When the wind is straight at our window and it is pouring (not just normal rain) we have a leak.
It has to be repaired by a professional, however in the mean time I have a leak detection.
An ESP8266 programmed in ESP-Basic with just 11 lines of code sends a notification through IFTTT to my Android Phone. It really can't get any simpler as this !!!
