"First of all, sorry for my poor English "
I want to make something simple (i think).
I want to make a "device" that i can switch a button via phone app from far. Not the same wifi lan. But i dont know what i must buy. I search for esp8266 and i see many many modules etc.
With some words i want:
[list=]
A device to connect in my wifi
One app (i make with appinventor or blynk), with one button*
One relay (when i puss button from my app, relay close the circuit)[/list]
* I dont want the circuit is ON/OFF. I want to close the circuit while i hold the button. If i touch up the button or close the app, the circuit opens again to default position.
==============================================================
PS. I want to make this for one reason, if its allready something please tell me. I have a garage door with a remote control. But i want to open/close from far and i want to add something straight in door circuit. So i want to make the above device and leave in my home that is in area of garage door. So if i press the button of my app, the esp8266 active relay and close the circuit in my remote control switch (like i press it), and the door will open.
Look in skitch
