The TP-Link Tapo S112 is a compact smart switch module designed to bring automation to your home's existing electrical setup. It features two built-in smart relays, allowing you to control two separate devices independently through the Tapo app or voice commands via Siri, Alexa, and Google Assistant. Depending on your needs, you can set it to Switch Mode for managing lights, outlets, or electric floor heating, or use Roller Mode specifically for motorized shutters. Because it is Matter certified, this module integrates seamlessly across various platforms including Apple Home, Samsung SmartThings, and IFTTT. Measuring just 44.7 x 40.7 x 16.1 mm, the white module fits discreetly into indoor installations and supports a wide range of power inputs from AC 100-250V to various DC voltages. To ensure long-term reliability, it includes zero-crossing protection which significantly extends its lifespan, alongside safeguards against overloading, overheating, and relay failure. When used in Roller Mode, the device can detect obstacles to prevent damage to your shutters, while those using AC power can keep track of their electricity usage through integrated energy monitoring.
