“…There are several innovative technologies and platforms in the energy sector designed to support prosumers, such as (a) HEMSs like Nest (Google Nest), well-known for its smart thermostats which learn schedules and preferences to optimize heating and cooling for energy efficiency [ 19 ], and Tesla Energy, which offers solar panels, solar roof and battery systems, integrating with a mobile app for energy monitoring and management [ 20 ]; (b) DR and energy optimization services, like OhmConnect, which rewards users for saving energy during peak hours, integrating with smart home devices to automate energy savings, and AutoGrid, which uses big data analytics and AI to offer DR, distributed energy resource management and energy storage optimization; (c) P2P energy trading platforms, like LO3 Energy (Exergy), a blockchain platform enabling LEM for P2P energy trading, and Power Ledger, which utilizes blockchain technology to facilitate energy trading, allowing consumers to buy and sell renewable energy directly [ 21 ]; (d) predictive analytics and AI for energy management, like Bidgely, which utilizes AI and machine learning (ML) to disaggregate energy data from smart meters, providing personalized energy insights and recommendations [ 22 , 23 ], and Tibber, a digital electricity supplier that uses AI to optimize electricity consumption for its customers, offering dynamic pricing based on real-time market conditions; (e) platforms integrating LLMs, which are a cutting-edge area of development and not yet sufficiently investigated. They have not been applied to prosumers’ energy systems and thus we identified a research gap.…”
