Hi I am planning to design a home automation device. It is just a simple LED lamp that can be turned on or off from the internet. I am looking for the cheapest possible way to build it.
I have used ESP8266 and nodemcu previously, but these IC's from espressif look very costly to me. I do not want any SPI or I2C on the wifi module. I only need 1 GPIO pin with wifi ability. If possible a low power one will be nice.
So what are my options here other than ESP. Or do you know any cheap version/part number in ESP?
Kindly help me out
Thanks
Hey I am also in india only, I can rather use ESP8266EX IC directly on my PCB it is just 99Rs, but still is there anything cheaper than this? may be a chinese knockoff?
For my application ESP8266 is still an overkill, because it has spi i2c etc.. I just need something with one gpio pin and wi-fi capability
You are in india right, to try the ESP8285EX, i bought quite a few of thos for less than RS55, from chandni chowk market kolkata

PermalinkDid you consider using the ESP-01 module? it cost less than 2 dollars here in india.
