TimerClock_with_SunSet-SunRise

VERSION 3.1, Date: 18 November 2021

!!! Attention:

• Code written for ESP8266 (Core 2.7.4)
• Dusk2Dawn.h library download zip from Github! Don't install with Arduino IDE! (https://github.com/dmkishi/Dusk2Dawn)

Timer Clock program for the ESP8266. 4 timers with ON and OFF time or automatically switch ON and/or OFF by SunSet and/or SunRise with Offset. The timers control each a user definable GPIO and a http-command.

Hardware: ESP8266 (I have used the Wemos NodeMcu V3 Lolin).

My hardware design is described in document: "TimerClock Project (ESP8266) Schematic.xlsx" My Arduino IDE settings are in an screenshot called: "Arduino IDE setting.png"

Functionality:

• Webserver at http://ip-adres/
• Extended settings page where you can set Timezone, Longitude, Latitude and several GPIO controls
• Update your sketch bij http (settings page)
• Remote reset and restart (settings page)
• The program controls 4 outputs, which are in my hardware design connected to an RF remote control, which controls my ligths in my house (controls page)
• Every timer statuschange (ON or OFF) can also fire a http-command, you can use it for example for webhooks or Tasmota
• On the website you can control the outputs manually (in my case: switch the ligths on/off)
• On the website you can configure 4 timers (Timer a - d) (timers page) Every timer has it's own ON-time and OFF-time Per time you can choose if you set the time manually or set it to SunSet or SunRise (with up to 99 minutes offset)

Used Libraries:

• ESP8266WiFiMulti.h library to connect to WiFi and automaticly choose the strongest network
• ESP8266WebServer.h library to run the WebServer
• ESP8266HTTPUpdateServer.h library for updating sketch through http
• EEPROM.h library to write to, and read from EEPROM
• ezTime.h Very well documented Time libary with everything you possibly want! (https://github.com/ropg/ezTime)
• Dusk2Dawn.h Library to define Sunset and Sunrise (https://github.com/dmkishi/Dusk2Dawn)
• ESP8266HTTPClient.h Library to run as a HTTP cliënt (to send the http-commands)

Final Note, about me:

• I am not a programmer.
• I do a lot of trial and error, googling and look at other people's code. That's how i learn.
• I have tried to document the code as highly and clearly as possible.
• I am Dutch, so my English is not flawless...
• I really like to receive your comments or questions, thanks in advance.

GrTx, John
