Shelly Pro 1PM - Wi-Fi Bluetooth Smart Relay Switch With Power Metering, Home Automation, Alexa & Google Home Compatible, iOS Android App, No Hub Required, Wireless Light Control

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!

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).

More of this Shelly stuff - awesome automation.I use this one for outside of my home lighting control.Has automatic dawn/dusk control - turn all lights out in day time.Use wifi PIRs to turn the right lights on outside.Siri, Alexa etc can be used, even without IFTTT.

But extremely good at power monitoring and Wi-Fi control

The media could not be loaded. good device, been running it for a monthprometheus exporter does not seem to work on this gen2 device

Nice for use with a little consumer unit on the side that’s already protected by its own RCD. Sort of plasticky, and the back comes off very easily. Probably a better solution than having small Shellys mounted inside a CU, but not a groundbreaking product.
