VIVOSUN GrowHub E25 Controller - Compact Hub for Your Smart Grow System
Best for: Growers already using VIVOSUN Smart Grow System devices who want app control and grow recipes without buying a full-size controller.
Our thoughts
This is the entry point into VIVOSUN's connected ecosystem rather than a standalone controller in its own right - it plugs straight into a compatible light or fan and gives you app control from there. Simple to set up, and it doubles as an expansion port if you later add a full GrowHub E42/E42A, so it's not a dead end if your setup grows. One we sell a lot of for new growers dipping a toe into smart control for the first time.
The VIVOSUN GrowHub E25 is a small, plug-and-play controller that connects directly into the Type-C port of a compatible VIVOSUN Smart Grow System (SGS) device, such as an AeroLight light or AeroWave E fan, turning it into a WiFi-connected, app-controllable unit. It can run standalone this way, managing up to 8 lights on its own, or work as an expansion port for the larger GrowHub E42/E42A controller, letting the two share a single schedule as you add more lights to the system.
Setup is deliberately simple: plug it into the SGS device's Type-C port, press the single button to configure WiFi, and it's ready to control through the VIVOSUN app. From there you can set lighting and fan schedules, run pre-built grow recipes tailored to different plant stages, or use auto-modes that adjust output automatically as your grow progresses - all without needing to touch a full environmental controller.
How it compares
The E25 sits below full environmental controllers like AC Infinity's Controller series, positioned as a lightweight entry point rather than a competitor to them directly.
- Far cheaper than a full smart controller like the GrowHub E42A or AC Infinity's Controller 69, since it adds WiFi/app control to connected lights rather than managing sensors and multiple device types
- Simpler setup than a full controller - one button and a Type-C connection versus configuring lights, fans, and sensor triggers
- Doubles as an expansion port for the E42/E42A, so it's not wasted if you scale up later, unlike most basic WiFi dongles which get replaced outright
You're not getting environmental sensors or fan automation at this price - you're getting app control for your lights and a growth path if you want more later.
Usage guidance
Getting the most from the E25 depends on how it's set up and paired.
Standalone setup
Plug directly into the Type-C port on a compatible SGS device, hold the WiFi button to connect it to your network, then add the device in the VIVOSUN app to start scheduling.
Expanding with GrowHub E42/E42A
If you already run or plan to add an E42/E42A, connect the E25 via RJ45 cable to link additional lights into the same schedule rather than running them on a separate system.
Using grow recipes
Select a pre-built recipe in the app matched to your plant's current stage rather than manually setting schedules from scratch - useful if you're new to lighting schedules.
Multiple lights
Link additional AeroLight units via RJ45 if you need to cover more than one fixture from a single E25 setup.
Technical specifications
- Connection: Type-C port on compatible SGS device
- Connectivity: WiFi via VIVOSUN app
- Standalone light capacity: up to 8 lights
- Use with E42/E42A: links via RJ45 to share a single schedule with the main controller
- Compatible devices: AeroLight, AeroWave E, other SGS-compatible units
- Setup: one-button WiFi configuration
- Use modes: standalone controller or expansion port
Who this is for
- New growers wanting app control on a single light or fan without a full controller purchase
- Existing GrowHub E42/E42A users wanting to link extra lights into the same schedule
- Budget-conscious growers who don't need environmental monitoring, just remote scheduling
- Anyone building out a VIVOSUN Smart Grow System setup piece by piece
Best suited to single-device smart control now, with the option to scale into a full controller setup later.
Our take
This is a sensible low-cost way into app-controlled growing without committing to a full environmental controller you might not need yet. It does one job cleanly and leaves the door open to expand later rather than becoming redundant kit.
Worth picking up if you want your first taste of smart control at a price that makes sense.
