YoLink Smart Relay - YoLink Hub Required

  • $23.99
  • $29.99
Shipping calculated at checkout.



  • 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)



  • 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. See "Related Devices" for our battery-powered relay option)



  • 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



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



  • YoLink Hub with an internet connection (wired Ethernet or 2.4GHz Wi-Fi).
  • Smartphone or tablet running iOS 9 or higher, Android 4.4 or higher
  • Tools Required, Including But Not Limited to: Phillips screwdriver, slotted screwdriver, electrical tape, wire nuts, wire stripper tool, voltage multimeter or voltage tester tool
  • Installation Difficulty Level: Moderate Easy



  • Outdoor Siren Controller: this completely wireless smart controller is capable of controlling 12VDC loads up to up 400 mA (or capable of controlling 12VDC coil relays that have contacts rated for larger loads)


  • YoLink Hub is required. Starting your first YoLink system? Consider one of our kits
  • Your applications will vary, but any of our smart sensors, such as temperature/humidity sensors, for example to control heaters and dehumidifiers, are suggested. All YoLink devices are compatible with our Hubs.
