Electronic Module for Control of Energy Source

The paper presents an electronic device to control a heat source as part of a system for the management of energy flows in residential premises. The designed system incorporates an energy model that calculates the energy flow through the surrounding walls of the room. The algorithm calculates the point of switching on or switching off the energy source, considering the mass and the required energy to make the temperature to a certain point. The power of the energy source can be regulated from 1 kW to 6 kW in steps of 1 kW. The module for control of energy source is developed based on the ESP8266 system on chip and connects to a predefined WiFi network. MQTT broker is used for communication between the system for management of energy flows and the module for control of energy source. The module subscribes to predefined topics and they are used to send the commands.
