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

Works great on a 2.4gig network

Does it’s best to maintain temperature and humidity levels in my grow tent. Haven’t had any issues. Easy to install and hook up.

Awesome controller. A must have for the lights.

Worked as expected

I purchased the VIVOSUN lights with a fan and these remotes allow me to get the lights exactly for the current phase of my plant growth and light intensity. Love them and once I make room for a grow tent I will be buying a few more ☺️

Useless product and app. App needs to be running on your phone to control the AeroWave E6 via the GrowHub E25... There is no point to buying the E25 for the E6 fan if it doesn't actually automate anything. Fan will turn ON for 50 minutes then turn OFF for what is supposed to be 10 minutes but it just stays OFF unless you run the app. Worthless and pointless.

BEWARE - the picture on this ad is false. I've notified the company. This unit does NOT have the ability to show Temperature and Humidity in the Vivosun App. You have to purchase an "AeroLab THB1S Bluetooth Hygrometer Thermometer" that you gateway to this E25 unit for it to show the information in the App. The unit itself does look like a USB drive. So, that part is correct. It also worked on the Aero Wave Fan, though I did have a problem with it pairing on an older phone (Samsung Galaxy S9+), and had to use on a newer one that I didn't want to use. Hence the 3 stars for all these issues.I will say that Customer Service got right back to me on the issue with the App, and that is why I'm providing the information on the other unit you must purchase. I have sent them a screen print of this ad in response.

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 UseRight 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 & PerformanceI’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 GrowersVIVOSUN’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 & ReliabilitySo 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 devicesFinal Thoughts – A Solid Controller with Room to GrowThe 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.
