**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.

Hey can we control things independently
@@TechStudyCell Can you please tell me the board dimension?
Thank you for this project.
Our pleasure!
Thank you so match for your video
Much waited video
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
How to make voice automation with esp32 works on Google without any 3rd party app or website like not using IFTT AND SINRIC
Can you please share the source of circuit diagram i need to change relay dimensions to get pcb printed
Hi, I have a question, I need to used LCD so I need ports D1 and D2, but they already been used, so wha should i do.
Hi, the ESP8266 so near with relay didn't cause the EMI problem because of the AC power line?
does it trigger the relay if there is no internet in a loop ? which happens to me while using Blynk, if modem is off, the relay will trigger every 1 minute.
Thank you man really thank you so much
You are welcome
How can I add AC voltage switches which can control lights manually without powering the NodeMCU and relay
thanks a lot, you make my jam and jelly
Thank you for making such awesome videos, if possible please help making a combined circuit with light and fan controller as it will be really helpful
Noted.. Thanks
you're a lifesaver!!!!!
Very very impressive sir
Thanx from Morocco
khoya wach khdem lik mzyan?? khani n9dm projet ista
op bro
you really explain well
Very useful smart home system. Thanks for sharing
Hi bro, can you trigger a audio file (USB) with sonar sensor using NodeMCU or ESP32... Reply will be solicited.
I couldn’t get to set my esp8266 and esp32 running in my Arduino ide even after installing Python 2.7.3 and pyserial from adafruit. I have downloaded the drivers and installed the board in Arduino ide. The port is “com 28” and I think I used “nodemcu 1.0 module 12E” for esp8266 or there about! ( I am using CP2102 chip) The device manager shown that the hardware was properly installed and ready to use. If I try to open the serial monitor in Arduino it will never open, instead I will see “error com port 28 busy” If I upload code on the boards it pops out bunch of errors among which is “error opening serial port” or something like that.
I am frustrated, I need help please!
Sir, can use esp32 and 8relay module,8manual switches?
Thanks for amazing content sir
You are welcome
SIR I TRY YOUR CODE BUT WHEN I USE TURN ON IN GOOGLE HOME OR ALEXA ,
WHEN I COMMAND LIGHTS OFF THE LED BECOME ON IT REVERSE ,AS OF NOW I DONT USE SWITCH
Great video dear👍
Thanks
Hello, How do I integrate the library into the code? (when i type "", I can see that on your screen it changes to an orange colour font...but for me it doesn't...What do I do?
Hello sir,
I'm looking for smart switch for curtain motor 24v dc , please can you help me make this circuit/module?
Thanks
Kind regards
Please I really need help with this connection my presentation is on tuesday... I found out that after connecting everything all components read well except the diodes, it's like it's shorted. It reads in both directions when connected to the PCB and hence the relays don't power when plugged into 5v supply. My presentation is on Tuesday please I need help
Buenos días, perdón por no saber inglés. Mí pregunta es ¿éste sistema funcionará con Alexa o con Google, sin tener el servicio de internet? , gracias
Wow i like this project
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
until relay module I can able to control via voice command when I say light 1 turn on the "IN 1" turns on but the bulb connected from IN1-IN4 does not glow up pls let me know where i have gone wrong
thank you bro ♥️♥️♥️♥️
Can we do project with relay, nodemcu and switches only and removing transistors, resistors, etc as it needs electronic knowledge
Very helpful project
Thanks
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.
Thanks for your video, so awesome 👍👍🙏🙏
Welcome
@@TechStudyCell : 🙏🙏
hello friend, can you help me with something. when I do the project it works perfect. but when I mount it in my room that I make all the connections the manual function does not work for me. It is possible that it is because the cables that go from the ESP8266 to the push button I am passing them next to the alternating current cables 120 AC
not push buttons use only normal one way switch
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
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
Do we connect 8 channel relay to esp12e board oor it can be controlled by switch, voice please tell me
Bro … in a ideal mode nodemcu is disconnecting and connecting automatically… please give e solution
can you tell me about software for designing PCB.? please.
Excellent project,keep it up. Sir please make fm radio using node mcu esp8266 ,your explanation is very clear, thank you in advance.
Ok. Thanks

Bagus banget semoga ilmunya berkah pa guru..salam.
If you order to turn on, and It alread on, what its back? Turn off, turn on(mean do nothing) or answer "its on"?
I had a problem with Design
I have mounted all components
When I power up the system Only nodemcu turns on
Power led and other led aren't glowing and relay not working
Can any one help to figure out this problem?
tengo una duda, en el caso que los switch manuales los ponga a positivo en vez de negativo, habra algun cambio???
No change i guess
Great, thanks.
