Thanks to the Internet of Things, we adapt production to consumption and optimize consumption. As a result, energy bills are reduced. The energy produced is used more efficiently and the emergence of renewable technologies is promoted. Another ecological advantage is that electricity providers can now rely on the Internet of Things to provide behavior-related information via a Smart Thermostat and, based on predictive algorithms, adapt consumption by remote triggering. orders to connected radiators.What are the key areas in which manufacturers can save money via the Internet of Things? Is it possible to estimate the magnitude of these savings?
