Can you make video about linking esp32 to smartthings app
Excellent
Thanks
Thanku sir wonderfull
Welcome
complimenti per il tuo lavoro. volevo chiederti se è possibile comandare anche i motori delle tapparelle? Grazie
How can we apply the same (getting the feedback) while using the manual swtiches (that take power from home service panel) ?
Thanks
if the power goes out do the switches remember their state? i.e if it was on before power loss do they turn back on on power resume and vice versa?
Can I use NODEMCU v3 instead of Esp32? What will be the changes in the code for it .
I want to use NODEMCU v3 board and control 8 channel relay without blynk or any IFTTT apps
you produce such great videos!!, how hard is it to add Blynk into this, as I am converting a camper van project and want Alexa voice control but also use Blynk that allows me to have battery status, solar charge status, turn valves on etc from a central iPhone/iPad screen in Blynk (just learning and your videos are a great help...
. thank you in advance for your help
nice, how can you apply this to a real life situation? If the switch is turned off you can with the Alexa turn it on the lamp? thaanks
sorry, But can you break it down more, if eventually i want to use it for a 220v appliances thanks.... because your diagram show a 5v dc switch
I understand that we can control fr bothe places..BUT...what happens to the manual switch logic.. if turn on the manual switch and then switch it off from internet?
Very good Bro, please make the same video without Alexa device, control with mobile through alexa
Already done. Links shared in description.
I have 2 channel relay module which says 5v . I tries using them with esp8266 but it is not working properly. I think because esp32 and 8266 have 3.3v output only... what should I do??? How to use 5v relay with 3.3v ???
If there is no internet even then also the manual switch either works or not
can I use doorbell switches as push-button?
please make a video on wi-fi universal remote using esp8266 nodemcu & Alexa
ok, I would like to know if you have a link where I can buy the components on Aliexpress? I really liked the project, congratulations 👏
hello, I really liked your project! I tried using the same code for my setup but I’m having trouble with it because Alexa keeps discovering espalexa devices that no longer exist. How can I fix this issue?
Nice project work perfectly,Sir can you update this project with add credentials without hard codeded.
Impressive and super useful as usual.
Can you make a tutorial how to increase esp32 pins using 16ch multiplexer please ?
Ok. Will start work on it.
@@TechStudyCell thanks bro
Hi I had an issue when uploading
The program is bigger that allowed for esp32
Wich programa you use to design your PCB?
hi buddy..as this video..its means the esp32 is powered with 5v?
Great project
But I have a question
Agar hamne relay 1 ya 2 ya koi bhi relays ko on kar rakha h via manual switch or electricity jane ke bad dobara ati h to kya vo relay activat hongi jo hamne manually ya blink app se on karke rakhi thi ?
Can we use push button or electric switch with same code? Please reply
Is there a way to communicate with an inverter DC compressor? 2kw power

How to connect the Google home with same this process instead of alexa
is it compulsory to have echodot to add this switches
Can this same be used for powerplugs
do you have a code for one relay module only? Because I only want to control one light bulb
Hey can you please suggest me how can I use Google assistance without ifttt because it's only letting 3 applets
thanks . but can we do this without echo dot? caz in the video the echo dot was restarted to identify switches. whats the use of echo dot in this project?
Hello, ROK!
I have no Echo Dot. I did this project using the Android app Amazon Alexa and the switches weren't found by the app.
My smartphone and switches are on the same wifi. And I restarted both (smartphone and switches). Alexa coudn't recognize the switches.
Hy. Is it possible that we make two 8 channel PCBs and use it on amazon alexa app to make 16 channel home automation ?? Or in other words can we use multiple 8 channel control boards with multiple esp32 to make many channel home automation
idont have Alexa speaker can I able to use this code for phone controlling
Great video. How to make the lamp automatically turn off after 30 minutes?
Basta colocar como uma tarefa em sua assistente virtual, Alexa ou siri ou Bixbay. Ou seja… coloque: Alexa, acender luz do quarto, desligar após 30 minutos de ligada!
hello, when I compile I get the error "
button1Handler was not declared "and so on with all of the following (buttonNHandler). I followed everything step by step, load the libraries. What could it be? Thanks excellent video!!
