I am working on home automation project in which 6 AC(230V) appliances can be controlled via mobile.
i can easily turn on or off any switch using mobile, but some time randomly any appliance has been flashing in its off state.
i am using MOC3021 to drive the Triac BT136-600E(it is Sensitive gate,do not get non sensitive in my city),also using snubber circuit (C=0.01uF 400v, R=560 ohm).
i tried to increase noise immunity using 100ohm resistor between MT2 and Gate terminal of triac but did not work.
Following is the schematic of my circuit.
So now what can i do to get rid of this problem..?

i think there is a problem in display of circuit so if any one required circuit to solve the problem than let me know.
