• Weppy was initially written in about 2-3 days. It was written to assist in a presentation on E+.
• Now it has become a useful tool to understand how E+ builds it's HVAC.
• This understanding is being used to further develop functions in eppy
• Apart from this, weppy is showing potential for being a good viewer for E+.
• You are welcome to fork it and build such a viewer.
  • the eppy team may be motivated to write functions that will assist you in this.
• Any comments or ideas for further development can be posted as an issue (or as a comment in an issue) in weppy

• clone weppy
• git clone https://github.com/santoshphilip/weppy.git into a folder of your choice
