thank you for your video, you saved me more than the seller which has nothing about controlling. The application is not very familiar, buttons can't be graphical arrange and a button can't control two states like a switch, pressed first time to send a code pressing second time sending another code. For the beginning it's good even like this. Thanks again.

Very nice video Csongor. Well done with all necessary detail. The pilot wire in our central vacuum is shorted somewhere. Since the wiring is inside the wall, I cannot repair it. The vendor said I have to rewire the system pulling the pilot wire under the carpet, inside the wall, through the attic and under the house crawl space. The cost of the wire will probably be $100, not to mention the cost of labor. They also sell remote vacuum turn on for $180. So I turned to IOT. Using your video, I made it to work. To answer your question about Dynamic IP of the ESP8266, I assigned static IP for ESP8266 in the router. Everything is working like a charm and I spent less than $10. To complaint, I do not like the Wifi TCP/UDP Controller interface. Every time we lose power, I have to press the reset button and reestablish the communication. It may not be the software issue. It may be hardware issue. Anyway, thanks again for the nice video. Keep it coming.

Sir you are a GOD I NEEDED THIS BADLY

Thank you very much, I appreciate you sharing the information.

If you want static IP, you can just tell your router to always reserve a specific IP for the MAC address of this wifi relay device.

Jó az angolod! :) useful videó :)

Hello, any way to arrange working as mode 2 AS default when i disconnect the power? Any idea?

This can be flashed with custom / DIY firmware, it uses serial interface to switch the relays.

Is there a way to get to permanent mode 2? Because after power cycling, need to press S1 switch again for it to enter mode2 and connect to your wifi ap or router.

Important: the Relay Board needs to be showing the RED diode and NOT the BLUE diode on the board. I was trying to switch the relay and nothing was happening. If you want to change back to mode 1 (with the red light) press S2 while booting the relay.

Hey great video very helpful! I was just wondering is there a way to communicate remotely using the app ie not on the same network as the module? Or is there a new version that does support this?

Wow, thanks for your awesome video project. :)

the manufacturer site is 100% in Chinesse. Could you use wireshark in order to scan the TCP packets?

Hello friend, the relays can be activated if you are at work or out of town through mobile data from the cell phone?

hello sir how are you 'sir when i send command via wifi tcp /udp controller light blik every timed on wifi module when i send command but relay is not working i have same module on relay board blue and green leds are still plz help me

This information is very very helpful. Many thanks for sharing

Thanks for the review I was going to purchase one but after your review, I don't think I will bother I will just design and make my own with an 8266-01 and two replays to switch when I want so thanks for saving my pocket

Would a 24V battery blow this up? Can it be used to switch a DC inverter toggle switch on and off? It would need to be latching, correct?

Hi sir. Mobile App can use continuously in free of cost?

If it is like the single relay version then you should easily see that two of the pins are not connected. One is ground because it gets its ground through the device itself and the other is the TX pin which is why your not getting a signal back.

Hi. Great vídeo tutorial. Thanks. I have a question: how integrate this relay with a Raspberry Pi and OpenHAB?

Olá comprei um módulo desses com 4 relés porém na hora da configuração pelo aplicativo ele da falha e não consigo configurar .

Red one and black one are arduino connected or power connected?

Can you help me with using the WiFi module to take in data from a acs712

hi there Just asking about the output wires how you connect them there 3 wire output on each switch. sorry for the question but I am new in this thing and I am interesting to learn thanks in advance

se puede poner entrada corriente 220V y salida DC 12V, 24V?

Kedves Csongor! Képzeld működik a redőny! Egyik gomb fel, másik gomb le! Van egy olyan funkció, hogy stop command after release button, ha ott beállítod, hogy a gomb elengedése után adjon egy relé off parancsot, akkor csak addig működik a relé, ameddig nyomod a gombot!

I have this, but there are no aps for iphone or mac, so therefore my vife cant turn on the light, its not that smart, any solution ? I cant use it on my pc ether! no apps i can find, except you have to have arduino running all time. Tell me if am wrong :)

Thanks for your video. How do you change back to mode 1? I didn't fint out yet

The ESP relay card I bought recently doesn't have a controller on the main the gpio from the ESP switches a transistor directly to control it

Can this unit be set up to determine or sense voltage as triggers? - ie; relay 1 high voltage signal, then relay 2 , then back to relay 1 and repeat ?

