Shelly Pro 4PM | Wi-Fi & LAN, 4-Channel Smart Relay with Power Metering | Home Automation | Compatible with Alexa & Google Home | iOS Android App| Remote Appliances Control and Monitoring

These controllers are the best. They are simple to setup and work fantastically with Home Assistant. I have automated every single light with three of them.

Easy to install.. add to home assistant...easy to configure. Awesome shelly product

Very cool unit. I'm using it to control the lighting in my farm shop, the lights on the exterior of the shop, and also to trigger my electric door strike for the walk-through door and its programmed to turn the lights on if they're not already on. The coolest part is I have the fourth channel controlling a 60 amp contact closure relay to send power to my fuel barrels in my farm yard. This way no one can steal fuel All I have to do is open the app press the button and I have it programmed to shut off after 30 minutes. It works so slick! I really wish the unit had normally closed and/or dry contacts. Every output controls an additional relay because I'm either controlling 220 volts or the amperage exceeds the rating of the contacts. So the wattage function of the unit is useless in my situation. Outside of that, it works every time. I've since bought another one I'm going to wire it up to control my three-button overhead commercial door. The app to control this is very solid. If you're not patient or tech-minded you're going to struggle with this unit but stick with it and you'll get it. I'm completely hooked on these Shelly devices. I'm thinking of other ways I can use them like a timer to turn off my battery chargers for my Milwaukee tools so they don't blow up overnight. Currently wiring up exterior lights of my home on timers within the Shelly. My wife just rolls her eyes but I'm having fun! :) UPDATE: I've currently added another pro4 for more control over lights and I've added a pro 3 to control a commercial overhead door with a three-button open/ close /stop control. Each relay on the pro 3 performs the open/ close/ or stop function With an external relay for the stop circuit requiring continuous normally closed contacts. If I get around to it I'll post a picture of the wiring schematic.

I give 4 starts because 3 starts are not for a good quality product; seems it works as intended, I have installed it but unfortunately, I noticed that Neutral and Switch ports are very small compared to Outputs ports, so it hard on standardize wire gauge across the device, For Output ports, I was able on installing ferrules, but at the Neutral and Switch ports don’t, It may sounds as risky on electrical installations, At this time, critical equipments are managed and monitored via WiFi, I would redesign the device by removing ethernet port to make Neutral and Switch port bigger, I’ll think twice on rebuying the same device again, I may decide on buying contactors instead.

I use one of these for each of my laser cutters. One output for the laser, one to the chiller and one to my exhaust fan. Super easy to set up with the Shelly app and then pull into home assistant. From home assistant it’s a walk in the park to then automate each relay output.

Does what it says on the "tin"! No complaints so far. Works with Home Assistant quite well too!

The Shelly Pro 4 feels cheaply made, not sure why it's marketed so high, given that it's made in china. Also, the Shelly Pro 4 can't handle a dual load circuit, which is common in 240v powered pool pumps. Your best bet is to order a Tongou TOVMT 2P 16A, which can handle a dual load circuit of 240v.

The 4PM is used in my attic, managing the attic, bathroom, dryer fans, lights, and environmental sensors. I am using it to see if running the various fans is cost-effective and if the attic fan has any effect on the temperature in the house and the cost of cooling or heating. It was easy to set up and configure; it was quickly discovered by my home automation solution. Din rail makes it easy to put in an enclosure.

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

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.

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).
