It is known that a large sector of the population keeps their electronic equipment connected to the power supply for prolonged periods of time. Even in many households, devices such as wireless routers and/or voice assistants are kept switched on every day at all hours even though they are not in use or at nighttime. As a solution to this problem, this paper introduces automation alternatives based on IoT (Internet of Things) making use of the NodeMCU board, a relay module, the Sinric Pro application, Google Home, or Amazon Alexa mobile applications, and smart speakers from Google or Amazon companies. As a result, it was obtained that the 4 proposals are efficient in terms of easy implementation and reduction of electricity consumption around 30% annually. This research helps families to improve their energy efficiency and daily productivity through IoT.
