Smart thermostat company Tado is launching new AI-powered features that aim to help users heat their homes more efficiently. Tado says the AI Assist update builds on the company's existing Auto Assist options by introducing "advanced machine-learning" that "learns, predicts, and optimizes" heating in real time. AI Assist is available in Europe and the UK today for all Tado X owners at the same price as the company's existing subscription (£29.99 a year or £3.99 per month).
