Water-saving gadgets are getting better at keeping water out of their homes.
The number of people using smart water meters has risen dramatically over the past decade, with nearly 3 million people in the United States and more than 9 million in Canada reporting they have taken water-management steps to help them save water.
But the number of water-savings devices available has been declining.
The U.S. Consumer Product Safety Commission (CPSC) released a study in July 2017 showing that only 23% of households with smart meters had installed water-saver devices, a drop of 17% since 2013.
“We’re seeing the adoption of smart meters fall,” said Chris Haines, director of research at Smart Meters International, a non-profit research and development company that conducts research on water-efficiency products.
“The consumer products industry is not as engaged with the technology and its benefits as the manufacturers are.”
The industry’s continued slow progress comes as the number and price of smart water-meters continues to fall.
The most popular model for smart meters, the Smart Meter Plus, is a $99 device that costs about $100 when it goes on sale in the U.K. and Germany in December 2019.
The device, designed to measure water usage from a distance of 10 feet, is sold by three major manufacturers, including Samsung, Sony and Philips.
A similar model, the Tachometer, is also available for about $60 and has the same technology.
But it costs about 10 times as much.
In the U.”s market, the $99 Smart MeterPlus has seen sales of about 100,000 units, according to Smart Metings International.
But Smart Meting estimates that the Smart Metering Plus has only seen a modest increase in sales since its launch.
The Tachimeter has seen a steady increase of about 1,000 to 1,200 units per month, while the Smart Thermostat has seen an increase of 2,500 units per day.
In a new report published in the Journal of Environmental Quality, Smart Metaling International estimates that smart meters have not made any significant impact on water usage.
But it also found that there are some smart water meter models that are able to reduce water usage by about half.”
While many of these devices are only a small portion of the market, they represent a significant portion of total water-use reductions,” said Hainess.
The report found that the smart meter “generates a significant amount of energy” when it measures water usage, but the data collected does not allow for accurate water usage information.
In the case of smart devices, Hainest said, the amount of water that is saved depends on the device and the level of the water in the system.
For example, an outdoor smart water thermostat that uses sensors to measure temperature and humidity in the home, can save up to 30% of water use when compared to the traditional thermostats.
But the Tampmeter can only save about 20% of its usage when compared with the traditional meter.
Hainests said the new report does not address the issue of data privacy and privacy issues that have been raised in the past.”
Some smart water models that use sensors to track the temperature of the home also have a privacy issue. “
It is not perfect.”
Some smart water models that use sensors to track the temperature of the home also have a privacy issue.
When the sensor readings are shared with a third party, the information can be used for commercial purposes, like to determine the optimal use of water resources.
Smart Meting International estimates, for example, that the TACHmeter can save about 60% of the data it collects when it analyzes the temperature in the water system.
And while it can save 30% in water use, the data will remain private to the company.
While the Smartmeter Plus is an improvement over traditional meters, Haineres said the TAMP-Plus, which uses a different sensor technology, is still “a pretty expensive product” that could potentially be better suited for home use.
Haines said he has seen smart meters “in the home for years and years” and said the technology is still not “the gold standard” of smart meter technology.
The Smart Metals International report also points to the need for more data-sharing between the meters and third parties.
“There’s definitely a need for data sharing and for consumers to understand what they’re getting for the money,” said Davenports.
“Smart meters need to be a product that works for everyone,” Hainés said.
The smart meters’ continued decline could be a signal of a larger trend.
The average household is saving about 40% of their water usage in the last five years, according for example to the Environmental Protection Agency’s water-storage report released last week.
And the average water bill in the US is about
