v1.1.7

Release Notes - Smart Aquarium V3.1

Version: v1.1.7 - 15-Day Periodic NTP Time Synchronization

---

Added

• New global variables for time tracking: timeNeedsUpdate and lastCheckedDay
• saveTimeUpdateTrackingToFS() function to persist tracking state to /time_tracking.json
• loadTimeUpdateTrackingFromFS() function to load tracking state on startup with defaults
• Setup logic to check RTC initialization and trigger NTP sync every 15 days
• RTC validation checking for year != 1970 and rtc.isrunning() state
• Error buffer messages for sync success, failure, and no-action scenarios
• Comprehensive debug logging in rtcTimeUpdater() with execution markers
• timeClient.begin() initialization before calling timeClient.update() - critical NTP fix
• 100ms delay after NTPClient initialization for UDP socket setup
• Early WiFi validation in rtcTimeUpdater() with status code logging
• Early RTC validation with proper error handling
• Epoch time validation (must be >= 1000000000 representing dates after 2001)
• NTP default server fallback to pool.ntp.org if empty

Fixed

• ArduinoJson compilation error: added #include <ArduinoJson.hpp> to resolve JsonDocument not in scope error
• NTPClient not initialized before update() call - now calls timeClient.begin() before timeClient.update()
• Missing 100ms delay for UDP socket initialization after begin()
• Insufficient error handling in rtcTimeUpdater() function
• Missing WiFi status validation before NTP operations
• Incomplete debug logging for NTP synchronization operations

HTML Changes

• Updated index.html to display Device status via /api/error endpoint
• Updated settings.html to display Device status via /api/error endpoint
• Updated specs.html to display Device status via /api/error endpoint

Breaking Changes

None. Feature is fully backward compatible.

How to Test

1. Monitor Serial output for rtcTimeUpdater debug markers
2. Check /api/error endpoint for status messages
3. Verify /time_tracking.json created in LittleFS
4. Confirm RTC time updated on first boot
5. Verify no sync attempts until 15 days elapse

v1.1.6

Fixed issues:
#9
#8
#7

v1.1.5

RGB LED Library change:

• FastLED to Adafruit NeoPixel over some issues.
• Added more insights using RGB LED
• Due to the Simple nature of RGB use, Adafruit saves 3KB in the BIN file and resolves some issues.

v1.1.4

• added buzzer and RGB LED for status and error reporting purposes (FastLED Library)
• added restart/reset button

v1.1.3

• Backup files will be named as aquariumBackupDDMMYYYY.json

v1.1.2

Changes:

1. Index.html: Added error polling function to fetch error messages from backend (if any, whenever occurs)

2. settings.html:

• Added danger symbol with tooltip for reboot required buttons
• NTP related settings will provided detailed info, now also requires reboot.
• Added error polling function to fetch error messages from backend (if any, whenever occurs)

3. specs.html: Added error polling function to fetch error messages from backend (if any, whenever occurs)

4. Main program:

• bumped program version to v1.1.2
• minor debug updates
• relays are by default disabled now (during fresh setup only)
• after NTP update, system will auto update rtc after reboot; new rtc update mechanism added
• new api endpoint /api/error added with error msg buffer for better error handling from frontend
• optimised rtcTimeUpdater( )
• overall better error management now

v1.1.1

Minor feature update:

• added specs.html page for real-time Hardware-related info
  Check the gallery section in the readme for details.

v1.1.0

Releasing v1.1.0 with massive updates.

• There is a Wi-Fi manager now. The device sets up the server at 192.168.4.1 on the first run. Go to settings and set up.

• Settings Page now has:

• Backup Button: Downloads all the configurations to your PC/Smartphone in a simple JSON file
• Restore Button: Restore the configuration/setting from the Downloaded Backup JSON file
• Both these buttons have a loading animation for a better User experience
• WiFi setting: Now set the WiFi SSID and Password directly
• Set Static IP
• NTP settings like timezone and NTP server

• A clock that shows RTC time (every 30 seconds refresh)

• Other bugs fixed

• Updates in some documentation areas

Check out the readme for details.

v1.0.1

• updated default ntp pool to India
• updated copyright symbol
• update LED to Relay in some places index.html
• updated readme about NTP
