The LUPUSEC-XT relay with power meter is used to activate and deactivate third-party devices. For example, you can connect a lamp to the relay and programm the relay that it is alarm, time, or temperature controlled. Additionally, it is possible to control the relay via your mobile device. Due to its small chassis, the relay fits into most in-wall patress boxes, i.e. behind your light switch. https://elecena.pl/product/18819984/12023-lupusec-relay-with-power-meter 2021-06-15 https://elecena.pl/product/18819984/12023-lupusec-relay-with-power-meter 2025-02-02
