#57033 hi. i built a $10 DIY Wifi Door Sensor with this manual http://www.simpleiothings.com/10-diy-door-sensor/
it is working at first, but not working more than 12hrs.
this is what it log out when i press button when its "freezes" (i try it with button not with door sensor)
see last attachment
on 14:20 i start pressing the button and it only says that pin, level, calling and send nothing. what is this mean? previous pin, level, calling messages appears by itself! i press nothing back then.
this is debug version of nodemcu.

i was try it with these 3 boards

flash nodemcu using ESP8266Flasher.exe

can anybody please try this manual and make a door sensor and try with debug and see if it hangs on not? i need sensors like this bad. thank you. sorry if wrong forum
