**Here I can control all 4 relays manually with switches. But as I have used the free Sinric Pro account, so I can control 3 devices with Google Assistant and Alexa. To control the fourth device, you have to purchase 1 device in Sinric Pro.
**If you use Switch, then the Switch-2 must be turned off during the booting process of NodeMCU. But for push-button, there is no such limitation.
**You don't need any Alexa devices like Echo Dot or Google Home Mini. You can just use Google Home App and Alexa App for this IoT project.
Download Code for this NodeMCU smart house automation project from the following article
iotcircuithub.com/smart-home-...
During the internet of things tutorial video, I have explained all the steps to make this NodeMCU ESP8266 smart home system with Sinric Pro to control the home appliances with and without internet. I have made this Google Assistant control smart home system without IFTTT. If the NodeMCU connected with WiFi then you can control the relays from anywhere in the world with Alexa and Google Assistant. And you can also monitor the real-time feedback in the Amazon Alexa and Google Home IoT applications. So with this smart house project, you can convert any appliance to IoT devices and control them through the internet.
So, now you can just ask Google Assistant, "Hey Google, turn off lights", or "Alexa, turn on light". that's it.

@@TechStudyCell
Hey can we control things independently
@@TechStudyCell Can you please tell me the board dimension?
To connect more lamps you need a hub or server, por example the program home assitant in raspberry pi, and the custom firmware tasmota, and devices with esp8266 like sonoff to control outputs for control infinite lamps
thank you ♥️♥️♥️♥️♥️
lol my google assistant understood your command it's kinda amazing considering it as a hard time with my own voice?
Wow i like this project
Very very impressive sir
Thanx from Morocco
khoya wach khdem lik mzyan?? khani n9dm projet ista

बहोत बढ़िया
धन्यवाद
Sir it is the perfect video for home automation till now with Google and Alexa both but fan speed is missing somewhere pls try to make it , any how I liked this video very much
Thanks. Noted. But it will take time.
Grt sir ❤️
Keep watching
at the end remember to say, please come again!
😻✨ I try building it
Great..
Did you made this project?
Nice tutorial but is there any diagram for 8 to 16 lines or what is the max line that NODE MCU can handle? Thank you for the response
1 node Mcu can handle max 4 connection
Grate one.
Thanks
Giving switching control with nodemcu had lot of mal function. Relay Automatically turns on or off if some switch turns on from other room which means does not has physically connection to nodemcu Junction.
Sometime can't able to communicate with nodemcu needs to restart complete. It's really difficult to remove from Junction and reset.
Note : you can't find these issues with demo session , you need to test real-time which means need to connect in home switch board or Junction and where you using regularly.
Hello mate, I am very well impressed with your hands on experiment. Is there any clear document regarding this project? which helps us for Practical
bro yeh project work Kiya ki nhi tumhara
Hi project in future 🙂
PCB the components you solder in which all positions like that is not clear .... So can you do a video on PCB soldering the components....🙏🙏
Great tutorial bro, Can you make more advanced tutorial using sinric pro ?
Something like blinds, sensors, send ir codes etc.
Noted. Thanks
Still waiting for fan Speed control ❤️
@@yogendrajamsariya1193 I believe you are using sinric pro right ?
Go to examples there's a fan example test it.
@@yogendrajamsariya1193 I'm too busy these days, just give me some time and I will give you the best solution for your problem bro.
@@nightwing8164 😉 I am waiting bro ,
hello,,i'm from indonesia.i only know a little about arduino and nodemcu, but i like your tutorial
Thanks for the feedback
Nice video sir
Can control power supply switch also
👌👌👌
Great video👍
I had a question wrt the Channel Relay, is there a specific one required or any relay is fine. Since i have a relay module lying around but whenever i tried it doesn't work. Your thoughts.
5 volt relay
hey brother, thanks a lot for such a brief and awesome informative video, i have few questions though,
will the sinric pro be running for long years or it may be closed. for how long we could use the app? what if he just shut downs itself? like app closed
Ideally we dont need any third party link blynk or sinric. As you can host your own webserver to control things from your MCU
@@varunaggarwal1510 How to do that? Where can I learn that?
You are great!!!!!! Thank you very much
You are welcome
👍
♥️
Hi from Czechia, thx for videos..... But this is exactly what I need as a time relay, to automatically turn on different channels at a set time? Can you recommend software for this? Thanks
♥️♥️♥️♥️♥️
Hai ..sir please make a this program
How to program two light swrichs and fan switch with speed control in esp8266
Brother can you please make the same project with TUYA OR SMARTNEST.
Please make a video for automation using nodeMCU using IR , buttons and server, but without Blynk, and without Sinric pro
You can refer to following video : czcams.com/video/OJ4CzWyRQr4/video.html
Hi
Thanks for very good
Does any of those module work with zigbee ?
Please make 3 rellay with fan speed control video
I'm also working on IOT project,
Here there is one problem with this approach. If Wifi module or relay fail manual switches won't work.
🥳🥳
Can we do project with relay, nodemcu and switches only and removing transistors, resistors, etc as it needs electronic knowledge
thanks bro your project its amazing. i've got one question do you thinkt that its possible to replicate this project but using micropython?
for the ESP8266?
HI @TechStudycell
Hello sir, Thanks for the wonderful and useful project.
am created the same project, but am facing an issue... is that, when where the power (electricity) resumes, all the loads or relays turns to ON.
The node MCU not storing the last status memory.
is there any solution for that.
Op bolte
By this method we can operate from anywhere
Can u please make a project node MCU with tuya .
hei bro, excellent work, i don’t know where i made a mistake instead of lights turning on when i say turn on they turn off and vice-versa
Can you please share the source of circuit diagram i need to change relay dimensions to get pcb printed
can you tell me about software for designing PCB.? please.
terima kasih tutorialnya kak, bisakah kakak sampaikan cara mengaktifkan perintah suaranya?
I have esp 8266 Lolin v3 & i am facing problem in the video you use sd3 for switch 1 and in my esp8266 there is (S3) instead of SD3 what should I do?
Sir agr isme fan ko connect kerna hoga to kaise karenge?? Please make video for this.. 🙏🏻
