Bro, based on your video I did same perfectly working for me! Kudos

[@TechStudyCell]

Great 👍

did u exactly do what they said, any problems u faced??? pls reply

Hello my friend, I really liked your video! Do you think it is possible to do this using a switch instead of a push button, to reuse the infrastructure of the house

[@devangchawla3053]

Thanks a lot Buddy!!....there came no mistake in ur code..and even worked very well....👍

[@SandeepYADAVggn]

This Project has issue. If we use manual control, the status of relays not upated in Alexa. i.e. If on the go I want to switch off relay 3 by switch, the relay will switch off but alexa will show its status as swich ON in Alexa App.. Even in case of manual operation of switch , the status of relay/lamp should be updated in Alexa App.

[@ganeshpatil5313]

Any update on this?

[@harrydutoit4907]

This project is awsome, It does however take a couple of tries to get Alexa to discover the device. I have a slight issue in that if you switch the relays on/off change the current state with the push button, the status change is not reflected in alexa. Any constructive input is very welcome.

[@Sailingon]

Just replicated your project and reversed the state, driving solid state relays. thank you for your work. Where can we donate to help fund you making more things?

[@sazamaut3321]

Bro... Do the same thing using Google Home mini...

Desperate to have at least 8 outputs please I could not add any!!!!! Also would love to have an LCD display to show on/off operation Thanks so much for a wonderful project I made one a few years ago but Amazon stopped supporting it and here you are! Best regards Erik

may you please make a video using LittleFs library to store switch status along with this marvelous tutorials. this is my humble request.

[@electronic7979]

Excellent project

[@TechStudyCell]

Thanks

[@dipaksonone3699]

Very nice explained sirji....

[@erspoa]

Hi Im really liked your project, I put it in two different places and it works normally. But this week I believe that there was an update to the echo dot 4 generation, so my two projects no longer find the devices. Already updated the libraries, restarted the two Alexas which are in different locations with different networks. Today I took the same codes and recorded them in other nodemcu and didn’t find anything else. Have you caught more cases like this? Hugs. Ícone "Verificada pela comunidade"

[@joshitoshi9835]

Thanks for the tutorial. I have already requested and i am again requesting for a detailed video on SAFE wireless 220ac solenoid water pump control system with water level and manual on/off button and that with 12v relay. All the videos available on youtube are with wired system which is not practical in most cases bcoz tank is usually at 3rd or 4th floor so running wires is tedious in that case. So please take a time and make one. Thanks

[@TechStudyCell]

Sure.. Added in to do list.. thanks

[@joshitoshi9835]

@@TechStudyCell Thanks for swift response and waiting eagerly for that video. Here are some points and specs to note: - Working voltage should be 12v dc - 12v dc relay must be capable of controlling 2hp solenoid pump - Must have water level indicator in terms of leds or 7 segment or small display screen. - Must have Manual switch to turn on/off motor at any time (can be further connected with ESP8266 relay to on/off with mobile phone) - 433Mhz RF module can be used as its cheap and its range is more than enough in my opinion but you can use any other module which you think is better than that.

[@karthikganjam296]

Thankyou so much, it worked perfectly for me, but one change is we need to add latest version of espalexa library

[@varunaggarwal1510]

can you please help me with it? its not working for me

Está de parabéns, sua automação tem código simples e eficiente.

[@akhiljames4863]

Any relay flickering issue on startup? You connected it to pin 0 and 3.

[@arnoldaddo2642]

Because I built a voltage divider fan regulator and wanted a platform that would see all four speed as one device(fan) and not 4 sperate relays. Can i use if statement and edit your sketch to do that by reducing it to one device?

[@niladri2202]

I think we should replace the push button system with a ir remote system Because that will be more beneficial And remove " if else " wifi connection clause.then we can use it simultaneously with an ir remote and alexa

[@fredisbaltais4429]

Hi. Fantastic job You done. Is it possible to added MQTT control?

[@TechStudyCell]

I think MQTT also can be added

[@TechStudyCell]

Yes. For devise not found error, you have restart the echo dot. I have covered this in the new video.

Thanks will Give It another go:-)

[@maazrehan5360]

Appreciated sir.. sir i wanna ask that, is esp32 is that powerful that we can use it regularly with in a years

[@TechStudyCell]

I have not tried that. But it should work.

[@joshitoshi9835]

Nice video, i have two questions here; 1. Can we make it three way switch by adding another manual switch? 2. Can more than one phones control this relay? for example i want all my siblings can also control my room lights and fan etc from their phone. If both features are possible i would suggest to make another video bcoz this kind of video tutorial is not available on youtube.

[@SSATechInTelugu]

Hi bro your project excellent working push button but upgrade to the the our project manual switch please take video I no English spelling mistakes thank you

[@realistik01]

really nice job, i bought a nodemcu devkit 1 but windows dont reconize it, i had the esp01 working goos so i assume my driver where good, anyway i did try to download all thenm and uninstall one by one and even that, nothing happen, i do have a blinking red/blue and i do see a wifi, witch i can connect but only telling me its a test page, any help ?

[@shantanumuni7344]

Excellent project, request same code which should work with Blynk, Alexa along with Google assitant together

[@TechStudyCell]

Thanks for the feedback. If you can control the relays with Alexa App, then why you need Blynk.

[@ambroribo6079]

Good day , it is Me again: The project is working very well but I found that if the relays are controlled locally by using the relevants discretes, Alex does not report the correct relays status. So by activating the the realys by their discretes buttons , I can not see the relevant status on the Alexa application on my cell phone. Is there any possibility to implement a real status feedback to alexa application please ? Thank for all . regards, Bye

Hello Very good project, Thanks a lot for sharing the code. Everything works perfectly. Can it be done so that when a channel is activated, the relay is on for 2 or 4 seconds? To control, Blind, Garage door, Curtain? If it's possible, and it is, but I don't know exactly how to write the code, I would pay for it. Thanks a lot Mr. Petrov

good day to all; I uploaded the sketch on my ESP after having changed SSID/psswrd and everything was fine and working very well. Later on I changed the device names BUT the names where not change in tha Alexa application. I did several changes: reload the original names, reset the PC / ide , power on/off Echo dot, removed the four devices in the Alexa App, uninstall Alexa App from my mobile BUT Alexa does NOT find_out the ESP devices anymore . Any suggestion Please ? Thanks in advance, Ambro
