B4R Question Controll relay with ESP8266

[cloner7801]

Hi there,

I read in internet we can controll relay with esp8266 without any microcontroller

Can we controll a relay with GPIO0 and GPIO2 pins?

in this link you can see , but how can I program in b4r?

Can I programm with FTDI?

It might be easier, faster and cheaper with this...

Or this, if you need two relays...

How is it different than the example posted here: https://www.b4x.com/android/forum/threads/esp8266-relay-let-there-be-light.71696/ ?

Both Sonoff relay boards have the ESP8266 built in. If the goal is to control a light, Itead also offers this...

which also has the ESP8266 built in.

Plus, here's a far simpler development board...

Yes but I don't have place for put aruino and ..
I want to convert ESP8266 to a wifi with SSID and controll one relay with ESP8266

There is no Arduino in that example and it is controlled by WiFi. I'm not sure that I see any difference...

I think the "issue" is that the board used in the ESP official examples looks like an arduino (for compatibility with arduino shields).
I have a Wemos D1 mini clone, and every single example posted targeting the ESP board by Erel and others do work.
Users need to bypass this board physical appearance and think of it like any other ESP based board
