🛡️ Safety Features
Over-Temperature Protection
Shuts down at 60°C
Over-Current Protection
Trips after 5 seconds overload
⚠️ Important Safety Warning
Before starting the setup process:
- Do NOT connect the extension board to mains electricity (220V).
- Perform all configuration and programming while the ESP32 is powered only through USB.
- If possible, remove the ESP32 module from the extension board during programming.
- The extension should only be connected to electricity after firmware upload and configuration are completed.
This prevents electric shock, hardware damage, and unsafe operation.

Install Arduino IDE and ESP32 Support
Download Arduino IDE:
https://www.arduino.cc/en/software
Open Arduino IDE and go to:
File → Preferences
Add this to Additional Boards Manager URLs:
https://espressif.github.io/arduino-esp32/package_esp32_index.json
Press OK.
Open Boards Manager:
Tools → Board → Boards Manager
Search and install:
ESP32 by Espressif Systems
Select the board:
Tools → Board → ESP32 Arduino → ESP32 Dev Module
Install Required Libraries
Open Library Manager:
Sketch → Include Library → Manage Libraries
Install:
RemoteXY
SinricPro
Create RemoteXY Cloud Token
Go to:
Create a token and replace it in the code:
#define REMOTEXY_CLOUD_TOKEN "YOUR_TOKEN_HERE"
Setup Telegram Alerts
Create a bot using:
@BotFather
Then get your Chat ID:
https://api.telegram.org/botBOT_TOKEN/getUpdates
Insert your credentials into the firmware:
const char* TG_BOT_TOKEN = "YOUR_BOT_TOKEN";
const char* TG_CHAT_ID = "YOUR_CHAT_ID";
Setup Alexa Control SinricPro
Go to:
Create four switch devices and insert the credentials:
#define SINRIC_APP_KEY "YOUR_APP_KEY"
#define SINRIC_APP_SECRET "YOUR_APP_SECRET"
Upload Firmware to ESP32
Connect ESP32 via USB.
Select the port:
Tools → Port
Upload the code.
📱 Remote Interface
RemoteXY interface used to control sockets and monitor current, temperature, and energy.
Connect the Device to WiFi
Connect to the access point:
Smart IoT Electric ExtensionXXXX
Open:
http://setup.local
Configure WiFi.
Connect Using RemoteXY Mobile App
Use the Cloud Token to connect the device to the RemoteXY mobile application.
Final Step
- Disconnect USB.
- Reinstall the ESP32.
- Plug the extension into 220V.
The system is now operational.
