Billie's Hydroponic Controller

congratulations for your perfect project!
I want to make an automation to control the electrical windows of my greenhouse via sms
and i want to ask you if this touchscreen is readable on sunlight conditions.

Another question i have is : Do you think that this system will work stable on real conditions on a greenhouse?
My greenhouse is about 5000 m2 ,with high temps.

Sorry for my english 8)
