I could've uninstalled the package, but I moved it all to a separate VLAN until the warranty is over.

I'm debating writing a custom firmware, the GPIO pins are documented somewhere.

  * Run pump. 
  * Turn lights on / off / %. 
  * Measure water in tank. 
  * And then they have a moisture / temperature which they use for their 'AI' / heuristics on whether to water more or less. You don't need that. You just water more often. The point of hydroponics is that the roots sit in water. 
  * Occasional photo (via USB). 

I'm trying to find a Raspberry Pi Zero 2 W with the GPIO pins soldered on the 'other side', as that is how the Gardyn is setup.
