YoLinkRelay, Smart Switch, YoLink 1/4 Mile Super Long Range Smart Relay Compatible with Alexa, Google, and IFTTT, Max. 5 amps - Hub Required

--Update Feb 2024--I have become reliant on this device. Setup is still working great and we have total control over our pellet stove wirelessly. I have added another to control the lights on our solar shed, works wonderfully. The base station is about 300 feet away in the basement and in a closet and I don't have connectivity issues ever.--Original--I bought this for a project to install 12v lights on my shed, but I realized it would be perfect to control our Harman P43 pellet stove that I was planning on wiring to a millivolt thermostat.This turned out to be a better option. I split the negative wire on the room sensor probe and routed it through the relay portion. The controller pulls power from a 12v 12ah powerwheels batter (will swap this out for an 120v AC to 5v adapter later). When the relay is off the stove turns off with it and when the relay is on it automatically reignites in room sensor mode.I already have YoLink temperature / humidity sensors all over the house, so it was easy enough to create an automation in the app that toggles the relay on for three hours after the living room temperature sensor sends a low temperature alert (set for 64F).I was skeptical when I first purchased a YoLink product (I bought the water leak sensors + hub first), but I am a firm supporter of this brand now. Every single product I have bought from them has integrated easily and worked flawlessly.I currently have:1 x Relay (soon to be more)3 x Door/window sensors6 x Indoor temp / humidity sensors1 x Outdoor temp / humidity sensor4 x Leak sensors1 x Standard hub

I now use a number of YOLINK's devices and am very pleased overall. I have a forty-acre property and use the relay to trigger an input in my 1980's Westec W5000 security system. I also use the driveway sensor and the magnetic contacts as well. It has allowed me to blend older technology with modern so that I can get remote reporting via Starlink. I use other smart devices and well. I am a retired Master Service Technician from Westec (now defunct) and I took a trip down memory lane to install a sophisticated security system. I am proud and happy with the results.

This little device saved me over $75! I recently installed a Mighty Mule opener on the main gate to my property and wanted the ability to open it from my phone. Mighty Mule wanted over $100 for their wifi kit, and this little box was only $25 on sale. I found a spot inside the Mighty Mule control box to stick the relay and wired it up. Since I already had a YoLink hub, I didn't need to buy anything else. And if you don't believe the range claims, you should. My gate is over 350 feet away from my hub, which is inside my house, and this thing has 100% reliability so far when I need to open the gate. I have more issues getting a signal on my phone than I have with actually opening the gate once I'm logged in to the app!If you have a large property, YoLink is THE way to go for home automation. Affordable modules, easy installation, and SUPER long range.

Great new product by YoLink. I used it in place of a timer for our automated chicken coop door. I easily just moved the 4 wires over from the timer to this relay. It was super easy to setup a schedule too! It also appears to have a timer function. BTW, don't be shocked when you open the package, this unit is tiny!Lots of cool uses for this unit. It is a 5amp relay but if you could power something with more current if you used it to control another relay.. much like I'm doing with our coop door.I do have 2 minor issues. 1) It only uses double-sided sticky tape to affix it. Would have been nice to have a way to use a screw to hold it in place. If you ever have to remove it, it will require you to put on new tape. 2) Because this is in our chicken coop, which has metal walls and our hub is in our shop, which also has metal walls, there is a bit of a range issue. I'm sure the walls are making it a challenge. I just moved my hub to a different place in my shop and is working fine, still passing through 2 walls.

YoLink devices are of excellent quality, but what really counts is the service offered by the YoSmart company. I am responsible for many YoLink devices for numerous people; so I end up dealing with all sorts of issues, and YoSmart service is always there to help.

I purchased this device to use as a garage door opener, momentary contact switch, along with an outdoor grade sensor to tell me when the door is open. The device has a user programmable automation feature that I can tell the device to turn itself off making it a momentary contact switch. Sometimes the switch does not turn itself off. I do believe it's because I have double tapped to the device a couple of times when it didn't seem to be operating which would turn it back on. But in that case it does not always recognize itself being on and turn off as it is programmed to do. Still works well for the purpose intended. There is a function specific device, garage door opener and door position sensor, of this type available from the vendor which I may replace this one with and use this one as automation in some other purpose.
