- In this ESP32 project, I have explained how to make the home automation with Tasmota using ESP32 Alexa voice control relay and DHT11 temperature sensor to control 8 appliances with Amazon Alexa and manual switches. You can monitor the real-time feedback, room temperature and also control the relays manually from switches without the internet.
You don't need any coding knowledge to make this voice control Alexa smart home system. And all the tools used for this IoT project are FREE and you can easily download them from the Tasmota GitHub page.

During the Tasmota tutorial video, I have explained all the steps to make this ESP32 Alexa home automation system using Tasmota to control the home appliances with and without the internet.
You can control the home appliances from Amazon Alexa app from anywhere in the world. Only the ESP32 and Amazon ECHO DOT should be connected with the same Wi-Fi.
Anyone can make this Amazon home automation, as you don't need any coding skills to make it. Just flash the ESP32 with Tasmota Firmware, then configure the Tasmota dashboard as per the requirements.
So with this smart house system, without writing a single line code, you can convert any appliance to IoT devices and control them through the internet.
So, now you can just say "Alexa, turn on Light" to control the home appliances.

How to switch google assistant instead of alexa
Where is temp sensor reading in alexa
Thank You so much brother,from months to months i have searched for this Project on TH-cam,but finally got it.Thanks bro for these project
Nice work , please make a video how you build that PCB 4:08 or how make such PCB's , if you already made a video pls share a link it would be helpful. 👍
Well done great job👏👍
Thank you for the explanation
Welcome
Thank you for the explanation
how to connect -> Tasmota IR remote
Congratulations for 100k subscribers. 🥳🥳🥳🎉🎉🎉
Thank you for your support 👍👍
l like your video and l understand properly.🎉🎉👏👏👏😊
Indeed a nice job. Is this expandable to address multiple boards with 8 or 16 relays?
I have a situation which requires to address 32 relays and need to add a multiplexer/switch register.
Great tutorial. Keep up the great work.
Thank you
Sir, i wanna ask you, why the PCB viewer in video different with the Gerber File viewer? there is IR in the Gerber File but in there is not in video. Is that same or not?
Very good Job!!! Could you make this same project adding BLE? It will be the best and complete automation system.
Thanks.
thank you Bro really
Superb
Felicidades muy buen trabajo
Pregunta se puede hacer lo mismo pero para 12 canales muchas gracias

Do you encounter relay flickering issue(turn on and off split of second) during power up the board?
Which board are you using, ESP8266 or ESP32? in ESP8266 TX0 should be avoided for relay
Com port 6 is not showing.... How to solvd it
Sir Do I need to buy the Amazon Echo Dot to work alex? I try the alex add device on my mobile apps only no device located.
Yes. You need one echo device
Great project and works very well too. However, the IP address changes whenever there is a power outage and the router power cycles. How to set it right?
Pls don't generate the IP again and again.. once generated try to acces it with same ip
How many esp32 devices can be added in alexa for free?
Sir ESP8266 8 chanel pe bhi eak video banaiye
Facing relay flickering issues after connecting, what could be the issue? Tried different esp32 boards also different relay boards, same issue. Using 2.4a mobile charger as power source
It may be due to loose connection
it is from the bad wireing
it is from the bad wireing

Hi, I'm Brazilian. I would like to know if it is possible to connect two switches in parallel to command the same relay?
Como ninguém te respondeu,sim é possível usar interruptor paralelo, se preferir a resposta em inglês é dizer
@@vanderleisilvasantos5343 Salve blz? pois é cara eu acabei montando e funcionou legal. Tecla controlando o rele e por voz tbm. Pena não da para ter a temperatura aparente na alexa.
@@helbertmaik1894 salve ,não sei se você ainda tá mexendo com tasmota, vamos lá já rodei tudo não encontrei, como mudar a rede Wi-Fi sem perder a programação, exemplo montei um módulo tudo funcionando, quero instalar em outro lugar, aí preciso só mudar a rede Wi-Fi, aí começa o pesadelo não consigo faço o reset mais aí perde a programação.
Sir.how much the full home automation project.
I’m not able to connect it to Alexa don’t know why help me
Is it possible to add the push button for turn on / off all the lights?
Ok
Can be used multiple esp32 in a home, if yes, please let me know the process or make a video as soon. I will be highly obliged. Thanks
Okay
@@TechStudyCell hi can you please share your whsatpp please I have order pcb from jlcpcb and connected all the components but facing some problem please help me out
New subscriber here... i really like all your projects sir... may i know the value of the resistor in R19
10k
what is the cost of pcb ..
Can we use microusb to power the circuit instead of 5V Dc power supply?
Yes. You can use mobile charger and connect it with ESP32. It should be atleast 2Amp
@@TechStudyCell I follwed the same procedure as you. (For 4 channel) but whenever there is a power cut and power comes again. The 2nd relay is defaultly setting to off position. How to fix this?
Como podemos intercambio de ideas
Sir please make telegram group so we can suggest and discuss our problems with u and members
Okay
Hello how are you?
Congratulations on the content, I'm learning now on this IoT adventure.
I followed everything right in this tutorial, the tasmota is all configured, but the Alexa app can't find my ESP32 board, could you help me solve this problem?
Thank you very much in advance!
use alexa divoice for this
Sir agar ham manually on krenge then pin low rhegi fir sir application se state kese change ho rhi he 🤔isme xor Gate lga he?
It has pull-up resister to do this job
what is the cost of full circuit ..
What if when power goes off for a while and comes back.. Will th relay regain its previous state... I mean relays which where off while stay off and relays which where on will stay on....
Yes
@@p-tech8166 Actually i have automated my room using ESPALEXA, Blynk old version... I also have add A RF remote........
As we have to pay for every new device we add in New Blynk version and as blynk has launched a new version so i fill that now and then they will discontinue the old version... So was sreaching for a alternative.... So how will we add RF Or IR remote with Tasmota....???
@@burhanuddinbhiwaniwala618sorry I don't have any idea about that
@@p-tech8166 Whenever the power goes off and come again.... The 2nd relay is setting to off position defaultly... How to fix this?
@@vineelarepalli I didn't face any problem regarding this . You can try it by resetting the device
Bro how can I apply 16 channel relay
Hi my name is juan sebastian im a 11 year old kid from colombia and i like a lot your iot projects and i wanted to see if you could help with one project i wanted to do is automating my garage door so i can open it and close it through a button and through alexa or google home please could you help me.

Hello.
I would like to buy a ready-made platine from you, it is possible.
Hi
Your project is very nice and interesting.
I want to buy your PCB module.
How and where to buy it.
Can you share the link to buy pCB from you.
Thank you 🎉
I can deliver within India only
Touch switch kese bnaye iske liye
Fan dimmer control Google assistant nodemcu please sir Aisa project TH-cam per Nahin Hai
Pls do it bro its our college project
iam a newbie in this field, and i follow your instruction, and succes drive the relay with tasmota, but if i take out the usb cable ( for download flash), suddenly tasmota cannot connect with ESP32, and cannot control the relay, what happend?, can you support?
thanks and regards
After that can you control it with Alexa app?
@@TechStudyCell not yet try with alexa
Can we use Alexa mobile app to control the appliances without Amazon eco dot
No. You need a Alexa device
sir how can we connect google home with tasmota
Not showing logs help me
How much watt load l can give in its relay.
It’s rated for 10A but I think 4-5A would be safe enough
