Installation

Software requirements

• Operating system with support of periodic job scheduling (for example *nix with cron)

• Web server with PHP support, tested with Nginx (recommended), Apache and Litespeed

See also these hints for details!

Hardware requirements

• A server, which fits the software requirements :-)
  A Raspberry B with a 4 GB SD card works fine for me as scripts server connected to a central frontend/API sever.
• Some sensors, like 1-Wire sensors, watt meters with S0 or D0 outputs
• Solar inverter which supports either
  • live query of data (SMA Webbox, Fronius, Kaco, Kostal)
  • write data in short intervals (quasi-live) somewhere
