In this true home automation project, I have shown how to make an IoT project using ESP32 Google Assistant Blynk 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.

Video on NEW Blynk + ESP8266 + IR + Sensor: • ESP8266 Project using ...
For this ESP32 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:
00:30 Control appliances with Google Assistant Blynk & IR Remote
01:12 Controlling relays with DHT11 Sensor and Timer.
03:21 Required Components for the Blynk ESP32 IoT project.
03:36 Circuit of the ESP32 IoT Home Automation projects.
06:04 How to set up Blynk IoT cloud for ESP32.
09:53 Source Code for the Blynk ESP32 IoT project.
12:51 Set up Blynk IoT Application Mobile Dashboard.
13:57 How to add Automations in Blynk IoT (Timer and Sensor )
18:52 Controlling relays from Blynk App, IR remote, and switches.
19:17 Connect Blynk cloud with Google Assistant using IFTTT
Required Components for this ESP32 home automation system
1. ESP32 DEV KIT V1
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 ESP32 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 ESP32 board and libraries as mentioned in the code.
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 ESP32 project, you can control the relays without internet from the IR remote and manual switches. ESP32 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 ESP32 projects which I will cover in upcoming videos.
