4 days	Add DB schema version checkpersistence	xengineering
	This version is only compatible with the schema version 0. No migrations are implemented. Thus the DB is only accessed if the schema version saved as user_version is as expected.
4 days	Add reading server domain name from SQLite3 DB	xengineering
	It is annoying to type the server domain name on every app start. This should be way more ergonomic. As a minimal first step reading from the database is implemented and tested with an externally injected database.
14 days	Make ConnectionPage a StatefulWidget	xengineering
	This allows to store the fully qualified domain name (FQDN) of the MQTT broker and display it if the user visits the page again. The old behaviour was that the text input field was empty.
2026-03-08	Implement server selection	xengineering
	This lets the user select the fully qualified domain name (FQDN) of the MQTT broker. The FQDN is not yet preserved after a manual disconnect.
2026-03-08	Switch completely to connection state machine	xengineering
	This makes use of the state machine in the UI and implements all states and transitions planned so far.
2026-03-08	Add manual disconnect	xengineering
	This allows going back to the connection page and to choose a different server. Furthermore it might be useful to force a new connection attempt while auto-reconnect might be in a delay state.
2026-03-07	Remove automatic initial connection	xengineering
	The user should provide the fully qualified domain name (FQDN) of the MQTT broker manually and then press connect to actually connect including automated re-connects. As a first step the initial connect is bound to the manual button in the bottom bar. To reduce the scope the disconnect button is labeled "(disabled)" to make clear this is not expected to work.
2026-03-07	Label button with '(dis)connect'	xengineering
	This does not yet work but the correct text based on the page is displayed. This is based on a state machine based implementation suitable to implement the state handling cleanly.
2026-03-07	Start by default on ConnectionPage	xengineering
	This prepares starting connection attempts on manual action only.
2026-03-07	Allow switching between pages	xengineering
	This prepares manually starting the connection after server name insertion.
2026-03-07	Make ConnectionStatus a SafeArea by default	xengineering
	This removes the need to write a SafeArea on each use of ConnectionStatus and replaces it by exactly one occurrence.
2026-03-07	Add class ConnectionPage	xengineering
	This is a second page to offer a form to set the Sia server name.
2026-03-06	Move MaterialApp up to class Sia	xengineering
	This makes sure there is only one class instance of MaterialApp.
2026-03-06	Rename to class DevicesPage	xengineering
	The old name class UI was not adding much information and is not well suited to be differentiated to upcoming other *Page classes.
2026-03-06	Add `class Sia` as top-level widget	xengineering
	This simplifies the main function and adheres more to Flutter conventions.
2026-01-17	Protect bottom bar with SafeArea	xengineering
	On Android the bottom bar with the connection state used to be hidden by the three Android navigation buttons.
2026-01-17	Indicate disconnected Sia server	xengineering
	There are now three instead of two status states: - "Connected" / MQTT connected, Sia server connected - "Connection issue" / MQTT connected, Sia server disconnected - "Disconnected" / all other cases (Sia server connection unknown)
2026-01-17	Add automatic reconnecting	xengineering
	This allows to use the app after a temporary disconnect between app and MQTT broker.
2026-01-17	Display MQTT connection status	xengineering
	The user otherwise cannot trust the state of the contacts because the app could just be disconnected from the broker.
2026-01-16	Move Scaffold up to UI class	xengineering
	That balances the scopes of UI and ContactList better and allows to add more Widgets on the UI level.
2026-01-15	Set contact states based on MQTT	xengineering
	This is already the minimal viable product (MVP) for this app.
2026-01-11	Add const MQTT connection options	xengineering

2026-01-11	Switch to Map address to state for contacts	xengineering
	This map should be empty in the future and updated based on the incoming MQTT messages. A list was not the correct data structure for that since it requires to iterate over the whole list to find the entry with a certain address. But this is required to update the state of an already known contact.
2026-01-11	Fix indentation	xengineering

2026-01-10	Re-introduce timer-based state toggling	xengineering
	This is now done with the refactored code organization and a strict UI / data split.
2026-01-10	Move state to data.dart	xengineering
	The UI should not store the application logic state.
2026-01-05	Split code into three Dart files	xengineering
	This follows recommendations [1] from the flutter documentation. [1]: https://docs.flutter.dev/app-architecture/concepts
2026-01-05	Rename to `UI`	xengineering

2026-01-03	Make one contact toggle with timer	xengineering
	This demonstrates that the state of the contacts in the UI can be changed at runtime.
2026-01-03	Make ContactList a StatefulWidget	xengineering
	This is required to change the contact states during runtime.
2026-01-03	Specify Dart types explicitly	xengineering
	This makes the code more readable.
2026-01-02	Rename to ContactList	xengineering
	The old name MainPage did not explain a lot.
2026-01-02	Implement dummy `Contacts` UI	xengineering
	This demonstrates how the UI should look like. The data is just for visualization and never changes. Functionality is added later.
2025-12-22	Create flutter project	xengineering
	This was done using the following command. flutter create \ --description "Sia app" \ --org "eu.xengineering" \ --project-name "sia_app" \ --platforms linux,android \ --empty \ .
