I'm slowly taking my first steps with Python in the meanwhile too. Unfortunately googling my way around this I wasn't able to find a block of code for a pH/TDS controller that I could just patch on Mycodo. It should be pretty straightforward -- take a pH+TDS reading every X minutes, (chart + display it online, like any fancy IoT toy,) and have a if-then function that activates peristaltic pumps connected to bottles with either acid, base, or nutrient solutions. (Of course the pH/TDS range needs to be adjusted differently during different phases of the plant life.)hideouspenguinboy wrote: ↑Sun Nov 26, 2017 6:35 pmAs for adding new pH/TDS, I bet he would consider some help to add those features. OpenSource community stuff and all. I can't imagine it would be super hard to import code from other people open projects using it.
Kyle, the guy behind Mycodo, looks like a fantastic guy, and I imagine he'd also enjoy tinkering with light emitting diodes as well. I just can't gather sufficient chutzpah to write him "you've got a great project going, why don't you dedicate your time to add a feature that I'd like." I guess that's a personality defect?

@mrNLK: Raspberry Pi is a little computer. Turning on and off light switches using relays commanded by a program is a pretty simple function it can definitely help with. If all you want is to control the lights on a central timer, why not simply get a mechanical timer switch to control the power going to all fixtures? https://www.amazon.ca/Kuman-24-Hour-Dig ... 01G5C9RC8/ (or other variants, of course, to handle the electric load.)
