- WiFi Manager (captive portal with hotspot)
- MQTT Support (Subscribing and Publishing)
- WebSocket Support (Sending and Receiving)
- JSON Format Messaging (both MQTT and WS)
- SD Card Handling and File Ops
- Stand-alone Player/BellEngine Classes, with functions to Play/Pause/Stop etc
- NoteAssignments - Effectively mapping Notes to Bells
- Independent SubSystems for all Core Functions (Networking/Comms/Scheduling/Logging/etc)
- Custom Relay Output Maps and Timings (saved on SD)
- Timekeeper with RTC/Clock/Alerts/Scheduling features
- OTA Update Functionality with Versioning/Rollbacks/Checksum/Firmware Validation/NTP Sync
- Global logger with Mode Selection (None, Error, Warning, Info, Debug, Verbose)
- UDP Listener for Auto Device Discovery
- Datalogging and Statistics:
	- Counter for each bell (counts total times the bell ringed)
	- Counter per bell, beats/minute for reliability and thermal protection. Warranty Void scenario.
- Ability to change Log levels (in-app)



ToDo Features:

- (optional) Add Bluetooth support
- (optional) Add WiFi Direct AP Support
- (optional) Add PCB Temperature Sensor Support

- (critical) Counters and Statistics:
	- Counter per playback, to figure out which melody is the most played.
	  This can be implemented on the App itself. Doesn't need to be on the Device.

- Create a "humanizer" mode that randomizes delays on playback to simulate human ringing.


ToDo Fixes:

- (small significance) Fix each Log's level Correctly + Fix Log Syntax where needed
- (medium significance) BellGuard: Make the buttons functional. 

- Fix IP Settings not applying. More Specifically, Variables inside the Components take long to update. Either Ditch the components, or find another way.
- On Very fast playback speeds and small programs that will run for less than a second or so, STOP isn't sent properly. Player keeps indicating "playing".
- When a new user is created, set default PINs for both Quick Settings, and Settings.
