hi @Costas !
Yes i´m using 4 pins of the arduino, two pins for the sensor, one for the relay who control the misting system and other to control manually a ultrasonic humidifier.
Do you mean a Wifi adapter like this?
or a wifi module like this?
@Costas I´m testing right now your sketch of “auto reset for blynk” hope this work. I will write the update.
