Hi,
I hope this message finds you in good health and spirits.
Like many other GeoSpring hybrid water heater buyers, I was very excited to get my water heater installed, only to find out later that control of the water heater seems less controllable than a regular water heater. I wanted to try GE's ConnectPlus, but they're not currently available and the reviews weren't very flattering. I'm of the idea that Green Bean is a more robust interface, but I can't find one to purchase. I was hoping someone here might know where to find a Green Bean interface to purchase, and if not, perhaps maybe your travels happened to come across a schematic or the ability to use an Arduino, Raspberry Pi or other device to directly monitor and control a GeoSpring water heater?
