Review: Control devices and monitors performance - Excellent product, simple to set up, network and use..: solid construction and quick delivery
Review: Capable, well made and works - I’ve used plenty of Shelly devices in the past, and was eagerly awaiting the launch of the 4Pro. Although the screw terminals could be slightly higher quality, there’s nothing wrong with them and they function well. The device is plastic construction and appears well made. Once in the consumer unit, the display looks great and the buttons operate as expected. Pay attention to the wiring guide first, though, as the Shelly doesn’t ‘common’ any of the feeds: each channel effectively requires a dedicated L and N feed (no PE).
