Thanks very much Tim

You are welcome. ;-)

Yesterday I ordered one of these
https://www.ebay.co.uk/itm/192059571... 4.m1439.l2649

They are cheap enough eh. ;-)

It will be a few weeks coming from china - I have other less interesting
jobs to do first anyway

I've often had stuff arrive faster from China than the UK? ;-(

I will certainly try your code.

I think it helped (me) to have played with Arduino stuff quite a bit
previously as configuring the Arduino IDE to the ESP was a bit more
complicated than most straight Arduino boards (and that included
adding the support for the extra boards in the first place).

Then after a couple of glitches (I tend to just 'experiment' my way
though such things with a quick research when I'm not particularly
sure) but had first the WiFi network scanner and then the WebHost /
switch working pretty quickly (and both units seem to be ok after
all).

I want to put an LED or relay on it just to see it actually doing
something from a mouse click. ;-)

Yes, it might be interesting, but I think I'm quite content with light
switches that go 'click' and don't need a linux box, UPS, switch and
access point to work ...

Hehe, quiet ... although I think some of this stuff can run
autonomously (once configured) and the Sonoff switches can be remote
controlled by a fob (that will be further away than the real
lightswitch of course). ;-)

Hi Tim,

I crawled through your code and could not find anything about reading
the analogue value and displaying it.
I don't know of it is particularly difficult but several of the web site
tutorials featuring this device give code for digital i/o but avoid
analogue. I even contacted Random Nerd about their training Ebook and
video course but he steers clear of analogue too.

Hi Tim,

No, there wasn't Bob, that's why I included the code (that wasn't mine
btw) so that one of the coders here could add it in for you. ;-)

I don't know of it is particularly difficult but several of the web site
tutorials featuring this device give code for digital i/o but avoid
analogue.

Oh? It's pretty easy ... or at least is was on the Arduinos. I believe
it uses a divider as the chip uses 1V so that 3.3v gives you a 1025
reading (10 bit).

https://raw.githubusercontent.com/no...DEVKIT_SCH.png

https://forum.arduino.cc/index.php?topic=445538.0

I even contacted Random Nerd about their training Ebook and
video course but he steers clear of analogue too.

How strange?

My board looks like this:

https://i1.wp.com/henrysbench.capnfa...er-Pinouts.png

http://esp8266.github.io/Arduino/ver...reference.html

"To read external voltage applied to ADC pin, use analogRead(A0).
Input voltage range is 0 — 1.0V." (or 3.3V on my 12E)

And a sketch that includes analogue read is he

https://www.teachmemicro.com/display...cu-web-server/

No reason why you couldn't copy and paste the right bit into your
first On/Off sketch.

When your ESP (or whatever) arrives, shout-up if you don't get anywhere...

FWIW, I put the following code on one of my ESP's and it worked ok,
returning a random value (I had nothing connected to A0 so that was to
be expected) on a browser (manual refresh):

"Sensor to Node MCU Web Server
Data:
18.00"

This is what I used:

https://www.teachmemicro.com/display...cu-web-server/

-----------------------------------------------------------
#include ESP8266WiFi.h
#include WiFiClient.h
#include ESP8266WebServer.h

// Replace with your network credentials
const char* ssid = "Your WiFI SSID";
const char* password = "Your WiFI Password";

ESP8266WebServer server(80); //instantiate server at port 80 (http
port)

String page = "";
double data;
void setup(void){

pinMode(A0, INPUT);

delay(1000);
Serial.begin(115200);
WiFi.begin(ssid, password); //begin WiFi connection
Serial.println("");

// Wait for connection
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.print("Connected to ");
Serial.println(ssid);
Serial.print("IP address: ");
Serial.println(WiFi.localIP());
server.on("/", [](){
page = "h1Sensor to Node MCU Web Server/h1h3Data:/h3
h4"+String(data)+"/h4";
server.send(200, "text/html", page);
});

server.begin();
Serial.println("Web server started!");
}

void loop(void){
data = analogRead(A0);
delay(1000);
server.handleClient();
}

Thanks Tim,

Looks straightforward enough. I appreciate your time!

You are more than welcome. ;-)

Hmm ... I have to really 'study' code to even get a feel of what it
does, let alone how it does it so I'll take your word for that. ;-(

I appreciate your time!

Np's ... especially as I have some projects in mind myself involving
some of the features you need. ;-)
