Why do I need a YoLink Speaker Hub?
The Speaker Hub acts as the central gateway for YoLink devices, which use LoRa wireless technology (not Wi‑Fi) for extreme range (up to 1/4 mile outdoors) and obstacle penetration. It connects devices to the internet, cloud services, and third‑party integrations like Google Home.
Is the Hub compatible with all YoLink devices?
Yes, the YS1604-UC Speaker Hub works with all YoLink UC‑model (US server) devices except the YS3603‑UC Remote. Older hubs (e.g., YS1603‑UC) remain compatible and can be used alongside the Speaker Hub for redundancy.
Can I use multiple hubs?
Yes! Multiple hubs improve reliability and coverage. If one hub goes offline, devices automatically connect to another. This is ideal for large properties or multi‑storey buildings.
Does the Hub work globally?
YoLink devices function worldwide with internet access, but regional models (UC for US/Canada, EC for UK/Europe) cannot mix due to differing certifications and encryption policies.
How is the Hub powered?
The Hub requires a 5V/1A power supply (included) and operates at 100–240V. It has no built‑in battery, but you can use a UPS (Uninterruptible Power Supply) for backup during outages.
Does the Hub support 5GHz Wi‑Fi?
No—it only connects to 2.4GHz Wi‑Fi networks. For mesh systems, temporarily disable the 5GHz band during setup.
Can I use cellular data or public Wi‑Fi?
Cellular hotspots work, but public Wi‑Fi (e.g., hotels) with multi‑step authentication is not supported.
What if my internet goes down?
The Hub relies on cloud connectivity. Without internet, app controls and automations won’t work, but Device‑to‑Device (D2D) pairings (e.g., sensor‑to‑siren) function locally.
How many devices can one Hub support?
A single Hub handles 200+ devices in real‑world tests. For large setups (100–200 devices), add a second Hub for stability and adding additional YoLink devices
What’s the communication range?
Up to 1/4 mile (1,320 feet) in open air, though walls and metal reduce this. Extend coverage by placing multiple Hubs strategically.
How much data does the Hub use?
Minimal—a 2Mb/s internet connection suffices. Data usage is optimised for low bandwidth.
Why won’t my Hub connect to Wi‑Fi?
Ensure you’re using a 2.4GHz network.
Check the power adapter and USB cable (avoid extensions).
Temporarily disable router firewalls or enable ports 8001–8002 (TCP) for us.yosmart.com and api.yosmart.com.
How do I set up offline notifications?
In the YoLink app:
Go to Settings > Alarm Strategies > Create New Strategy.
Select your Hub, enable notifications, and test by unplugging it for 5 minutes.
Can I reboot the Hub remotely?
Yes! Use a YoLink smart plug with automation: trigger a power cycle (off + delayed on).
Does the Hub support local automations?
No—automations require cloud connectivity. However, Device‑to‑Device (D2D) pairings (e.g., leak sensor to valve controller) work offline.
How secure is the system?
YoLink uses AWS encryption, dynamic device‑specific keys, and regular security audits. Data is doubly encrypted during transmission.
Does the Hub work with Google Home?
Yes! Integrate via the YoLink app, but only devices (not the Hub itself) appear in Google Home.
Can the hub be powered by a battery
Yes. The hub requires 5V 1Amp from a power source. Most modern portable batteries \ power banks can support this. Depending on use the a 10,000 mAh bank would offer up to 10 hours of runtime.
