My little project to switch 2 relays via esp 12 is running stable, however I notice on the attached diagram a 10k resistor and 0.1uf capacitor connected to the rest pin, can anyone explain what that is for ? is there any advantage to connect the rest pin with this resistor capacitor combination considering my project is stable ? could it give me a way to do a remote reboot for instance ? thanks for any response.

The capacitor holds the reset line low briefly during power up, in order to make sure the SoC performs a proper reset. If your module consistently starts up properly without the reset circuit, then I wouldn't worry about it.

Can please post the schemtic for controlling the realy (I iamgine its 5v )with esp12 (3.3v)
lua code would be nice too

Its all very basic stuff, but here its is, I am using 12v dc supply because the item I am switching has the same 12v supply, if you were wanting to switch 5v then no need for the LM2596 I guess.
relay=0
srv=net.createServer(net.TCP)
srv:listen(8080,function(conn)
conn:on("receive",function(conn,pl)
gpio.mode(5,gpio.OUTPUT)
if string.find(pl,"gpio5=0") then gpio.write(5,0) relay=0 end
if string.find(pl,"gpio5=1") then gpio.write(5,1) relay=1 end
conn:send(relay)
conn:on("sent",function(conn) conn:close() end)
end)
end)
