| Connectivity | not listed | LoRa wireless (1/4 mile range) |
| Smart home compatibility | not listed | Alexa, Google Assistant, IFTTT |
| Electrical load capacity | not listed | 5A at 120VAC or 30VDC resistive |
| Hub requirement | Functions as central hub | Requires YoLink Hub for app and cloud connectivity |
Which one should you choose?
Choose YoLink Smart Home Hub if
- You need the central controller to link YoLink devices to the internet.
- You plan to set up base infrastructure for future YoLink hardware.
Choose YoLink 5A Smart Relay Switch if
- You need dry contact switching for electrical loads up to 5 amps.
- You already have a YoLink Hub and need long-range LoRa hardware control.
Verdict: The YoLink Smart Home Hub suits you if you need central gateway connectivity for compatible hardware. The YoLink Smart Relay Switch suits you if you need to control power flow to AC or DC equipment. You must install the hub first because the switch cannot access app controls or voice integrations without it.
YoLink Hub vs Relay Switch Comparison
Primary Function
The YoLink Smart Home Hub (YS1603) serves as the central controller for your entire system. It connects devices to the internet and cloud services. Without it, the YoLink Smart Relay Switch (YS5706) cannot function with the app or support third-party integrations. The relay switch is an endpoint device. It uses dry contact output to control AC or DC equipment up to 5 amps. You need the hub to manage the switch remotely. One is the brain; the other is a muscle.
Connectivity Range
Both products rely on LoRa technology for wireless communication. This technology provides long-range coverage, up to a quarter mile. This range helps in areas challenging for Wi-Fi, such as basements, sheds, or remote outbuildings. The relay switch uses this connection to send data to the hub. The hub receives these signals and processes them. Both devices benefit from this low-power, long-distance link. You get reliable connectivity in difficult spots where standard Wi-Fi often fails. The range is a shared strength of the ecosystem.
Smart Home Compatibility
The YoLink Smart Relay Switch integrates with Alexa and Google Assistant. You can control it via voice commands or routines. It also supports IFTTT for advanced automations. The YoLink Smart Home Hub enables these integrations by connecting devices to the cloud. Without the hub, the switch does not work with voice assistants. The hub itself does not list direct voice control. It acts as the bridge. You need both for full smart home functionality. The switch offers the interface; the hub provides the connection.
Physical Build
The YoLink Smart Home Hub measures 4.33 by 4.33 inches with a height of 1.06 inches. It weighs 6.7 ounces. It comes in white. Variations include options with or without battery backup. The YoLink Smart Relay Switch has a different form factor. It is smaller, with a height of 0.67 inches. The width is 4.23 inches. The switch is designed for installation in electrical boxes. The hub is a standalone unit. The build styles reflect their different roles in the system. You place the hub centrally and the switch at the load.
Setup Process
The YoLink Smart Relay Switch features a scan-and-play setup. You do not need to type letters in the app. You can even scan after installation. This offers flexibility during the wiring process. The YoLink Smart Home Hub is required for this setup to work. It pairs with the switch. The hub connects to your network. You must have the hub to initialize the switch. The switch simplifies its own pairing, but the hub remains the essential first step for any YoLink device to become operational in your home.
Power Control
The YoLink Smart Relay Switch provides power flow control. It uses a dry contact output to manage AC or DC equipment. The maximum load is 5 amps at 120V AC or 30V DC for resistive loads. This allows you to control lights, fans, or other low-power devices. The YoLink Smart Home Hub does not handle power loads directly. It only sends commands. The switch is the component that actually interrupts or completes the circuit. You rely on the switch for the physical control of your connected equipment.
Which YoLink Model Fits Your Needs
First-time YoLink users needing a base station
You cannot use the relay switch without this hub. The YS1603 acts as the central controller, connecting your devices to the internet and cloud. It is the essential foundation for any YoLink system. Without it, the relay switch does not work with the app or support third-party integrations like Alexa or IFTTT.
Users automating high-power AC or DC equipment
This relay switch provides dry contact output for controlling AC or DC equipment up to 5 amps and 120VAC or 30VDC. It is designed for resistive loads. You can use it to manage lights, fans, or other devices that require a switch mechanism rather than a simple hub connection.
People installing devices in remote or outdoor areas
The relay switch uses LoRa technology for long-range connectivity. It offers a receiving range of up to a quarter mile. This coverage enables use in areas challenging for Wi-Fi, such as basements, sheds, or remote outbuildings. It ensures reliable control where standard smart home signals might fail.
Those wanting voice control for specific appliances
You can integrate this switch with Alexa and Google Assistant. By adding the YoLink skill, you can control devices by voice command. It supports routines and automations that include other third-party smart devices. This allows you to turn off lights or equipment hands-free through your preferred voice assistant.
