Overall review
The Sonoff products are reasonably priced, the philosophy approach gives user options for DIY projects but also seamless straight deployment and installation. Control app has limited options for automation also also does not log the history from the SNZB-02 temperature / humidity sensors. The documentation is sometimes lower quality and basic info harder to find. Some WIFI/ZigBee control unit for CCT LED stripes / RGB LED stripes would be nice one.
