Review: Versatile relay module - I use a lot of Shelly devices and this Shelly Pro 4PM relay module is just what I needed. I am using two of them together with Home Assistant to control 8 UFH zone actuators for the heating at home. I wanted Ethernet because wi-fi would not be rliable where they are located. My only negative comment would be that I am using them inside a small consumer unit and the depth of the modules is insufficient for the display to protrude through the slot in the way MCBs do. Functionally the modules are great!
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).