Kedves Csongor!Be lehet úgy állitani a kezelőfelületet, úgy hogy csak addig működjön a relé amíg nyomom a gombot? Egy redőnyt szeretnék vezérelni vele, úgy hogy az 1-es csatorna fel, 2-es le!

Köszi for the tutorial. Inwas wondering if i had to basically create my own controlling software and just download it to the ESP. Still one can download a very basic controll software. Thanks again.

I am trying to connect it to my home Wi-Fi but I can't. None of those Android apps work anymore. I took out the esp8266 hooked it up with an Arduino, and connected it to the home Wi-Fi using AT commands. After that when I put it back on the relay board, it connects to my Wi-Fi momentarily upon boot, and then disconnects. Any idea why?

How did you uploar code to ESP? I think all adapters to this small ESP needs additional switch or jumpers to upload code ;/

Jó az angolod! Szerintem rendelek egyet

The ESP8266 SmartConfig App doesn't work on Android 10... is there an alternative?

Top you are well. Stay safe have not seen much from you for a while.

hay algun rele wifi que tenga entrada corriente 220AC y salida de 12V, 24V DC?

Szia! Az lenne a kérdésem,hogy ha Androiddal akarom használni akkor van hozzá külön applikáció amivel tudom vezérelni a modult? Esetleg ebben tudnál segíteni? Köszönöm szépen előre is !

If I understood correctly, you have to be in the same LAN to control the device? I have purchased a similar, but 4ch device and was hoping to remotely control the PSU of a 3D-printer. What would I need to control a device like this via the internet remotely ?

Hii, very very nice video. Do you know if it has a pulse command; I mean on-off command to command a gate?thank you

hi Csongor! :) what's that board in front of your PSU? Can't remember in which video i've seen it, and what it is...

Szia! 10-15 db ehhez hasonlo, csak s1 reles modult kelle kapcsolnom, ugy, hogy 1 gombnyomasra mindet zarja, illtve egy masik gomb nyissa. Ez megoldhato lehet? Elore is nagyon koszi! :)

I want to know whether we can control the relay from any where (far distance) through internet & app?

Good video. Simple question..Can I use this relay to turn on 12v DC lighting via WiFi from my Android phone? Thanks in advance. Cheers!

Is there any wifi relay like that which uses 240V AC as main supply? I cannot find them on aliexpress. I only found 5v, 12v and 24v.

how to uploading code android phone 1 channel ?

Buona sera. Desidero sapere se è compatibile con App ewilink. grazie.

Szia! Remek a videó. Hasonló esp8266-os delay-es modult vásároltam, próbálom azt csinálni amit itt a videóban bemutatsz, azonban amikor az ESP8266 Smartconfig-ot megnyitom az SSID: után jelenik meg, és sehogy sem sikerül a hálózatot azonosítanom, mi lehet a probléma?

I love that power cord. Did you make it or buy it?

I have a doubt if i press relay 1 on after that i close the application then what will happen ,if the relay will continue remain the same state or it changes from no to nc pls replay me guys ......

What are the S1 / S2 buttons doing? Are they connected to any of the pins?

Kedves Csongor! Windowsra van alkalmazás, amivel tudom a relét kezelni?

Thanks for share

I have the ESP-01 (1Mb flash) and was able to upload firmware using both Arduino and Mongoose OS for additional functionality.

How do I activate the 2 relays in a custom code in arduino skect? What would it be like for me to drive 4 relays, since I only have 2 gpio?

Can I use this without INTERNET directly connected with app in mobile or without connected any router

Did you come accross a SmartConfig "unknown SSID" error? I can't get passed this point.

hello .. can someone help me please ? is possible to control a relay and for exapmle a step motor in the same time? becuase we have only one tx and one rx one the esp8266 module. can the arduino recognise the different data that the esp module is sending or is possible that the esp module sends a different data for each action? thank you in advance

Buongiorno. Desidero sapere se è possibile comandare tramite App Ewilink . grazie.

How to get the esp 8266 app to your mobile phone?

Can we connect this to heroku server with a Node.js web app and then we can control this from any part of the world using mobile phone with internet. Whenever we press the On button in the mobile phone, it should send command to Node.js web app in Heroku server. Then the web app will send the command to this module. Is it possible like this? If not possible, what else will you suggest ?

