ST_Anything and WEMOS D1 mini Board (ESP8266)... HELP!

To all the Arduino + ST_Anything Experts and Gurus here…

first of all, I apologies if this is a repeated entry, but I spend some time an efforts looking for solutions and/or any answer and it result in nothing.

My situation is that im NOT able to see my ESP8266 (or any other new device) on the Classic App after I performed all the steps and instruction of the ST_Anything’s GITHUB (the read me file) and I DONT KNOW WHY!!! :’(

I already spend the whole week before and after work looking for a solution but i dont find it. So i have no other way than just ask into the forum.

I really apologies for taking some of your time by asking, but Im almos surrender and i don want to!!! I know that is possible!!
Please, any help is more than appreciated…

So far, this is what i do:
*Im using the “ST_Anything_GarageDoors_ESP8266WiFi” Arduino File
(Which is one of the most easy/simples and requiere nothing fancy to operate and/or additional Libraries, I think… ).
*I downloaded everything related to ESP8266 (this is not my first time using it. I love this little guys for my projects).
*I Linked my ST/Samsung Account with GitHub.
*I Copied/installed all the DevicesHandlers from Github to my ST/Samsung
*I already seated the ST Hub with an Static IP in my network (
*I already change the SSID and Password in the Arduino’s Code

  • I check on my Router/Modem settings and i see that the Arduino/Wemos Board is connected to my network.
    *I changed all the Router’s Information on the Arduino code (please see both images).

However, after all this, i dont see any new device installed/paired under the “things” tab in “My Home” on the classic app.
In addition, if i try to “add” a new device, the Hub dont “see it” on automatic mod or manual (by clicking on “add device manually” /others/ “SmartThing Shield for Arduino”.

Please!! Did i miss something!!??
Im attaching screenshots of the ArduinoCode and my RouterSettings.
Any help is more than appreciated.

You have to MANUALLY add the “Parent ST_Anything Ethernet” device using the ST Cassic WEB IDE. It’s in the ReadMe. Just follow those specific steps as it appears you’re very close.

Greaaaat!!! I finally did!!! I didn’t noticed that part of the readme has to be done inside the ST Developer web (I was looking on the app or something like else).

OMG, it feels so great!!!
Thank you so much, I finally did it… you point me in the right direction… I’m so glad!! Thank you!!!
I really Appreciate the help!!

I saw in ST Clasic app all the door’s Contact Sensors and the Temperature readings (I dont have the temp. Sensor connected yet, that is the reason of those readings)…
But I can’t find on the ST apps any “Button” to be pressed for the relays connected on the WemosBoard.
Did I miss something?? Is there any additional step to be done?
Please, see picture attached. Thank you!!

Click on the word “Closed” or “Open” as that will send a message to the ESP8266 to momentarily activate the relay.

I tried… But dint work!
I revised the code and I see that you are using Pin #2 and Pin#6 for Relays1&2 (respectively).
I armed an small circuit to see when the contacts and relays works, but only the contact are working fine (in the circuit and ST).
For some reason, the relays are not responding when I pressed the buttons.

Did i missed something on the code? (please, see the attached code).
Or their might be something in the DeviceHandeler??

Thank you!

This is the code that im using…
Contac sensor are working fine, but relays not.
Thank you

Also, thank you so much for the help and the “couching”… i really appreciated!! :wink:

What relays are you using? How are they wired to the board?

Im using some cheap Chinese relays, that I bought from Ebay long time ago, their are activated with a LowSignal from the Arduino/wemos board.

How ever, I also tried using a LED (connecting the negative lead/side of the LED to the Board) and it doesn’t work.
I also switch the LED of it position (just to double check) and does not work either.

Can you get the standard “blink” example a Arduino app to activate your LED? Remember to reverse the logic to active low and see if you can still get it to work. This will help to sort out the wiring.

Also, what shows up in the Arduino Serial Monitor window when you click on each of the garage doors? If nothing, then you haven’t entered the Arduino IP address and port correctly in the parent device’s settings.

Thanks Dan,
Regarding the circuit and the “blink” logic,
I already do it prior to write you on the forum.
Also, I have mine own code/sketch and circuit to test all the basics functionality of this board and is working fine. Also the led by itself.

I will try what you mention of the serialmonitor.
I’ll check what the serial monitor shows when I click the buttons, but I think that it says nothing.
I do remember that when I close/open the contact sensors there is something typed on the serial monitor, but I dont remember that this happens when I pushed the buttons.

I also saw the button changing of state when I open/close the contact sensors. I dont know why I’m not capable of active the board outputs when I press the buttons on the ST app.

Also, did you checked my code? Is anything wrong on it? How can I see if there is any issue with the DeviceHandler? (I change nothing on your device handler… so is supposed to be working just fine).

Thanks for the help and advice!!!

Your sketch’s network section looks strange and may explain the issue you’re seeing. Are your ST hub, Router, and ESP8266 all on the same LAN? Why do you have such a strange gateway and dns server address? Usually those are the same address as your router’s LAN address.

-Yes, all of them!

-I fill this from my router’s data.
I attached a picture of it in this thread.
Fid you recomend me to change it??
Did you think this is the issue?

Here, my router settings.

Again, thanks for the help!!

Those are the router’s WAN settings. You need to use LAN settings. If your router’s LAN IP is, then use that as the gateway and dns addresses in your sketch.

Ok, Gateway and DNS addresses is going to be both the same… got it!!

I think that this is exactly the LAN IP, but I have to double check!! I will try all.of this as soon is I get home.
I hope that this resorve the issue with the buttons… :crossed_fingers:

Thanks for the help!!

I finally can says that… “It’s alive!!!” “It’s aliveeeeeeee!!!” :joy:

I finally founded my error. I doesn’t was the gateway settings, it was the ESP8266 Board’s IP itself!!
I seated an static IP for the STHub and I pretty sure that I also did this for the ArduinoBoard.
However, I looks that I forget this part… lol
So I saw in my network that the board have other IP inside the network, I changed exactly to the one that I inserted on the code and… whal-a!! Is working like a charm!!

It took me a while to find the error, I was focusing on the code, but the error was in the DHCP settings for the board.

It was a really great lesson for the kids at home… “never surrender; hard work pays off”!!

Really appreciate the help Dan!!! :wink:
