This article describes the design of a device that can switch, for example, the lights in a small parking lot or lights around a house based on\u00a0lighting intensity, time settings, light intensity at selected times, or sunrise and sunset times. The device also functions as a measuring device that measures light intensity (with a BH1750 sensor), voltage and frequency of the power line (with a PZEM-004T-100A measuring device). When the device is switched on, it measures the electrical energy consumption, current, active power and power factor of the switched device (also with the PZEM). Furthermore, the voltage, state and temperature of the battery that powers the device during a power failure (by the LC709203F module) and the temperature of the RTC are measured. The device uses the Adafruit Feather M0 RFM95 LoRa Radio<\/strong><\/a> and the components listed below. \"Switch<\/p>\n
