emonpi install

Please read the CT installation guide before installing. Your safety is your responsibility. Clip-on current sensors are non-invasive and should not have direct contact with the AC mains. However, installing the sensors will require working in close proximity to cables carrying high voltage. As a precaution, we recommend ensuring the cables are fully isolated; i.e., switch off the power prior to installing your sensors and proceed slowly with care. If you have any doubts, seek professional assistance.

{% linkable_title 1. CT sensor %}

  • Clip the CT sensor around either the Live or Neutral cable
  • Connect jack plug into either CT1 or CT2 socket on the emonPi
  • If the power reading is negative, reverse the CT sensor orientation
  • CT sensor cable should not be extended to avoid induced noise
  • For Solar PV install see Solar PV Application page
  • Learn more about how CT sensors work...

The clip-on CT sensors must be clipped round either the live or Neutral AC wire. NOT BOTH.
