Shelly Pro 4PM - Wi-Fi 4-Channel Smart Relay With Power Metering, Max 40A, Home Automation, Compatible with Alexa & Google Home, iOS Android App, No Hub Required, Remote Control and Monitoring

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).

good device, been running it for a month prometheus exporter does not seem to work on this gen2 device

But extremely good at power monitoring and Wi-Fi control

Faulty out of box! Screw for for output terminal has been installed upside down . Clearly no quality control

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.

Great product, we have four in our control cabinet and use it to get a good understanding how much electricity we are using and where in much more detail than before. Which is nice because it help us reduce a significant amount and gave us good insights how many battery power (off grid home) we need to become fully self sufficient. + trustworthy and very detailed + doesn’t require cloud + easy to install for home assistance

eficaz

Its easy to instal land configure, and. The function is exactly as predicted

Buen controlador y fácil de prgramar

Ho acquistato il Shelly Pro 4PM per installarlo nel quadro elettrico e sono davvero entusiasta delle sue prestazioni. L'installazione è stata semplice e intuitiva, anche per chi non è un esperto. Grazie alla sua integrazione con Alexa, posso gestire l'accensione e lo spegnimento programmato di pompe tramite routine, e il dispositivo non perde mai un colpo! La precisione nella misurazione dei consumi per ogni canale è un grande valore aggiunto, aiutandomi a monitorare l'energia utilizzata in modo dettagliato. La costruzione è solida e il dispositivo funziona in modo impeccabile, offrendo un controllo completo e affidabile su più circuiti. Consiglio questo prodotto a chiunque voglia una soluzione professionale per la gestione domotica e il monitoraggio energetico.
