I have some bad news everybody.
From looking at the controller I have concluded that it uses the same hardware as my controller. However, IMHO, if I were to rewrite the code I would basically have to redo everything. Very little is developed, and much of it is not very efficient.
The features of the current controller are essentially a screen and temperature sensing. There also does seem to be a little light control, but I can't make it out.
IMHO, the people that bought the controller hardware would be better off either:
1. Creating a Jarduino. This will require a little more hardware, but it is by far the best controller out there.
2. Creating a different controller. Not sure about this one, but that Fernando Garcia one seems very good.
3. Creating my controller. No SD control, but the basic hardware is an Arduino Mega from ebay, DS18B20 temperature sensors, a DS1302 RTC, and a 3.2" 240x320 touchscreen.
What exactly did everybody buy?
