So in anticipation of procuring all the necessary bits, and peaces along with the “knowledge” 
, I’ve decided on my first “real” project. (once I’ve practiced enough)
What do you guys think? Is this possible and am I missing anything? Am I crazy… :-\
Motor Controller (Attic Fan)
Hardware Requirements:
I/O
- 2 Inputs (Solar and backup 12vdc)
- 1 Output (~12vdc) to motor
- Turn System Off/On (Hardware/Software Switch)
- Transmit power state (Solar or Backup)
- Transmit voltage level
- Transmit Temp and Humidity (although I guess I could build this out separately)
Firmware Programming:
- Automatically switch from solar to backup and vise-vera when solar power drops to a predetermined level.
- Automatically shut down at temp/humidity set point (I guess this could be unloaded to Vera)
Vera Programming:
Not even sure this is possible, The ability to:
- Turn system Off/On
- Receive power state (solar or backup)
- Receive voltage Level.
- Receive Temp/Humidity Levels
