GPIO 0/2 flickering in home automation (need urgent help)

Postby Eden » Thu May 03, 2018 3:07 pm


I'm using ESP8266 for home automation using mongoose OS. Connecting 4 appliances to a single esp8266

I've connected a wall switch (not push button) to the GPIO 12/13 whose corresponding outputs are GPIO 0/2 which are externally pulled up to be able to control the state of the lamp not only with the WIFI but with physical input has well. The esp-12e running on Mongoose OS allow to sense the change of the Input (ON->OFF or OFF->ON) of the GPIO 12/13 and reflect this input change to the status of the GPIO 0/2 and then turning LAM on or off.

This setup has been working perfectly. But since a couple of day the the lamp is flickering (ON->OFF, OFF->ON intermittently). This is happening once an hour or so

Any suggestions how i can fix this?

We have had our PLCs used for home automation. We have not had any trouble reported using them in this type of environment.
