ESP8266 Community Forum

I am using ESP-12 F in one of my project of watering where it gets connected to Internet and synchronizes with timeserver which run regularly to update to correct time, at defined time it performs an output operation to switch relay on, it also has feature to turn relay on using switch as an in input , kindly help as after some running the esp-12f would hang/freeze and not respond to any switch inputs until the entire module is restarted by powering supply on/off to module after some random time it sometimes runs without any freeze/hang for constant 7-8hours, is it any low memory that can cause or kindly guide what may be the cause of this

We need a lot more info then this - what language or SDK are you using for a start? There are about 12 different programming environments for the ESP8266 and a million ways for each of them to hang
