RaspberryPi Owl Intuition Electricity Project

  1. 1. Using the... RaspberryPi and the Owl Intuition Solution to Track Electricity Usage A PiFan Project
  2. 2. The Problem Statement ● Large bills – £486.97 in 6 months! ● How do I track usage? – Meter is outside.... not a simple solution – Bills are quarterly/half-yearly.... too slow
  3. 3. Copied from www.theowl.com The Owl Intuition Solution ● Always on ● Enables – Tracking of usage – Data collection – Download of data – Online graphs – Great for analysis ● Great solution.... but I still need to go look at the usage – I want to be notified
  4. 4. Solution Options ● Buy another electricity sensor – :( I like the owl solution it works well ● Write a program on windows laptop to interface to Owl? – It'll crash after a week :( blue screen, etc – Not a windows programmer – how do I send mail or even get a compiler? ● Write a program on Linux laptop to interface to Owl? – Better, but my laptop uses lots of power – kinda self-defeating ● Use the Pi! – Low power – Linux based – Easy coding
  5. 5. The Solution The Owl Website (for Config) The Owl Sensor The Owl Sensor The RaspberryPi Transmitter Receiver
  6. 6. The Solution Explained The Internet
  7. 7. The Python Program on the RaspberryPi ● Written in Python to make it easier for the Pi Community to use ● Instructions to interface kindly supplied by Owl manufacturers – Based on IP Multicast ● Email achieved using Sendmail ● Solution works nicely ● Program listing available here: http://www.raspberrypiusers.com/?p=7484
  8. 8. School Project Idea ● There must be a link between: – Eco-schools – Computing – Cost-savings – Electricity ● Link school power usage profiles and share tips – Calculate cost and profile of electricity usage, show effect of switching off lights – Show the impact on the environment – How many carbon tonnes of trees does the school use? – How many trees need planting to offset (5 per tonne per year)? ● Demonstrate Programming on the Pi or other computer
  9. 9. One Possible School Experiment Plan ● Monday ● Wednesday – Hook up Owl Intuition & Pi to network – See if the electricity usage dropped – Present to kids the effect of electricity use – Explain in terms of £ and trees on the environment – Highlight power used at night ● Tuesday ● Thursday – Show kids the profile of Monday's – Review power usage again, plan to reduce electricity usage for rest of day and night – Identify peak times – Focus on the computing at work, show the Pi, talk about how computers work and – Explain the link of power usage at school, how the Pi is work carbon offset and £ cost ● Talk about Python and – Experiment by look around the school for Scratch Programming items with power on ● Friday – Review power usage and cost for the week – See if the power usage has dropped per day – Calculate £ savings if any – Summarise how it all worked – Show where to buy the Pi, Owl, etc – provide leaflets for parents
