WFSMB works with TUYA – a smartphone app. It is used as a sensor for moveable objects such as doors, windows etc. It sends a notification to the smartphone. It could also be used for different lighting settings (like switching on/off WI-FI SMART lighting, sockets and switches that supply different type of electrical consumers). With the WI-FI SMART products one can develop an intelligent system operated via smartphone (tablet) or voice assistant.
