How to program ESP32 using Arduino IDE
• Programming NodeMCU ES...
During the internet of things tutorial video, I explained all the steps to make this IoT-based home automation system, and how to connect Rainmaker with Google Assistant and Amazon Alexa app.
In this ESP32 project, you can control the relays without internet from the manual switches. ESP32 will automatically connect with the IoT cloud when the internet comes back.
If the ESP32 is connected with Wi-Fi, 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.

It works really well. Thank you for the code.
added OLED display to show status of 8 relay and WiFi connectivity, it works really well.
Unlike Blynk Rainmaker is really good. Blynk used to cause lots of issues if offline.
I thank you for this. Three days on the wait. Thank you and following every detail.
Welcome
I have been an ardent follower of your videos and have constructed most of your circuits. In this one, is there any way to remember the last state of relay before power cut?
I did it and it's working fine....I used the vin pin from esp to supply power to Relay module and used a 5v 1amp charger adapter to power up the esp...
thank u man last video i mention comments do rainmaker project now u done You are great
can u add more sensor related to home like door sensor security alram, motion sensor
Thank you very much for my first step of making diy smart home.
Respect!
Sounds like a great project to me. What would happen if I want the relay to act only for a second, since what I need is just an impulse, for example to open a gate
I tried this project and it really work and I'm really happy from it thank you for this video i just have 1 issue with this project is that when ever esp32 restart it sets all the relays to off mode. Is there any way to make it remember which relay was on and which was off . Please reply
What should I change in code to use Active HIGH relay? Because I have only Active High relay at this moment.
thanks for the amazing but i have a question in case i don't have an ESP32 board, can i use an ESP8266 instead?
If the Esp32 is off for some , would the project work with only manual buttons
Excellent very educational video.
Could you please make another one with the thermostat function.
With DS18B20 and also with DHT11
I thank you in advance
Was exactly waiting for this!! Thank you!
You are welcome
Can you try to add fan speed controller?
very amazing, but please help how to turn one of the switches into a push button like a doorbell button? thanks
I've done the same thing as you, but I want the led on the relay to turn off when it's done booting up.
can i use 2 complete modules of this proyects in diferents houses but with the same wifi and google assitant acount?
Hello, please I need help to fill *Sample-BOM_JLCSMT* and *JLCSMT_Sample_CPL1* files finally to order the pcb board with the assembly on the JLCPCB platform ... thanks in advance
Is it posible to connect multiple esp32 in 1 dashboard? Like the one we can do with blynk iot. Thanks in advance.
Great project. I got this working no problem. Is it possible to have 2 of these on the same network and within rainmaker? What needs to be changed in the code to make each esp32 unique.
Many thanks
regarding to your lora nodmcu project (Code_NodeMCU_Lora_TX_feedback) , i can program to nodmcu without error , but its restarting with

Hello once again my regards to you and your team and thank you for making us IoT gurus in our small world with your tutorials.Please it is possible to for the esp32 rainmaker keeping memory for the on and off switch functions like the other projects which remember their on and off state?My regards
Hello Tech StudyCell, can you help me with a 16 relay version? I already tried it but it gives me an error, I'm using the ESP32 38 Pin ESP WROOM 32 WIFI, Bluetooth, your code of 8 does load it but I have a 16 relay module and it won't let me load it. Could you help me with the code and how to do it? the connections please?
Hello, I don't have the status in ESP Rain Maker when I turn it on and off by manual switch.

Please can you tell us what is the parts in side PCB ?
At 8:19, after a 4 second press of the boot button, no text or barcode appeared for "4Relay_Button" sketch.
Hi! Nice video, could you teach how to conect two Relays and a stepper motor (or cc motor) to open, close (or set height with percentages) a roller blind?
Great video, I mounted it and it worked fine, but my esp connects to the internet only when they are connected to the computer by USB, when I remove the USB cable it disconnects from the internet. :(
Could you please share the Gerber for 4 relay module..!
Hii sir.. i have a problem.
Actually .maine esp rainmaker app me 8 switch set ki hai and alexa me bhi set higayi hai.but ab mai esp rainmaker me alag esp32 se 8 switch set kar raha hu to esp rainmaker me set to sari hojaa rahi hai.but alexa me shirf last wali 8 number ki switch set ho rahi hai.
Kya alexa app me limitations hai devices add karne pe?

Can u help me out with program and circuit diagram
Can you make a video of an IoT project with an ESP32 cam for video streaming and can monitor home security with face recognition or something else?
// define the Chip Id
uint32_t espChipId = 5;
In your code what does this mean please?
Will it work without Internet . Using the esprainmaker mobile app
rainmaker can support up to 8 relay board?
Thanks bro with this wonderful tutorials. Please how to implement local network control without internet?
Bro how to get the partition scheme as rainmaker for esp32 board
Can you please send the BOM and pick and place files for SMT services to use this pcb
Hi, when switch 1 is at ON state in rainmaker app than esp pin is also ON
When esp is deprived of power and when power re supplied to esp board the pin comes to OFF status.
And due to sync rainmaker app also goes to OFF status at switch 1.
Unlike blynk.
This should be other way around.
On resume of power to esp board the board should get all values from rainmaker to resume it's state after power is Normal to esp board.
nice video, only issue is that once net is down it becomes useless for any remote control mechanism, basically it becomes a dead switch just like our non smart regular home switches, at lease if the wifi is available irrespective of internet, then we should be allowed to locally use the controls, lik esphome or homeassistant or even tasmota, or esp purna, but rainmaker becomes uselss once you are without internet. This was only limitation otherwise it is very good overall.
I really like this project, thank you sir.
anna your videos are super doing a great job i have dought can i use esp8266 instead of esp32 it will work or not
Is it possible to increase more modules? 16 or 32 modules?
Bro i want fan speed control in esp rainmaker and please change using switch alternately use touch sensors
