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

Very useful the fact that I can control it from my phone! 👍

Gain controller over you inline fan or lights with this unit. I use mine for the inline fan to regulate the inside the tent temperature. The app has a setting where you can set low & high points to temp and humidity giving you full control. It has an auto setting with working with the VIVOSUN temp/humidity monitor. The value for the money is excellent and every grower needs automation like this.

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.

Does what it’s supposed to do. VIVOSUN makes a great product. I havnt had a bad experience with them yet

This controller is easy to install and setup to use your Vivosun Lights.

They don't explain it's got limited features for duct fan venting. It has no auto control meaning you can't set it to turn in the exhaust fan if it exceeds a high temp limit. All their other controllers do. Its pretty much useless to control the duct fan.I contacted vivosin but very slow replies, very slow!! Poor product and poor customer service.Don't buy!!!

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.

If you don't want an actual grow hub but just want to control your inline fan from your phone,run recipes and cycles then this is the perfect little Bluetooth controller! You can set it to turn on and off when your tent gets to a certain temperature 🌡 or humidity, awesome tool ive never had to much control,get a security camera and face it towards a hygrometer and you can control your environment down to the ⁰ or %rh
