This is a simple on/off control for aquarium lights. I'm using the Electrodragon Wifi IoT Relay Board http://www.electrodragon.com/product/wifi-iot-relay-board-based-esp8266/.
It is currently running under V3.0 Alpha 8
It exercises timers, io pins, writing to files, use of time command (which still confuses me as DST does not seem to work as I would expect so I manually tweak it).

Here is my code so far. Basics work but sometimes it crashes, sometimes so bad it decides to delete default.bas so save often to notepad, etc.

Eventually I may set up a ramp timer for LED lighting. Made one using PIC but it's kind of nice to have a web interface and NTP for time!

Updated code quite a bit. Still has the crossing day boundary issue but not a problem for an aquarium light timer which is only supposed to be on during the day!

Fixed persisting the on/off times, time zone, DST and addressed my GUI issues. Not sure how to do anything but refresh the entire GUI. Any thoughts would appreciate it.

Here's the latest code which works and does not seem to crash. Still running under V3, Alpha 8.

Added a small tweak to highlight on the GUI if an update is made to times or timezone/DST and highlight an "ON" status for the relay.

This is great. Do you have any pictures of your aquarium or a video you might share? :-)
