AIR CONTROL APP

Client-Server solution for visualization and manage device`s data in real time.

The Embrox team has developed the device as well as its software that controls indoor air quality, temperature, and humidity.

This device will definitely become an essential part of the Smart Home. The users will be able to manage the device, customize it, and grant rights to other people.

Challenges

Implement the operation of the MQTT protocol with minimal support for a large number of devices.
Making use of cbor encoding for size reduction of messages in the MQTT protocol.
Instant management of device status.

Our Approach

The requirements have been analysed, the team with Java (Python) for the back, Angular for the front, developers and DevOps for configuring the infrastructure (MQTT broker, client, security of MQTT connection with devices, back and front) has been formed. PostgreSQL has been decided to be used as a database, because a productive database is needed in order to work with a large amount of data from devices.

What Our Team Says

Yaroslav

Backend Software Developer

One of the main objectives was to create the MQTT protocol, which operates with minimal delays with a large number of devices simultaneously. Finding the optimal solution was quite interesting. It was also a nice outsourced work on IoT, which made it possible to build clear communication and processes.
