WiFi Relay + RF

Dual Wi-Fi and 433 MHz RF Control

This in-line relay switch module combines 2.4 GHz Wi-Fi connectivity and a 433 MHz radio frequency receiver in a single enclosure. It allows connected electrical circuits to be controlled via mobile app, voice commands, or 433 MHz wireless RF remote switches.

Installation and Wiring Requirements

The module operates on an input voltage of AC 90 to 250 V at 50/60 Hz and supports a maximum current load of 10 A. All wiring must be performed by a qualified electrician with power disconnected at the main circuit breaker. The unit requires both Neutral and Live connections at the input terminals (L Input, N Input) and supplies both Neutral and Live from the output terminals (L Output, N Output). Wire terminals are protected by an outer cover secured with screws.

Indoor Enclosure and Placement

Housed in flame-retardant ABS V0 plastic, the module measures 88 x 39 x 23 mm. It is built strictly for dry, indoor locations and must be kept away from water and high humidity. It provides switching for indoor lighting, small appliances, motorized curtains, or automated gate circuits that do not exceed the 10 A threshold.

App Setup and Remote Pairing

Initial configuration requires a 2.4 GHz Wi-Fi network and the Tuya Smart or Smart Life app. Once connected, the relay can be automated with schedules and timers, or integrated with Amazon Alexa and Google Home for hands-free voice control. RF 433 MHz remotes cannot be paired manually at the receiver hardware; pairing must be completed through the RF Remote Control Settings menu in the Smart Life app while the device is online. The unit supports up to 10 paired RF remotes.
