VIVOSUN 2-in-1 Type-C Splitter — Smart Controller Port Expander for SGS Fans
Best for: Growers scaling their VIVOSUN setup from one fan to two without buying a second controller
Our thoughts
If you've got a GrowHub E42A and want to add a second AeroWave fan without the headache of daisy-chaining cables across your tent, this does the job properly. Solid bit of kit, built to last, and it actually solves the problem it's designed for.
The VIVOSUN 2-in-1 Type-C Splitter is a daisy-chain adapter dongle that turns one Type-C port on your GrowHub E42A controller into two, letting you connect multiple SGS devices without running cables all over your grow tent. It's a simple plug-and-play solution for anyone who started with one AeroWave E6 clip fan or AeroZesh inline duct fan and now wants to add a second without the clutter or expense of a second controller.
How it compares
This sits in the entry-level smart controller expansion category.
- VIVOSUN splitter: 2-port capacity, ecosystem-locked to SGS devices, simpler daisy-chain setup
- AC Infinity UIS Splitter Hub: 4-port capacity, multi-tier expansion, broader UIS device compatibility — but more complex and higher cost
- Both solve the same problem: scaling fan control without buying another controller
In plain terms, if you're running VIVOSUN kit and want to keep things tidy and straightforward, this is the right tool. If you're planning to control four devices simultaneously across multiple zones, AC Infinity has more grunt — but you'll pay for it.
Usage guidance
The splitter works in one main scenario, and it does it well:
Adding a second fan to your GrowHub E42A
Plug the splitter into your controller's Type-C port, then connect your first fan to one female port and your second fan to the other. Both run from the same port, respond to the same app commands, and keep your cable runs neat. No additional software needed — just connect and it works.
Cable management benefits
Instead of running two long cables all the way back to the controller, you can split the connection closer to your fans, keeping your tent organised and free of trip hazards.
System limits
One GrowHub E42A can handle up to 4 SGS devices daisy-chained using multiple splitters. So you could theoretically add another splitter to the second port of this one and connect four fans total — but realistically, two is where most growers stop.

Who this is for
- VIVOSUN GrowHub E42A owners wanting to add a second fan without buying another controller
- Growers scaling from single-fan setups to multi-fan configurations
- Anyone who values tidy cable management and wants to keep tent clutter to a minimum

- Budget-conscious growers who want to expand without doubling costs
Not suitable for non-VIVOSUN ecosystems or for anyone who needs to control more than two devices simultaneously from one port.
Our take
This is solid kit that does exactly what it's supposed to do. It's built well, solves a real problem (expanding your controller without buying another), and keeps your tent from looking like a cable salad. The nylon braided construction means it'll handle the wear and tear of a real growing space.
If you've already got a GrowHub and an AeroWave fan, and you're thinking about adding a second one, this is worth picking up. Good time to buy while we've got stock — it's the kind of accessory you'll end up replacing if you don't grab it now.
