Nest, a smart-metering company acquired by Google earlier this year for $3.2 billion, today announced a deal with Electric Ireland that will see free Nest thermostats offered to the utility company’s customers with a two-year contract.

Speaking at the Web Summit conference in Dublin today, Nest founder Tony Fadell claimed the deal will enable up to 1.2 million Irish residents to save money on their bills.

The Nest device tracks user behaviour and monitors room temperature to automatically optimise a home’s heating for greater fuel efficiency.

Fadell was quick to point out that Google founder and CEO Larry Page has no intention of using the data collected by the Nest devices.

“One of the big discussions we had with Larry was what we should do with the data,” he said.

“With Nest products, we’re invited into the home, like a guest… so it’s very important to have trust. Nest will stay Nest, the data will stay with us – the data won’t flow to Google and the ads won’t flow back,” he added.

The financial details of the deal were not disclosed.
