Can you provide this code ..

Kya yaar sab angrez ke chode hi ban jate hai. Ama Angrezi me hi sikhna ho to Kisi Gore ki video na dekh le.. 😡🤬

Does this solution still work with Alexa?

alexa is not discovering devices

thank you you are the only one that explained properly on how it works

Any idea if this is possible with the Ethernet w5100 shield rather than wifi? Thanks

sir. eik video push button aur blynk par banaye plz..8 relay wala..aur wifi code upload karne ke bad mobile se dale.aur wifi reset button option be ho

That's badass. Just hardwiring relays into your electrical system. Forget buying smart devices. Forget about them losing their link

thanks big chap.

Thanks for the video. The "circuit diagram" link is broken. :)

4:10 where did he connect the relay's VCC yellow wire on nodemcu? He showed all the wire connections but skipped showing the most important yellow wire connection on nodemcu.

bro. really helpful. working perfectly

Google home and Alexa dono par kese kam karega please Bata do

Sir link open Nahi ho Raha please help

halloo thank you for your sharing knowledge everything ok why esp node mcu getting wifi offline after 5 hours

can you add 8 additional push buttons as an alternative to toggle the relays on and off on the same module ?

Its good, But cannot use Actual purpose, its having a drawbacks... After a power failure it will never get the previous state back... This may occur some bad incidence... could you try to save the current state to store EEPROM (MCU have a storage facility) and restore through Void Setup ()... I will appreciate that effort and it will become more useful... Hoping your reply..

Is there any way we can chat? I am creating a project and i just want to know whether i have the write understanding of what i need and where to start. You would help a lot! Thank you!

Can you still use the regular switch in parallel with that relay? If for example there's no internet connection.

sir i have a question will this work on the alexa app?

Hello can we use 12 volt relay module for this?

Please can you post the ciruit diagram? The link you posted doesn't function.

please update photo & circuit digram

Please help me I am using 4 relay board with Google assistant....🙄

hi, this is very awsome application i try to make it esp8266 nodemcu , 8 channel rely board , Amzon Alexa ,with properly installed but Problem is that esp8266 not show in sowftware in alexa what i do to make it with regards mansoor shah lionssgpk2@gmail.com

I have 16 relay board and d1 mini there is no uv pin I try 2 saprate power supplies but relay only light up but not work There is no jummper in this board and no jdvcc

Can it be worked with only the Alexa Android app only or it needs any Alexa device for work? I tried with Alexa app devices(i.e Relays) not showing in the app. Please let me know if you have an updated program for the same.

Are you pedal ing something

not working anymore

How can I interface 12 volt relay with nodemcu.

Thank you for sharing your project. I want to know why the code gives me an error. It appears that it is the switch.h library I don't know about programming, but I want to use this project at school. That's why I am writing to see if you can help me. Thanks in advance. I downloaded the echo-master file and used the ino file that is there. If another process has to be done please give me the steps to follow. I am already using my esp8266 and it works with another alexa code. But with this I have problems. I'm interested in this one because it has 8 relay and in the way it did in code I think alexa must find several devices because I saw that in the video you gave her orders to turn everything on and off everything and other additional instructions.

Hi, I have a question. can i power up a 5 volt 4 channel relay module with a 5 volt 0.7-0.8 mAh wall type charger, which is basically use for charge the simple mobiles. If yes, then how i connect, i mean what will be the circuit diagram. which wire will be connect with the vcc and which wire connect with the ground and which wire is connect with the ESP8286. OR, ESP8266 nodeMCU board 3.3volt is sufficient for 4 channel 5 volt relay? i am try to built a home automation project. Thank you very much. Please help me

Nice job Done Sir

so you're saying that the VU pin handles up to the allowed current of the USB ?!!? something like 500mA !?? if that's not the case, what did I miss ??

I cant see circuit diagram. Reupload pls

how to connect eco dot 3rd generation

Nice work Hitanshu :)

I have a problem to join eco dot 3rd generation....... any one help me please

Can we programme the same code on Arduino mega

this is 8 relay. it can be extend to more than 40 channel relays ?

can we control this relay board from anywhere or is it just LAN?

Hello, my query is... How many relays can you control?

Great Video! Thanks for sharing. Link to circuit diagram is down. any chance of getting info?

Jdd vcc connected to vin right

Jdd is connected to ??

Bahi yh kaya faltu ki video h 😷

If one were to build several of these would the relay names clash with each other? For instance would RELAY1 on UNIT1 appear to have the same name as RELAY1 on UNIT2? Would there be an easy way to identify each UNIT in the code from say the MAC address or something unique to each ESP chip, and then write that into each RELAYname?
