Hello, here is my code to monitor electricity and send sms on state change boolean electricity_status = 1; //remember if light goes we want every voltage so it is 1 - light prevents off state and gives 5v when light goes the relay goes 0 boolean device1_status = 0; boolean device2_status = 0; …

how to send Alert and avoid doing it second time (loop)?
