Control devices and monitors performance
Excellent product, simple to set up, network and use..: solid construction and quick delivery

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).

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!

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

Not bad, but not really pro level either
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.

Perfect for the home automation geek
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

Great Shelly product
I really like this little controller unit. I use it to control several contactors that supply in floor heat and water pre-heater circuits to turn them off during peak charge periods from the utility. The Shelly app and the system’s configurability are impressive. I’m looking forward to thinking up more advanced uses for their products.

Per home Assistant é perfetto!
Per l’uso che ne dovevo fare é assolutamente perfetto. Ho appena acquistato una casa nuova e mi sono trovato con i classici relè passo passo nel quadro elettrico per l’accensione delle luci (che è in camera quindi i click meccanici anche no). Inoltre avevo già un sacco di dispositivi zigbee tra cui le luci che gestivo tramite sensori a micro onda e home Assistant nella vecchia casa. Lo uso con gli input in modalità detached a cui ho collegato il ritorno dei pulsanti (legge la 220v quindi il pulsante va collegato come ci fosse il passo passo. Linea e ritorno) mentre le uscite sono sempre chiuse a cui ho collegato il ritorno delle lampadine che ho sostituito con delle aquara t2 in modalità zigbee e in alcune ho collegato la fase delle prese a cui sono collegati gli alimentatori dei led che a sua volta sono collegati a dei controller zigbee. Su home Assistant espone una valanga di eventi per i pulsanti il che è strabiliante per gestire scenari (pressione singola, doppio tocco, triplo tocco, pressione prolungata, pulsante su, pulsante giù). Infine mantiene anche la funzione di misurazione dei consumi dalle sue uscite. Collegato tramite lan é stato semplicissimo fare queste modifiche e aggiungerlo su HA che lo ha rilevato in autonomia. In sostanza ti riesci a creare una domotica completa per quanto riguarda gli input. Decidi quale pulsante deve fare cosa e sul dispositivo che vuoi togliendo anche di mezzo i click meccanici. (Possibilità di dimmerare le luci tramite pressione prolungata o cambiare scenario in base al doppio tocco o triplo ecc insomma le possibilità che ti da HA). Ovviamente L installazione richiede l intervento di un elettricista, per fortuna sono uno di essi e nel giro di mezz’ora ho eliminato i passo passo e collegato il dispositivo. Chiaramente dipende dall uso ma per quello che ho descritto è perfetto!