Does this replay work with ewelink on iPhone? Thanks

in this project router/modem is required or I can operate it directly by my phone(android)

SmartConfig app does not support android 9, is there another one could be used instead?

you can use this with the regular arduino firmware instead of the at firmware by removing the RX jumper and writing serial commands to control both relays, i forgot exactly how to but when i remember ill update this comment edit: here it is relay 1: Serial.write(0xA0); Serial.write(0x02); Serial.write(0x01); Serial.write(0xA3); relay 2: Serial.write(0xA0); Serial.write(0x02); Serial.write(0x00); Serial.write(0xA2); with this you can control them using Blynk IOT, remoteXY or homeasisstant, or even with another microcontroller

can't seem to find the app ESP8266 SmartConfig...

Hello while i was trying to connect using this app ESP8266 SmartConfig, it fails, ,but on the module, the blue light is on, and green is blinking, but even after multiple attempts to connect from my android app, it didnt connect, any guesses why?

I got that device, and got a payback for that because but it arrives 'broken'.: Symtom is Blue led from main board is not working ,... only red led of ESP is on. Do you know how to reset it ? Before taking the decision to flash ESP, I woul klike to know if somebody knows the consequence of that. If I flash the esp , will it be possible to have response from the main board Any help will be appreciate before flash the ESP

большое спасибо!

Thanks for sharing.. What are the difference of work with TCP socket communication or MQTT or HTTP support? Do you have any video tutorial about it? Thnks in advance and thnks for your time to share this kind of vids!

I followed the video, but unfortunately I got an error message again and again. "Esptouch fail". Have somebody idea why doesn't work well?

Hello Friend. Could you tell me if this device works with google home? Greetings from Italy

ESP8266 smartconfig can't read my network ssid and not allowing me to write it my self

To have a fixed IP address, just reserve the IP address that the module acquired first time, in the router's DHCP address reservation table.

You can locked down you IP address using DHCP. Assigning IP address to that particular MAC address.

Can I use these relay for ac circuits

How you can program this? How to upload arduino code?

Kedves Csongor! Szerinted nekem miért írja ki már az elején hogy Esptouch fail?

nice

how did you get to 8:04 you didn't explain very badly, tell us everything and hide everything

i succed to flash esp with espeasy web accès to config for http,mqtt ==ok esp works allone but no heart bit neither wifi When plugged in main boyard seems to be really broken i do not know how to reset main mcu

Hi dear, I've bought 1 esp8266 module relay 12v 1ch and 1 esp8622 module 12v 2ch. I have used both esp01 for other arduino projects. Now I have a genuine esp01 ma it doesn't work with modules. Please, can you send me sketch to write into esp with Arduino ide? thanks 🙏

What is the name of app

When I look at the devices connected to my router, my router gives me the option of reserving the current IP address for that device.

With the Blynk app (www. Blynk.cc ) aplication it funks wery good. Thanks for your video.

You CAN do http requests with this board with the right arduino lib and code

Why does it need extra, support circuitry... i thought it was WiFi on a chip... and its not!

10 minutes in and the board comes across as disastrous, in that it is out of date and cumbersome. To be avoided! There are widely available, inexpensive, modern and accessible alternatives with an API and (if ever required) customisable firmware. Thanks for the review.

Plz give me program

I use easyTCP

That doesn´t help ! 1. the app doesn´t run , 2. AP Mode is on Red, 3. what means the blinking-code ? how to see which state is the modul ? there are many questions but no manual. This one wasted my time (days)

Wi-Fi connecting mobile apps asking for password, what will happen.why?.

Dónde puedo ubicar esa aplicación para configurar botones relay1_OFF : A0 01 00 A1 relay1_ON : A0 01 01 A2 relay2_OFF : A0 02 00 A2 relay2_ON : A0 02 01 A3 relay3_OFF : A0 03 00 A3 relay3_ON : A0 03 01 A4 relay4_OFF : A0 04 00 A4 realy4_ON : A0 04 01 A5

What are you talking about? These can be subscribed to an mqtt server!

Thanks for the video, may I have your contact information? I am a direct supplier of these modules, as well as a supplier to all merchants distributing these modules, and I hope you can help us test the product.

Soon it will be supported by Espurna: github.com/xoseperez/espurna/commit/ec46b66c19c2d346aacdbae734011df9195c04c1

It wastes 2W of power for 2 realys, btw.