Wifi + Alexa app video please 🙏
This Great Man.. I made it, But only problem is, it cannot work if Echo Dot is off....
Is it possible if echo Dot is off it can work through alexa mobile app...
a question can be put an esp 8266 instead of an esp 32
Bro can you modify this project with controlling all appliances with dedicated Android app and also entering wifi credentials through app not from the code. Please try this project
Preciso disso para um projeto de automação. Onde consigo uma placa igual com 10 canais?
Ou vc tem no canal alguma automação com placa de 10 canais?
Pode linkar?
Abraço!
Wow great work,, how about a assistant
Can this be done using Google home app also??
Will it update the status after connecting internet again i mean What if internet is disconnected and button is on and connected with internet again will it change status on Alexa?
Bro the wifi in esp32 board not auto connecting when we switch off hotspot and on. is there any way for that?
Sir, i have one dout, instead of using ESP32, if we use ESP8266, will the project work 'with and without internet' ?
What a great video, is the app made by you ? If yes what platform do you use and if you have a video for it I would be helpful
I meant fir I mean for the smart home system where you use the app to turn on the lights
Bro can we control fan speed use thi project ?
can we make alexa and google home automation with nodemcu8266 like this without sinric pro
Is it possible to do this project with Google Home instead of Alexa?
thanks Sir
Welcome
My Alexa echo dot 4th generation could not search devices, please help me out. Thanks
Can u add eeprom to this please sir because this is the best project without any third-party app or platform only eeprom needed.
Thanks for idea😊 does this system remebers it's past state when power goes of and comes back?
No, but soon I will make the same project with Tasmota, there it can remember the previous States
I'm eagerly waiting for that please can u make it..I'm ready with parts to make it for my room😅
great video but manual switch design have issue that always turn on and off one way in different meaning where switch on it turn relay on where switch is off it turn relay of it cant turn relay off from switch where switch is off
Google home useing can you do
Bro alexa+blynk app +manual control home automation video podugha bro
bro how are you , thank you very much for sharing such knowldge ,now the 8 way relay code i have tried it was uploaded to esp32 everything ok i am able to ping the ip address , but i am not able to add in alexa ,when i search for new devices but it says not found new devices, i have deleted from the alexa before i have uploaded even after also not able to find new devices , i just checked that your new code 10 hours keep alive wifi led ,after 10 hours it was gone offline
thank you
Very nice project. Is it possible to make it with 24 relays instead 8?
No. You can connect max 10 appliances
That worked well especially when sinric is expiring. I see that I have an echo dot in my living room, so all devices there work but without an echo dot in the same wifi, the devices fail to operate on wifi. Any solution to that?
Same problem sir my siric expired
can you please provide the pcb design please
Hello sir i am an college student and we are going to work on a ev project so i need this kind of this to switch on/off car and control all the feature. so can this circuit be helpful

ok.
Or can it be used for air conditioning
Hello i need help here WiFi.mode(WIFI_STA); error message exit status 1
'class WiFiClass' has no member named 'mode' where is the problem?
Superb video ❤️
Can we do this project using 4 relay module??
Just by adding only 4 appliances in the code??
Yes
Hi Friend, congratulations from Brazil ! I have one question , if my internet is out I have some option to turn on my ligths?? Something like manual solution ?
If there is no internet then you can control lights from switch manually.
is it compulsory to have echodot to add this devices
أهلا وسهلا بك مشكور .
I want order pcb with assembly but told me that you want some files is not on like with Gerber file could you please send me it
sir pcb mangbane me custom duty kitni lagegi and isko pay kese karenge
hey.. can i use nodemcu esp8266??
Great job. I want to apply this board for a simply PIN mapping on ESP32 and use it in Home Assistant for the switch automation. 1 - Do you think your board can work in this case? 2 - How can I order your board from your provider? Thanks.
Thanks. for Google Assistant process will be different
Thanks for your reply. I'm not talking about Google assistant but HOME Assistant. It can work just with relays and ESP 32. I already did it. But I was instreded in your board but I don't know if the transistor and other component can interfere. I really appreciate a suggestion. Mario
What range are control it
bhai ec project mi aik relay ki modifation kesy ho gi ?.....door lock kay ley...jab bhi on karin to 3seconds bad khod off ho jay plz help .code kesy modifi ho ga?
