    This research work describes the development and implementation of an electrical energy consumption monitoring system for homes with the use of LoRa technology, which was installed in two homes located on Cacique Álvarez and Pablo Arenas streets in the city of Ambato. The electrical energy monitoring system is divided into three parts which are: end nodes, gateway and server. The end nodes are installed in the homes where they collect the voltage and current data, these measurements were checked with a multimeter where it was evidenced that there was a minimum error, then through mathematical operations the power and consumption in kWh (kilowatt-hour) are calculated, this data is transmitted through LoRa modulation to a hub or gateway, the latter, after receiving the information received from the end nodes, transmits it to the server through the light network protocol MQTT, on the server The data that was previously published in the mosquitto broker is shown in dashboards programmed in Node-Red within a web interface, which allows the monitoring of these variables (voltage, current, power and kWh) in almost real time for each home, This information was also stored in a database that allows a detailed record of consumption, the system also sends alerts in case of tect high consumption or when there is a failure in the supply of the electrical network of the homes, these messages are sent through the messaging platform Telegram, the system was put to the test during a period of one month where in the end it was verified that the kWh consumption readings coincide with what is registered by the electricity meter of the distribution company.
