v4nelle:
congratulations for your perfect project!
Thank you very much! I did my best at the time, probably could do a better job programming it, but as you say it works so...Call me lazy

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.
When the sun is shining directly on it it's difficult to read the screen...

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.
It works stable, although you probably will need to buy better pH probes then the one's I've used. Also and this is an important one. Make sure the controller is shaded. High temperatures will mess up the stability of the device. Next year I will be installing it outside of the greenhouse in a waterproof housing and in the shade...
Have fun and if you got it working post some pictures here!!
