ENER-J Smart WiFi 4CH Switch Module, Converts Existing Switch to App & Voice Control, Works with Alexa & Google Assistant

Bring smart control to an existing lighting setup with the ENER-J Smart WiFi 4CH Switch Module, a compact switch module that works with current wall switches rather than replacing them. Its ultra-mini 39 x 39 x 19 mm format fits 98% of standard switch boxes, making it a practical option for homes, offices and rental properties where the original switch style needs to stay in place.

Remote control is available through the Smart Life or Tuya app, while Alexa and Google Assistant support adds voice operation. The module also supports dual-way control for traditional two-way switches without rewiring. Everyday functions include memory after power loss, along with timer, schedule and countdown settings. Family sharing and group control are included, with custom scenarios such as sleep mode, dinner mode and back-home mode.
