Home automation eeprom system please reply

Dear Friend @ajmolhoque102
*Thank you very much* for your interest in our channel.
*_Q_* - _Home automation eeprom system please reply_
➡️ If you are asking about implementation of EEPROM feature i.e *_storing 'current State of Relays/Appliances in the EEPROM Memory_* in this project, Then you can use use *EEPROM library*
This library get “installed” automatically when you install the ESP32 boards in your Arduino IDE.
With the ESP32 and the EEPROM library you can use up to 512 bytes in the flash memory. This means you have 512 different addresses, and you can save a value between 0 and 255 in each address position.
➡️ Other method is -- *Preferences.h library*
We recommended using the EEPROM library to save data on flash memory. However, *the EEPROM library is deprecated* in favor of the Preferences.h library.
This library get “installed” automatically when you install the ESP32 boards in your Arduino IDE.
The Preferences.h library is preferably used to store variable values through key:value pairs. Saving data permanently can be important to,
- remember the last state of a variable;
- save settings;
- save how many times an appliance was activated;
- or any other data type you need to save permanently.
✅ In our upcoming Projects using this platform of Home Automation using Rainmaker, we'll try to implement this feature. Thank you very much for your kind suggestion.

Hey , i just found your viedo helpful for making this with ir remote,, is there any way by which we can make a smart rf signal sender,,( just like smart ir universal remote but in rf) basically a iot rf blaster

*_Q_* - _is there any way by which we can make a smart rf signal sender...._
➡️ Yes, you can create an RF (Radio Frequency) blaster, similar to an IR (Infrared) blaster. An RF blaster can be used to send commands wirelessly to RF-controlled devices such as TVs, fans, or any other appliances that use RF remotes.
But creating a Universal RF Remote (RF Blaster) involves a few more complexities compared to an IR Blaster due to the wider variety of frequencies and protocols used by RF devices.
One major issue is Database, Unlike IR remotes, where databases of codes are more common due to the standardized nature of many IR protocols, RF remote codes are less standardized and less commonly shared in public databases.
You can use *SmartRF Packet Sniffer* by Texas Instruments to analyze and decode RF signals.
🔗 www.ti.com/tool/download/PACKET-SNIFFER-2/1.9.0
➡️ You can also refer different open source IoT/HomeAutomation unifying Gateways like - OpenMQTTGateway, RFLink etc.
➡️ Pilight is a versatile home automation solution that supports many RF protocols. It has a broad database of RF protocols for various devices and can be a valuable resource.
🔗 manual.pilight.org/protocols/433.92/index.html
✅ Creating an RF blaster can be a fun and rewarding project, you can use *RC-Switch* library for Arduino, any 433mhz/315mhz/868mhz RF Transceiver module, any MCU Board like rduino or ESP32/8266 and try collecting and integrating databases for RF Remotes. Also look for any user created/submitted RFCode database in different community forums. All the best for your project. 👍

Dear Friend @ajmolhoque102
➡️ You can refer following excellent Tutorial by Rui Santos
🔗 randomnerdtutorials.com/esp32-save-data-permanently-preferences/
Modify the code to save the state of each relay. And you need to add one more handle to continuously update the status.
➡️ If you want to use esp32-preferences-library then, Use following Project's code for reference
🔗 iotcircuithub.com/esp32-preferences-library-tutorial/
//Create a namespace called "relay-state" with read/write mode
pref.begin("relay-state", false);
// read the Relay state from nvs flash memory
relayState = pref.getBool("state", false);
// save the LED state in flash memory
pref.putBool("state", relayState);
➡️ If you want to use EEPROM library then, Use following Project's code for reference
🔗 www.technolabcreation.com/eeprom-memoryandroid-app-and-manual-control-home-automation-system/
void eepromcheckstate() {
{
toggleState_1 = EEPROM.read(0);
if(toggleState_1 == HIGH) {
digitalWrite(relay_1, HIGH);
}
if(toggleState_1 == LOW) {
digitalWrite(relay_1, LOW);
}
