The Smart Home Project by Perenio is a packaged solution for managing and securing your home,
apartment, store or office that is easy to be operated via a mobile application.
The system allows you to remotely monitor premises, as well as receive alerts and notifications and
timely react thereon, including the possibility to select predefined scenarios, view the history of events
and video records stored in the Cloud.

This project is based on IoT concepts. Application allows user to connect, monitor and control different
devices, such as gateway (master hub), sensors, power plugs, etc (product line still expanding).
Application was refactored on legacy code based on RIBs architecture (https://github.com/uber/RIBs).
All new code is covered with unit tests. Application receives data via both REST (initial data sync and
user actions output) and WebSockets (devices data update inputs). Data locally stored in Realm DB and
observed using RxRealm. All heavy data lifting is moved to separate dedicated background threads
(network input parsing, local DB worker, etc). All UI is code only based on PinLayout. All animations
and screen transition animations implemented using native frameworks. Statistics graphs implemented
using Charts with heavy customization by overloading its renderers.
