ShellyPro 2 | Wi-Fi & LAN, 2-Channel Smart Relay | Home & Facility Automation | Compatible with Alexa & Google Home | iOS Android App | Lights Automation | Controller for Motorized Valve

Perfect network relay, the app is very easy to use. You need to know a little bit of relay logic to connect to your application the instructions only show one diagram but you can connect on different ways.

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! :)

Got this to remote sequence an older Furman power sequencing system in our church. We control it over Bitfocus companion and it works great!

Works great. I have started moving ALL of my smart plugs to various types of Shelly Products because they work so well.

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've got dozens of Shelly devices running various things around two residences, and I'll only buy the Pro PM versions any more. They've got it all, Ethernet, front-panel switches, power monitoring, etc. A bit of Python code, and a Raspberry Pi can monitor and control any number of these things.I use them in one residence to control the HVAC splits based on the solar power system battery State Of Charge, so they can run 'constantly' over the summer when I'm not there, and I can come back to a house and (especially) closets that don't smell musty when you open them up.Pricey, yes, but all the features you could ever ask for![Don't use them for 16A loads, derate them about 50%]

I bought this to replace my pool timer. I use one side to turn on the pump and the other to turn on the Chlorine generator. WIFI connection works great. I turn off the breaker to backwash the pool, the pump and generator will start back up when I turn back on.

Pros:The Shelly 3 does what it's supposed to do - it works and successfully controls two different voltages simultaneously, which is exactly what I needed. Once it's set up and running, the device functions reliably.Cons:The instructions are beyond stupid. Seriously, whoever wrote the manual needs to go back to technical writing school. The setup process was unnecessarily frustrating because the documentation is unclear, poorly organized, and leaves out critical steps. I had to figure out most of the installation through trial and error and online forums.Bottom Line:The product itself is functional and does the job, but be prepared for a headache during installation. If you're not comfortable troubleshooting electronics or don't mind spending extra time deciphering terrible instructions, this might work for you. Otherwise, you might want to look for alternatives with better documentation.Would recommend only if you're tech-savvy enough to work around the awful manual.
