      “… How much will it cost?”

      Here’s an example

      You have an emonPi3 energy monitor

      emonPi3 energy monitor

      6 clip-on CT sensors + an emonVs voltage sensor to monitor power

      100A clip-on CT sensor
      emonVs voltage sensor and power supply

      And 2 DS18B20 temperature sensors

      Encapsulated DS18B20 temperature sensor

      Real-time data from the emonPi3 is logged to feeds. A feed lets you view data recorded over a period of time.

      6 feeds log the power used over time

      00:00 24:00

      Another 6 log the kWh used per day

      Mon Sun

      And 2 feeds for your temperature data

      00:00 24:00

      You have 14 feeds in total

      £311.70 hardware, ex VAT
      × 20% =
      £62.34 of emoncms.org credit
      ÷
      £14.00 / year 14 feeds × £1.00
      =
      4+ years of credit included

      emonPi3 with emonVs voltage sensor, 6 × CT sensors and 2 × temperature sensors = £311.70 ex VAT (£374.04 inc VAT).
      20% = £62.34 of credit. 14 feeds at £1.00/feed/year = £14.00/year, so the included credit lasts over 4 years.
