The H20me Smart Trial 1. Test how real-time water use
monitoring and online feedback could be integrated into the Perth BCP.
2. Test the use of real-time comparative/ normative feedback.
3. Greensense was the industry partner. 20

• Pulse head & data logger installed onto water meter at house.
• Logger notes a pulse every 1L or 5L used.
• Sends data through mobile 3G network

Implementation - Greensense View
• Launch Smart Meter Challenge dashboard • Extract water consumption & # occupants data in number of formats. • Compare water consumption between weeks through a weekly profile • 5-minute interval profiles that showed specific end-uses to be identified
(e.g. distinguishing toilet flush from shower from garden irrigation)

Results: Engagement
Engagement with dashboard lower than expected; • Letter & info packs sent as physical reminder of
smart meter challenge (Round 4). • Phone calls to prompt dashboard use (Rounds 4
and 5). • Letter insert in response to participants
forgetting log-in details/or not logged on to their dashboards (Round 5).

Results: Data Analysis
• Heat Maps - help identify anomalies & patterns of water use.
• Weekly Profile Comparison Reports - water use averages & maximums tabulated & graphed for 2 periods of time.
• Nature of this program means water reduction cannot be solely attributable to real-time data through online dashboard.

Results - Water Savings Most households made a water savings!
Note: Season effect on consumption - large decrease in consumption coincides with winter & not direct result of smart meter installation.

Participant Feedback Initial feedback encouraging:
“We have been using the dashboard for just over a week now and have been checking the dashboard on a daily basis. Seeing how we compare to other households is very motivating. When we first logged in we were above the average now we are below and trying to get lower - I don't know how they can use so little water - if you have some insights please pass it on!.
My partner has become very competitive about what we are calling the "Shower Peaks" on the graph; he is trying to use less water than me for each shower. When we first started I used considerably less water than him for showers now we are about even. So I think this Greensense meter has really helped him monitor his water usage because where I always think about my water usage he never did so it really has improved his water usage.”

Lessons for the future • Understanding meter limitations • Visual display of real-time data
& analysis for households must be used carefully.
• Effort required for successful engagement
• Carefully integrate the dashboard & data into eco-coaching
• Future programs can fully integrate smart metering with a CBSM BCP
