ESP8266 Project using Blynk Google Assistant with Timer and Sensor | IoT Projects 2022

In this IoT project, I have shown how to make a NodeMCU ESP8266 Project using Blynk Google Assistant with the timer, sensor, and IR remote control relay with real-time feedback. You can also control appliances without internet from IR remote and manual switches.
To try out the FREE trial version of Altium, click here - www.altium.com...
For this home automation project, I have used the FREE plan of the Blynk IoT platform and explained all the steps to use Blynk Automation to control the relays with sensors and timers.
During this Internet of things tutorial video, I have covered the following topics:
01:52 Control appliances with Google Assistant Blynk & IR Remote
02:33 How to set time delay in Blynk for timer control relay.
03:52 Temperature control relay in Blynk Automations.
05:07 Required Components for the Blynk ESP8266 IoT project.
05:30 Circuit of the NodeMCU ESP8266 control relays.
06:41 How to set up Blynk IoT cloud for ESP8266.
08:15 Add Automations in Blynk IoT Cloud (Timer & Sensor ).
11:34 Source Code for Blynk ESP8266 Home Automation project.
14:00 Set up Blynk IoT Application Mobile Dashboard.
15:07 Connect Blynk cloud with Google Assistant using IFTTT
Required Components for this ESP8266 home automation system
1. NodeMCU ESP8266
2. 4-channel 5V SPDT Relay Module
3. TSOP1838 IR receiver (with metallic casing)
4. DHT11 temperature sensor
5. Switches or pushbuttons

Important points:
1. You can turn ON/OFF the automation anytime from the Blynk IoT app.
2. IR receiver sensor must have a metallic casing. Otherwise, you may face issues while trying to get the Hex code.
3. The Blynk Automation will not work if the NodeMCU is not connected to WiFi
4. You can control relays with switches & IR remote if WiFi is not available.
5. Install the correct version of the ESP8266 board and libraries as mentioned in the code.
6. If you use latched switch, then during reset the switch-2 (D3) must be turned OFF.
7. Please watch the complete video, otherwise you may face some issues.
**Please take proper safety precautions while working with high voltages.
During the tutorial video, I explained all the steps to make this IoT-based home automation system, and how to set up automation in the Blynk IoT platform.
In this NodeMCU project, you can control the relays without internet from the IR remote and manual switches. NodeMCU will automatically connect with the Blynk cloud when the internet comes back.
You can use any IR remote to control the relays, just get the HEX codes of unused IR remote buttons, and control the appliances with those buttons.
This smart relay module PCB can be used for different ESP8266 projects which I will cover in upcoming videos.

Good Job Bro, First of all thanks for sharing you knowledge and educating people. Nobody shares their complete code gerber files etc. Hats off for that. Can you make a similar project without blynk, with tasmota/codes with IR remote. Your earlier project was really good, but it dont have the IR remote and Lacthed switch code...

Good work, But how can I set a specific time to turn on a device. Example, if I want to turn on a light at 5:30pm then how can I do that?

[@TechStudyCell]

You can add automation in Blynk IoT app as shown.

[@Snakeeeelegend]

WOW , Cool project can u make it with RF Wireless controller cause i wanna make a remote controller for water air conditioner which has no remote and it should turn on and off from other room !

[@bharathn_achar]

sir i have a question who will esp8266 know the real time status of Switch whether its ON/OFF which sensor is used to analysis the real time status please do guide us

[@fineasmrvideo9301]

What if I want to turn all the buttons on at once, as if all the switches are turned off with one button. This is what I need.

[@muhammadnor4135]

I really like your very useful project, thank you.!

[@rhodiumindia2066]

I decibel the time and I always control with IR remote and Google.

[@i-56mohith13]

Automation option is not showing in BLYNK IOT platform. What may be the reason, could you please explain 🙁

[@commandolee3608]

Explain plz, the old blynk could be Controlled using only a single Mobil phone wt it's hotspot to the nodemcu Control, but the new blynk needs to be connected to a separate wifi or another mobile hotspot before the phone the new blynk app is installed can function... Why is it not connecting directly wt the single phone??
