Who it fits
Good fit for
You should choose this relay switch if you need to control high-power AC or DC equipment in locations far from your main router. The long LoRa range is ideal for outbuildings, sheds, or basements where Wi-Fi is unreliable. It is also a good fit for users who want to integrate third-party smart devices into Alexa or Google routines. If you need a simple, robust switch for non-lighting loads like pumps or fans, this 5A capacity handles common residential tasks effectively.
Who should skip it
Skip this product if you do not already own a YoLink Hub. The switch does not work without the hub, which is not included in the box. You cannot use it with the YoLink app or third-party integrations without it. Also, avoid this if you need a dimmer or a standard wall switch replacement that includes a neutral wire connection. This is a relay module, not a complete dimmer or no-neutral switch. Check the variations to ensure you select the correct type for your specific wiring setup.
Verdict: The YoLink 5A Smart Relay Switch offers reliable long-range control for non-lighting loads in hard-to-reach areas. It requires a separate hub but delivers solid integration with major voice assistants.
YoLink Smart Relay Switch Key Specs
Connectivity: LoRa
LoRa is a long-range wireless protocol that uses low power to transmit data over distances up to a quarter mile. This allows the switch to connect reliably in areas where standard Wi-Fi signals fail, such as basements, sheds, or detached garages. You benefit from stable control without needing to extend your home network. When shopping for smart home controls, compare this range against typical Wi-Fi or Zigbee devices that often struggle with distance or physical obstructions.
Power Flow Control: 5A, 120VAC/30VDC
This rating indicates the maximum electrical load the switch can handle, specifically 5 amps at 120 volts AC or 30 volts DC. It uses dry contact output to control AC or DC equipment. You must ensure your connected device does not exceed these limits to avoid damage. When selecting smart home controls, check the amperage rating against your appliance requirements. Higher wattage devices like heavy motors may require a different switch with a higher capacity rating.
Smart Home Compatibility: Alexa, Google Assistant, IFTTT
The switch integrates with Amazon Alexa, Google Assistant, and IFTTT for voice control and automation routines. You can use voice commands to toggle the switch or include it in complex automations with other third-party devices. This compatibility expands your smart home ecosystem beyond a single app. When comparing smart home controls, verify support for your existing voice assistants. Broad compatibility ensures you can control the device alongside other smart products in your home.
Setup: Scan and Play
The device supports a scan-and-play setup process, eliminating the need to manually type network credentials or device names. You can scan the device using the app before or after physical installation, offering flexibility during deployment. This simplifies the initial configuration compared to switches requiring complex pairing codes. When evaluating smart home controls, look for this feature if you want a hassle-free installation. It reduces setup errors and speeds up the process for multiple devices.
Design and build overview
According to the listing, the YoLink 5A Smart Relay Switch (YS5706-UC) is part of a larger ecosystem that relies on LoRa technology. This wireless protocol allows the device to maintain connectivity over distances up to a quarter mile. This range makes it suitable for locations where standard Wi-Fi signals are weak or unavailable, such as basements, sheds, or detached garages. The design prioritizes reliable long-range communication over local network dependency.
The product is available in six variations, including options for dimmer switches, fob switches, and no-neutral switches, alongside the 5A relay and a 15A relay version. You can purchase the unit individually or in sets of two. The listing provides specific dimensions for the device, measuring 4.23 inches in height and 0.67 inches in depth. These physical specifications suggest a compact form factor designed for standard electrical box installations. The specific materials, weight, and finish details are not listed in the provided data, so you must rely on the manufacturer's general description for those attributes.
A critical aspect of the design is its dependency on the YoLink Hub. The switch does not operate independently; it requires the hub to connect to the internet and support third-party integrations with Alexa, Google Assistant, and IFTTT. The hub is not included with the switch. This central controller requirement influences how you plan your smart home layout, as you must ensure the hub is within range to maintain the system's functionality. The setup process is described as simple, involving a scan-and-play method that eliminates the need for manual typing during installation.
Setup and everyday use guide
You must pair this switch with the YoLink Hub to enable any smart functionality. The hub acts as the central controller, connecting the device to the internet and the cloud. Without the hub, the switch does not work with the YoLink app. It also cannot support third-party integrations with Alexa or IFTTT. The hub is not included in the box. You can find it by searching for B07TQLKQLJ or purchasing the Smart Home Starter kit B07V246GCX. Setup is designed to be simple. The listing describes a scan-and-play process. You do not need to type any letters into your app. You can scan the device before installation or after. This flexibility allows you to install the hardware first and then configure the software connection. Daily use relies on the LoRa wireless range. The system supports distances up to a quarter mile. This makes it suitable for areas with weak Wi-Fi, such as basements or detached garages. You can control the switch via voice commands using Alexa or Google Assistant. You must add the YoLink skill to your voice assistant account. The switch outputs a dry contact signal. It can control AC or DC equipment with a maximum load of 5 amps at 120VAC or 30VDC. This resistive load limit applies to connected devices. You can also include the switch in routines or automations. These routines can involve other third-party smart devices integrated with your voice assistant. The process is strictly digital and remote. You do not interact with the hardware physically to change settings. The app handles all configuration. The switch responds to your commands through the LoRa network and the hub. This setup ensures reliable operation in locations where standard Wi-Fi signals are weak or unavailable.
Before you buy this relay
You must pair this switch with the YoLink Hub to enable any smart functionality. The hub acts as the central controller, connecting the device to the internet and the cloud. Without the hub, the switch does not work with the YoLink app and does not support third-party integration with Alexa or IFTTT. You need to purchase the hub separately. Check your existing smart home setup. This relay switch works with Alexa and Google Assistant for voice control. It also supports IFTTT routines. The dry contact output handles AC or DC equipment up to five amps. Ensure your connected devices stay within this limit. Installation allows scanning after placement, which offers flexibility. This device fits well in areas with weak Wi-Fi, like basements or sheds. It complements other smart controls by extending reach where standard protocols fail. Verify your wiring matches the dry contact requirement before buying.
Check before you buy
- Buy the YoLink Hub separately to enable app and voice control.
- Confirm your device draws no more than five amps at 120VAC or 30VDC.
- Check if your home has weak Wi-Fi in the installation area.
- Verify compatibility with Alexa, Google Assistant, or IFTTT for your routines.
