During the Tasmota tutorial video, I have explained all the steps to make this NodeMCU ESP8266 smart home system with Tasmota to control the home appliances with and without the internet. I have also shown how to connect Amazon Alexa with Tasmota to control the relays with voice commands.
So with this smart house project, without writing a single line code, you can convert any appliance to IoT devices and control them through the internet.
Now you can just say "Alexa, turn on Light" to control the home appliances.

I am very new to this...
How are you powering on the nodemcu after it has been configured? Direct AC current wnt do it.. so another DC power adapter?
Hello sir can I use touch switch module in the place of push button or traditional switch, if yes then please make a video on it or just share a circuit diagram. Thank in advance.
i got this to work, i just could not get the esp32 with 8 relays work at all. i like to know can i use the smart life/tuya app to work with it?
Very nice video Sr ,but why do i need to add 2. BC547 Transistors (4 no)
3. PC817 Optocuplors (4 no)
4. 510-ohm 0.25-watt Resistor (4 no) (R1 -- R4)
5. 1k 0.25-watt Resistors (5 no) (R5 -- R9) for this project .Can't i control the relays directly from the esp8266?I'm a dummie in electronics!!! :(
Hi, I'm trying to do this with NodeMcu esp8266-12f, but I don't understand, the relay output is always on and doesn't act on the switch, can you help me?
This is what I want to do but with lora modules. Can I connect a esp running tasmota to a lora device so the lora sends mqtt?
hello! I can't get the model to work when using a toggle switch. when I connect it to ground, it makes the device reset. can you help me with this problem?
Thanks for the awesome video it was easy and well explained ^^ I made a bit diffrent project but this helped me out a lot =) It made me a subscriber aswell ^^
Thanks sir, 👍 I done this project..
Hi I asked a question sir, how to connect touch switched in the place of manual switches, and also I want to know that is it necessary to connect the usb also through power or laptop, becoz when I working with laptop realy is working fine but when I removed the usb and connect the circuit with power supply it don't dim the light realy not doing click sound and off led light. Sir please remove, I already purchased all devices so, it's loss for me.
by the way thanks for sharing new genaration
why app alexa dont detect to esp8266 if the echo dot is not conected? thanks
sorry im really new in this, can be done with outlets and a relay module of 6?
Excelente todos tus aportes. Gracias. Espero poder hacer alguno de tus proyectos. Una pregunta, los interruptores de pared de 220V quedan anulados? O hay forma de seguir utilizando? Gracias
Thanks, here relays are connected with 220V circuit. And switches are connected with ESP8266.
Suppose you want to connect fans and other appliances is it the same ?
thank you, big help
it works for manual and with the website but it's not working with Alexa and my Alexa app says no device found
Great job and Nice explanation sir👍
Thanks
I've planned to make this entire setup to my newly constructed house. Will there be any issues or it can work forever?
This is the easy way to configure an esp8266 with Alexa and Tasmota. please can you do the same project with Sinric Pro, Thank you
Привет! Подскажи подойдёт Echo Dot 2nd Gen?? Или обязательно 3nd Gen??
i use ESP32 module erro is invalid of packet (0*46) what can i do to work tesmota to esp32 module
Nice video ❤Thank
Power supply how Amp Required maximum ?
I noticed JLPCB now has aluminum for heat dissipation. Are these pcbs as strong as FR4?
Single-sided aluminum PCBs are intended for power LEDs. Maybe also for power transistors.
But the aluminum PCBs are harder to solder.
Bro working this project real👍🏽✨✨✨✨🤜🏽🤛🏽 i made this project simple
SSR 40 DA 3-32 v DC is active low relay module or active high relay module??? please reply
Active low
hello, nice project, is that possible to get the complete schematic, i need to make my personnal PCB, best regards
I am getting problem. When power off and device starts it doesn't power on correctly and does not connect to wifi.
No matter how many time I restart.
But when if pulled enable pin down and pulled up while power is on device started.
Thanks, why it losses its wifi connection after disconnect the usb, and nevert connects again.
After that can you control it with Alexa. Make sure switch2 turns off during reboot.
Hello Techstudy cell
How can we add a function of gpio state recall in case of power outage.
It would be nice to see Lamps which were Turned on before power outage to be turned on too when power is restored.
I hope you understand me friend
This project already has this features.
Here is can see the voice command overrides the physical switches.. IS it possible to use Alexa to on/off light when the physical switch is ON. Means first priority is to be the switch.if it's on then u can use voice commands
In this project there is no specific on & off position for switch. And the switch is connected with the esp8266. So when you press the switch, it will just change the current state.
@@TechStudyCell so as my switch board is installed in my room whats the way to add this integrated module to existing switches board
after time it shouts down and i need to reset it to work again. why is that?
ok i understood, but if nodemcu fails then how to operate manually
Great tutorial, i have a question. Is it applicable for esp 01 for just 2 switches?
Yes
Hi bro I need your help some of the files can't download
hola, una duda, yo no tengo el echo dot... porque la app del telefono no detecta por si sola a la ESP8266 sin el echo dot?
debe detectarla, es independiente de que tengas dispositivo Alexa o no.

Please check the circuit
Hi... Can we control fan speed with tasmota
Через ШИМ сигнал, например через твердотельное реле или симистр
i like this project, but i have a problem when i connect it with alexa app, when discover devices always fail "no new devices found" please help me how to solve this problem.
You need a echo dot, first check if the device are already connected in Amazon Alexa App
The tasmota can work only with the app? Without the echo dot ?
No.. you need echo device
@@TechStudyCell Thanks
You can try with Home assistant and their mobile client if you don’t want to use Alexa
