iOS/Android app that shows the data in real time, in charts and with history. A complete IoT system, from the board to the cloud.
The problem: a home in the dark
Without measuring, you don’t know what’s going on in each room: temperature, humidity, comfort…
Off-the-shelf products don’t fit
Generic solutions don’t adapt to your hardware or to how you want to see and store the data.
A single reading isn’t enough
Seeing the current temperature isn’t enough: you need history and charts to understand what’s happening at home.
How it works
Custom sensors all over the home and a dedicated app that brings it all together.
Custom sensors
Nodes with a custom PCB that measure temperature and humidity in every room.
Connected over BLE and WiFi
The sensors pair with the app over Bluetooth and upload data over WiFi.
Dedicated iOS / Android app
A custom app shows the status of each device and each room in real time.
Charts and history
Data is shown in charts and stored in a database so you can review the history.
What we built
A complete IoT system, from the sensor to the app, end to end.
Custom hardware
Own PCB with a temperature and humidity sensor and Bluetooth and WiFi connectivity.
Firmware and connectivity
Sensor reading, BLE pairing and data upload over WiFi.
Cross-platform app
Native iOS/Android app: user access, device and room management, and real-time visualization.
Backend and history
A database with each sensor’s history and trend charts.
