First of all, thanks for this awesome project.

Since I'm debating whether to purchase an AWHP like this, I'd like to ask for some clarification:

• What's ONEWIRE / SDMETER / PENKTH000?
• I'm a bit uncertain about what can be read and controlled and what not, and the other issues have only deepened my confusion. Can the power consumption be set? Can the flow temperature be set?
• From what I understand, the setup is currently just for WiFi? I'd prefer cable based ethernet, but I guess that should be doable.

I'm very comfortable with helping to extend and possibly also clean up this project a bit from a software development point of view. Alas I am hopelessly untalented when it comes to electronics, so might need help there ;-)
