Will do, likely over the weekend. I took a look at your home node; very interesting stuff!

The next phase of this project will be tying a bunch of things together into one cohesive application that will (for my indoor grow room):

• turn on/off a 120v exhaust fan when temperature goes above/below threshold (already done, RPi::DHT11::EnvControl)
• turn on/off a 120v humidifier if humidity goes above/below threshold (already done (same module as above))
• allow the temp/humidity limits to be modified (up/down) by pressing buttons
• open/close servos on my automatic drip systems on a schedule (or when a soil moisture sensor says so) for automatic plant feeding (have the hardware, just need to interface the servos with the Pi)
• display all of this information on the LCD (90% done)

Then, after I've got all that done, I am going to pick up a few different sized TFT displays, and write a GUI to wrap all this stuff, so on my wall, I have touch screen access to make adjustments and view statuses, instead of the LCD. This'll take me some time, because I haven't done any GUI programming in quite some time.

Thereafter, I'll buy/build a nice box for the whole shebang, put external connectors for the various sensors (instead of having them hard-wired), screw it to the wall outside of the grow area, and voila, I've created my very own complete indoor grow environment control centre :)

The only thing that won't be controlled by this device (at least not yet), are my HID lamps.
