4-Channel WiFi RF Relay Switch Module DC5-32V w/ 433MHz Remote

Power the module with 5-32V DC. Download the manufacturer's app from the iOS App Store or Google Play. Follow the in-app instructions to put the module into AP (Access Point) mode, connect your phone to its network, and then select your home's 2.4GHz Wi-Fi SSID and password. The module will save these credentials and connect to your router, enabling remote control. The 433MHz RF remote can be paired separately for local backup control.

While the exact amperage rating isn't specified in the provided data, the relays are designed for typical appliance control and feature 1000V isolation. For safety and longevity, it is recommended to check the relay's datasheet for the specific current rating (often 10A or 16A for similar modules) and ensure your connected load (lights, motors, heaters) does not exceed this limit. The module's own power supply must provide up to 380mA when all four relays are simultaneously energized.

Yes, the module's wide input voltage range of DC 5V to 32V directly supports common 12V and 24V DC power supplies, which are standard in automotive, marine, and industrial control panels. Ensure your power source can deliver sufficient current (up to 380mA peak). The internal circuitry regulates this down for the logic and Wi-Fi components. Always observe correct polarity on the input terminals to avoid damaging the board.

The scheduled timing functions are typically stored locally on the module's microcontroller after being set via the app. Once configured, these schedules will execute based on the module's internal clock even if the Wi-Fi connection to the internet or your router is temporarily lost. However, remote control via the smartphone app from outside your local network requires an active internet connection and the module to be online.
