Great relay, easy to install with correct parts
Very easy to install once you have all the correct parts. After looking through some reddit threads, a Shelly employee recommended using 14 AWG wire for the relay, but my house uses 12 AWG wire basically everywhere. I used 14 AWG wire and some Wago clips to connect to the lead from the house and had no issues powering the relay. I installed this on an outlet to power a cheap wall mounted tablet with terrible battery management. The outlet now turns on and off to keep the tablet battery between 25% and 85% and has worked flawlessly. Getting the relay to go into Zigbee mode was a little more complicated than the instructions imply (I had to press the button harder than I thought, it felt like I was pressing hard enough but the relay wouldn't change radios), but once I had it in Zigbee mode, I was able to connect it to Home Assistant through Z2M with no issues. As a bonus, if you put this in Zigbee mode it will automatically act as a Zigbee repeater. I went back and forth between this and the mini for a long time, but the higher amperage rating for the 1PM Gen 4 is what pushed me over the edge. This is a great product, it installs very easily if you have the correct parts, it functions exactly as expected, and there is great support online from Shelly.

Best Company at making fun stuff that actually works
All Shelly devices are really cool, really small and so many options. The power meter function is fun to watch how much your hot water heater runs all day. I have them on all my switches (side by side with a switch, and controlled by said switch for backup).

Highly recommended for home automation applications
I highly recommend this. I needed a way to be able to remotely power cycle my furnace. This had all the features I was looking for: current rating, physical size, and remote accessibility. Lots of connection options and home automation opportunities.

Unlimited applications!!
The work as advertised. My electrical company of 51years is installing these for a national badge factory to remotely turn the hot glue machines on/off remotely, This is cutting company cost for them and they are extremely happy. Currently have 15 installed with no issues. they have only been online foe 3 months. It has saved 2hrs of labor down time per machine per day. You do the math

Diagrams suck!
Boy! The schematic and hookup diagrams are awful...Very non-conventional. Once they're decoded, the thing works as advertised.

Great Option to Make a Smart Outlet
This was the only 16-amp solution I could find. Works great as a Smart switch for an outlet. I had really wanted to use the Bluetooth gateway as well, but when I switched the unit to Zigbee, the Bluetooth gateway was gone. Since my Wi-Fi does not reach to where I installed it, Zigbee was my only option. It is, however, a nice Zigbee router to add to my network.

Not easy to set up once wired in.
Had trouble setting it up on the Shelly app but eventually got there. Works well so far after a couple of days. Read the miniture instrictions or AI on how to set up, matter is default, 5 quick presses of a small button switches between zigby and the more widly used matter. 10 seconds to put in bluetooth mode...

Shelly Mini PM Gen4 – Compatto, preciso e con una connettività davvero completa
Dopo l’ottimo acquisto del Shelly 1 Mini Gen4, ho deciso di provare anche questo modello Mini PM Gen4, e si è confermato un prodotto affidabile e tecnicamente molto avanzato. Le dimensioni ridotte lo rendono perfetto per installazioni in spazi stretti, senza rinunciare a funzioni evolute come il monitoraggio energetico. 🔌 Connettività completa: Wi‑Fi, Bluetooth, Zigbee e Matter Uno dei punti più interessanti di questo dispositivo è la multiprotocollo integrata, che permette di scegliere la tecnologia più adatta alla propria infrastruttura: Wi‑Fi → per integrazioni tradizionali e compatibilità universale Bluetooth → utile per configurazione rapida e provisioning Zigbee → ideale per reti mesh stabili e a basso consumo Matter → per massima interoperabilità con ecosistemi moderni (Alexa, Google, HomeKit) Questa flessibilità lo rende un modulo estremamente versatile, adatto sia a installazioni semplici sia a sistemi domotici complessi. ⚙️ Utilizzo con Zigbee2MQTT Nel mio caso è stato integrato tramite Zigbee2MQTT, dove viene riconosciuto correttamente e comunica in modo stabile. La risposta ai comandi è immediata e non ho riscontrato disconnessioni o ritardi. L’integrazione è pulita e permette di sfruttare tutte le funzioni del dispositivo senza configurazioni aggiuntive. 📊 Monitoraggio della potenza Il monitoraggio energetico è preciso e aggiornato con buona frequenza. Permette di visualizzare: Potenza istantanea Tensione Consumo totale Perfetto per automazioni avanzate o per analizzare i consumi reali di un elettrodomestico. 🔧 Installazione Il modulo richiede fase e neutro per l’alimentazione. È un aspetto da verificare prima dell’installazione, soprattutto negli impianti più datati dove il neutro non sempre è presente nelle cassette di derivazione. Il cablaggio è semplice e ben documentato, e la qualità dei morsetti è buona. 🧩 In sintesi Dimensioni ultra‑compatte Connettività Wi‑Fi / Bluetooth / Zigbee / Matter Perfetta integrazione con Zigbee2MQTT Monitoraggio potenza preciso e affidabile Comunicazione stabile e tempi di risposta rapidi Richiede fase + neutro Costruzione solida e progettazione curata 💬 Conclusione Un modulo smart completo, moderno e molto versatile. Grazie alla connettività multiprotocollo e al monitoraggio energetico integrato, è una soluzione ideale per chi vuole un dispositivo compatto ma professionale, perfettamente integrabile in qualsiasi ecosistema domotico. Un acquisto che conferma la qualità della nuova generazione Shelly.
