This advanced module operates on both WiFi (2.4 GHz) and RF (433 MHz) frequencies, allowing users to control connected appliances remotely via a mobile app (such as Tuya, Blynk, or a custom IoT platform) and RF remote transmitters.\u003cbr\u003e\u003cbr\u003eEquipped with four high-quality relays, the device supports the switching of 220V AC appliances, making it ideal for controlling lights, fans, pumps, motors, and other electrical devices. The ESP8285 microcontroller, an upgraded version of the ESP8266, enables WiFi connectivity, ensuring compatibility with voice assistants like Alexa and Google Home. The 433 MHz RF module provides a reliable manual control option without requiring an active internet connection.\u003cbr\u003e\u003cbr\u003eThe dual-mode operation allows flexibility—users can operate the switch via a smartphone app when connected to WiFi or using an RF remote when offline. The onboard mode selection buttons enable easy configuration, while the built-in AC-DC power supply ensures stable operation without requiring an external adapter. With its compact design, energy efficiency, and robust wireless communication, this 4-channel WiFi + RF relay switch is an excellent choice for home automation, industrial control, and IoT-based smart switching solutions.\u003cbr\u003e\u003cbr\u003eThe H3V4F is a compact and efficient 433 MHz wireless receiver module designed for various remote control and wireless communication applications. Operating on the 433 MHz frequency band, it utilizes Amplitude Shift Keying (ASK) modulation to receive data. The module offers high sensitivity, with a typical operating voltage of 3.3V, making it suitable for battery-powered devices. Its small form factor allows for easy integration into space-constrained projects. Common applications include remote controls, home automation systems, and wireless security devices\n\u003cdiv\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eTechnical Details\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eMicrocontroller: ESP8285 WiFi Module\u003c\/li\u003e\n\u003cli\u003eWiFi Frequency: 2.4 GHz\u003c\/li\u003e\n\u003cli\u003eRF Control: 433 MHz RF Receiver\u003c\/li\u003e\n\u003cli\u003eRelay Channels: 4-Channel Relay (Individually Controlled)\u003c\/li\u003e\n\u003cli\u003eRelay Voltage: Supports 110V-220V AC and DC load switching\u003c\/li\u003e\n\u003cli\u003eRelay Current: 10A @ 250V AC \/ 10A @ 30V DC\u003c\/li\u003e\n\u003cli\u003eControl Modes: WiFi (Mobile App), RF Remote (433 MHz)\u003c\/li\u003e\n\u003cli\u003eVoice Assistant: Compatible with Alexa, Google Assistant (via Tuya\/MQTT)\u003c\/li\u003e\n\u003cli\u003eApp Compatibility: Tuya, Blynk, MQTT, Home Assistant\u003c\/li\u003e\n\u003cli\u003ePower Supply: Built-in AC-DC module, supports 110V-220V AC input\u003c\/li\u003e\n\u003cli\u003eConnectivity: WiFi (802.11 b\/g\/n) \u0026amp;
