Sonoff Safe Voltage Smart Switch Module WiFi

Sonoff Safe Voltage Smart Switch Module WiFi

The Sonoff Safe Voltage Smart Switch Module WiFi (SV) is a versatile low-voltage switch designed for 5-24V DC power supply. It supports both AC and DC control via power supply separation (welding required) and includes GPIO pins for secondary development. Although it lacks 433 RF functionality and a shell, the Sonoff SV offers affordable and reliable smart home control by connecting appliances to the cloud through your WiFi router and the eWeLink app.

With this module, you can remotely turn devices on or off, set countdowns and schedules, and automate your home with smart scenes triggered by environmental sensors. The device supports LAN control, allowing on/off functionality even without internet access. Compatible with Amazon Alexa, Google Assistant, IFTTT, and Google Nest, it’s a flexible solution to upgrade your low-voltage appliances into smart devices.
