Technical specifications for the Lesim Smart WiFi Light Switch indicate a TYWE3S ESP8266-based module providing 2.4GHz connectivity. Material analysis confirms a V0 flame-retardant PC housing paired with a scratch-resistant tempered glass faceplate. The mechanical relay is rated for a maximum of 10A or 1250W, making it suitable for standard lighting loads but unsuitable for high-wattage inductive appliances. A neutral wire is mandatory for the installation of this hardware.
Forensic audits of the software stack have identified a pattern of "zombie states" where the Wi-Fi module may become unresponsive while the physical toggle remains operational. This is often corrected by a manual power cycle. The 2.4GHz-only radio is susceptible to electromagnetic interference in dense RF environments. The capacitive touch interface provides no tactile feedback, relying entirely on visual or audible cues from the relay for confirmation of state change.
The device is compatible with global voltages ranging from AC 100V to 240V. While it integrates with the Tuya/Smart Life cloud ecosystem, it lacks native support for 5GHz networks or emerging Matter/Thread standards.
If tactile feedback is a requirement for your installation, the Smilewolf M5 Smart Wall Switch provides physical push-buttons within the same Tuya ecosystem. This unit is classified under smart wall switches for comparative technical review.
