VIVOSUN GrowHub Controller E25 for Grow Tent Cooling Ventilation Lighting, Supports Smart Grow System Devices, Easy to Install & Use, WiFi App Controllable, Expansion Port for E42A+/E42A/E42

This thing is kinda cool and does exactly what I wanted it to do. I’m using it to manage two grow lights and it keeps them running at a set level instead of blasting at full power all the time, which feels way more efficient from an electricity standpoint. Setup was easy, the app works fine, and once it’s configured I mostly forget it’s even there. It’s not overloaded with confusing options, but still gives you enough control to make a real difference. If you’re already using VIVOSUN gear and want smarter control without overthinking it, this is an easy 5 stars. I'll eventually buy other things to control, but for now, just a couple of lights.

My last ever vivosun product I ever have to buy. The grow light requires this to function but does not come with it. I don't mind their software, easy peasy. I wanted to try the lights with fans plugged in, the spectrum tuning is just silly but less fans sounds nice. Their other products just don't really compare for the price and functionality. They were the most disappointing clip fan out of the other brands I tried. This 5 star is my goodbye vivosun

Works well. I can now turn on and off my Vivosun 400w pro and adjust everything from the fans to light intensity. Well worth the money to control your products though your phone app.

I picked up the VIVOSUN GrowHub E25 to control my AeroLights for starting vegetable seedlings indoors, and overall, it’s been a great addition to my setup. While it’s clearly designed with a different audience in mind, it still offers solid functionality for anyone looking to automate their grow tent environment. Setup & Ease of Use Right out of the box, setup was painless. The E25 connected to my Android phone immediately, and getting it onto my WiFi network was just as simple. The VIVOSUN app was straightforward, and I didn’t run into any connection issues or troubleshooting headaches—something I really appreciate in a smart device. Functionality & Performance I’m using it to control four AeroLights that are linked together, and while this is my first time using artificial light for seedlings, I’m feeling optimistic. Last year, I learned the hard way that my windows don’t provide enough natural light, so I’m hoping this setup gives me stronger, healthier plants. The app itself is very responsive, and while I’ve only browsed the automation scheduling, it looks easy enough to set up. I like the idea of having light schedules tailored to different plant growth stages, but this leads to one of my biggest gripes… Missed Opportunity for Vegetable Growers VIVOSUN’s app is clearly designed with cannabis growers in mind, which is fine—but for those of us growing vegetables, it feels like an afterthought. The default pictures of marijuana plants in the app feel out of place when I’m just trying to start tomatoes and peppers. It would be fantastic if VIVOSUN included grow recipes for common garden vegetables instead of just cannabis. Even better, if they allowed customizable grow schedules with user-uploaded images, that would make it much more versatile. Build Quality & Reliability So far, no glitches or disconnects—the connection has been rock-solid. One concern I do have is the physical design of the dongle—it sticks out a bit, and I worry about accidentally snagging it and damaging the port on the AeroLight. A right-angle or recessed connection would have been a better design choice. Pros & Cons ✅ What I Like: ✔ Super easy setup – No headaches getting it connected ✔ App is very responsive – No lag when controlling lights ✔ Controls multiple AeroLights at once – Great for my grow setup ✔ Works well for all experience levels – Beginner-friendly but powerful ✔ Reliable connection – No disconnections or weird glitches so far ❌ What Could Be Better: ✖ App is too cannabis-focused – Needs grow recipes & images for veggies ✖ Dongle design – Could be more secure to prevent accidental damage ✖ No Home Assistant integration – Would love to control it alongside other smart devices Final Thoughts – A Solid Controller with Room to Grow The VIVOSUN GrowHub E25 is a great tool for automating grow lights, and it works seamlessly for my vegetable seedlings. The easy setup, reliable app, and good automation features make it a strong choice for growers of all levels. That said, VIVOSUN could really improve this product by making it more inclusive for vegetable growers and adding Home Assistant integration. If you’re looking for a simple way to control and automate your grow lights, this is a solid pick—just be prepared to ignore all the cannabis imagery if you're growing veggies! ⭐ 4 out of 5 stars – Would be 5 stars if it had more customization for non-cannabis growers.

Say goodbye to all the cords

High jacks the light and stops it from working. Very hacky implementation. Not compatible with external timers. Resets when power is cut. Connectivity inconsistent. Just bad waste of money. One star.

I can turn my grow fans on or off and adjust the speed from literally anywhere. Fantastic to have for the money

Full disclosure, I'm 100% aboard the Vivosun train! I have 10 or 12 Vivosun products, SGS and standalone and they are all awesome. I have two large grow tents and we produce all year long. However, before we had large tents we had medium and small. So because we had bumper crops all summer, I actually started a third tent and I had a Vivosun Fan and Light... enter the GrowHub E25. For like $20, I added it right to my APP and had another garden, fully automated and running any recipe you can imagine. I'm writing this review because I got a reminder while buying another one. E25 took 3 minutes to add and configure and it's Vivosun, so it starts up right into a superior management App. Don't waste too much time thinking about it - it's a winner! Love What You Grow!

Prima

Awesome Way to control the Vivosun fan and light. Bought 3 of them

Einfach Cool. Keine Kabel im Zelt verlegen

I use the app to control how bright I want it and how fast is the fan should work and I have two controllers hooked up since I have two lights

Alles Top! gerne wieder! DANKE!!!
