Project goals

The goal is to provide a great application for smart home development and give a good overview of the most recent and old payloads on an MQTT broker.

The application should work with any backend MQTT broker.
No other backend services are necessary to execute this application.
The latest version of macOS, iOS, and iPad OS are supported. Older versions are only supported by using an older version of the application. This is necessary to reduce the development overhead in fixing and testing older versions.

No goals

Providing the best front end for controlling your smart home is not a goal. Every feature that will require extra backend services for push notifications is out of the scope of this application.
