Shelly Pro 3 | Wi-Fi & LAN, 3-Channel Smart Relay | Home & Facility Automation | Compatible with Alexa & Google Home | iOS Android App | Lights Automation | Controller for Motorized Valve

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! :)

I limit the charge current to 10 A 120v home wall outlet to not overload my wall circuit panel. I want to trickle charge my bank of lithium battery’s when the sun don’t shine. This device works well and easy to wire and setup. There is a very nice Shelly app to manually kick on the charge when I feel it’s needed. I can automate the process on a hourly basis or I can learn a bit of programming and logically kick on the charge if the battery’s get low.

This is a cool little relay! I used it to automate my pool controls (pump on, valve mode control and waterfall). Super simple to setup and set the time of day schedules. Its been working flawlessly.

These are great. easy to use. Easy to set up. I used mine to replace a swamp cooler controller. It was easy to do and to integrate with Home Assistant.

These shellys are a game changer when it comes to home automation. I use them to turn on and off my home theater subs when they are not in use and this Shelly has made it so easy to do it with its multiple connection types and easy to use api, anyone can do it!

I really like this product, and look forward to more like it, hopefully Shelly continues to deliver. My biggest gripe is really with respect to the terminal sizing on the unit, and the literature included; it's hard to know ahead of time that the terminals are smaller than what the average US customer might be used to in a residential setting, and these things are really not fit for larger romex conductors, and I've run into scenarios that were a little sketchy when clients jumpered in wire with less ampacity to fit the Shelly relay at hand. Aside from that I'm a fan, just do a deep dive with conductor sizes and ratings and cross against the products!

Hardware works. App is well-executed. It’s hard to find clean and functional software nowadays in this 🇨🇳 dominated market.

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.
