2.0.0

A major release mostly dedicated to code restructuring and usability updates.

Features:

• #32: a better web interface, now also showing current bulb status with an icon and buttons for on/off. It should now also render correctly on mobile devices. Note that the direct flip URL has changed from /flip to /?flip; new actions /?on, /?off are now possible;
• #7: support for timer actions /timers (on/off/toggle) based on absolute time ("fire at 6pm"), time intervals ("fire every hour") or solar events ("fire at sunset + 10 min"). This feature requires definition of user time zone and location. A working Internet connection is required to synchronize time. A new dependency, Dusk2Dawn is required to calculate solar events;
• #15: bulb actions are now logged, and an online log browser /log is available;
• #19: ports to NodeMCU and ESP-01S boards (a port means the program will work out of the box by choosing the right settings in Arduino IDE);
• #32: all bulb manipulations (button, web, timers) now use LED in the same way to signal the action;
• #30: the way to enter Wi-Fi configuration has changed from holding the button on boot to holding it 5 sec anytime during the operation. Connection to a temporary Wi-Fi network now requires a password (see README for more info);
• #30: a new /about web page showing various information about controller;
• #4: Yeelight interface is split into dedicated files YeelightDS.h / .cpp, ready to be used as a library in other programs;
• #18, #22: button and LED handling are now offloaded to dedicated external libraries (AceButton, JLed), which do it better;
• new sections in README covering screenshots, examples of scripting, a schematic for ESP-01S board, an example of standalone library use.

Internal features:

• most of the code rewritten from good old C to C++, and now also adheres closer to Arduino coding practices;
• #7, #23, #24, #30, #32, #18, #22: porting to ESP-DS-System library, which brings many new features. The library is included with the sketch in the /src folder;
• #25: one more iteration on a better use of PROGMEM;
• avoid defining the multicast address twice (needs some pre-processor mastery);
• porting to ESP8266 Core v3.

Bug fixes:

• #10: discovery process not properly shown in Firefox.

1.1.1

Features:

• #17: porting to ESP8266 Core 2.5

Bug fixes:

• #16: Hiding the SSID of the esp8266 once it has been setup

1.1.0

Features:

• #1: Support for multiple bulb switching

Bug fixes:

• #6: Switch unlinking is not remembered

1.0.0

Features:

• Use of local API, meaning nearly instantaneous light switching;
• Support for Yeelight devices discovery on the network;
• Visible user feedback using the ESP8266's built-in LED;
• Support for Wi-Fi network reconfiguration;
• Web interface with mDNS support to configure the switch;
• Support for turning the bulb on or off via web interface, including a direct URL for toggle;
• Storing of the user-selected light device in EEPROM (survives power off);
• No hardcoded or entered bulb IP addresses;
• Detailed diagnostics sent over serial interface.
