Review: Great device! Solid app to control it! - 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.
Review: Excellent Relay For Integrating Large Tools Into Home Assistant - I picked up this relay to control a big dust collector and air compressor remotely in my shop, using a 120v contactor. Setup was straightforward—the included instructions and online guides were actually useful, even for someone who isn’t deep into home automation. I integrated the relay into Home Assistant, but I appreciate that you can program the unit through the Shelly App and all the configuration is stored locally and works even if it looses connection to the internet. Build quality is solid, and both the Wi-Fi and LAN options are handy. The two independent channels are a real plus for running more than one machine. Built-in power monitoring is a nice touch, letting you see energy use at a glance.

This is the largest size that supports dry contacts. Was able to add it to the Shelly app very easily.
