Product Description

RELAY

INTRODUCTION:

  • Smart relay, can control electrical loads up to 5 amps at 120V (or control larger loads by using this relay to control other relays or contactors with sufficient voltage and current ratings)
  • The YoLink Relay is a smart, dry contact relay that can be controlled by your iOS and Android devices and by Alexa and Google Assistants, and 3rd-party IoT integration, such as IFTTT. The YoLink Relay can be used to make any non-smart low voltage or high voltage* device or equipment smart. Simply add the YoLink Relay to the YoLink app (YoLink Hub required, not included) and enjoy remote status display and control of your device/equipment, including on/off control, timers and schedules, from anywhere with an internet connection. In addition to voice control using Alexa or Google Assistants, the user-friendly YoLink app provides options for automated control of your devices, appliances, and equipment via automation (e.g. “If motion detected, activate 12V DC security siren”)
  • *If the Relay will control loads over 5 amps in current or 120VAC or 30VDC in voltage, a “dumb” load relay (with coil voltage and contact rang sized accordingly) must be installed. The Relay will control this dumb relay, which will control switching of low or high voltage to your equipment

FEATURES:

  • One normally-open dry set of contacts for control of electrical circuits or equipment/devices
  • Control-D2D Device-to-Device pairing allows for some functionality of devices even during the loss of WiFi, internet, and even power (battery-powered devices, only; this device is not battery-powered; requires a UPS or battery backed-up low-voltage power supply, for continued operation in power outages.

BENEFITS:

  • Works with the convenient and user-friendly YoLink app
  • Extremely easy and fast installation using the YoLink app with Scan & Play
  • Ready for manual control, automation ("if this, then that") and schedules

APPLICATIONS:

  • YoLink’s industry-leading long range communication allows for placing the relay in separate garage buildings, sheds, storage buildings, barns, greenhouses, etc.

integrate and automate

Requirements:

  • YoLink Hub with an internet connection (wired Ethernet or 2.4GHz Wi-Fi). Refer to the Hub user guide for additional information
  • Smartphone or tablet running iOS 9 or higher, Android 4.4 or higher
  • Existing or new home appliance or device with wiring ready
  • DC 5-24V power supply with wiring ready (Power adapter/supply NOT included)
  • Voltage tester, small slotted screwdriver, wire stripper/cutter or utility knife, or scissors
  • Double-sided mounting tape (3M brand heavy-duty recommended)

Features:

  • “YoLink” is a proprietary wireless technology provided by YoSmart, which is based on Semtech's LoRa wireless technology combined with the YoSmart smart home/building protocol, to provide the most advanced smart home/building devices solution. Compared to WIFI, Bluetooth, ZigBee, Z-Wave, and other smart home protocols, it has the advantages of low-power consumption, long-distance coverage (wall penetration), and anti-interference. It is the first smart building/home protocol that can be very easily set up and is a very low cost but creates a reliable, robust, and more secure IoT network.
  • YoLink Hub requires a 2.4 GHz Wi-Fi connection or a wired connection to your network equipment (patch cord included); We strongly recommend you use a wired connection to the network for a more stable network connection.
  • Here to Help: We strive to make the YoLink product experience as smooth as possible, and we are working every day to improve it, in our app and in our product documentation.

    Range from Device to Device is exactly as specified. Really incredible. Hub to device did not perform anywhere near the specified range. For me this wasn't a problem, as I'm using the relay to trigger a Zigbee button when a YoLink motion sensor is triggered. You could also attach a Zwave device or some other protocol. This gives a nice local, long-range D2D Yolink sensors, bridged to any other device protocol that responds to a contact closing

    Only product which I used can stop those scammers hacking. Plus it has long distance effect. I used it to control my sliding gate which is constantly disturbed by neighbours scammer's signal . Its low frequency has strong signal and won't be jammed.

    I use the water detection sensors hooked to to my well pump.
    Works very well and love the fact that the batteries last a few years.
    This will definitely save my house from water damage.
    I definitely recommend this product

    This little relay works like a charm and like all the Yolink devices I have, it takes only seconds to get it connected to the hub. I have it integrated into my older AI-PHONE gate comms system. Now I can open my gate from anywhere. Just love this little device!

    I bought two relays but only one works, the other will not pair to the hub no matter how many times or what I tried.

    I have not had this problem with the over 20 YoLink products I have in my home.

    This takes a 5v-24v DC input to power it. Keep that in mind. I had a transformer that I simply cut the barrel head off of and that worked great. If you don't have one, you need to buy one to power this device.

    This easily controls our outdoor flood lights. We programmed the system to respond to our key fobs for ease of use.

    This is a small device making possible to wire it up and tuck it inside of a 2x junction box along with the other wires, making it safe and protecting people from possible shock from the exposed connection screws.

    This is NOT waterproof in any way. It has no battery.. It is a decent value, but could be a little more affordable.

    --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 sensors
    6 x Indoor temp / humidity sensors
    1 x Outdoor temp / humidity sensor
    4 x Leak sensors
    1 x Standard hub

    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.

    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.

    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.
