GrowHub 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

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.

I've had the GrowHub for about 3 months now and I can't imagine living without it now! I have mine controlling an AeroLight AW200 grow light, 4x LumaRay Side Lighting Bars, AeroZesh T4 inline fan, GrowCam C4 and AeroStream H19 humidifier and it has been performing seamlessly! Setup was extremely simple, just running a cable from each device to the hub - or some connect through your local wi-fi. Adding new devices has been a breeze with no issues thus far. To be fair, once the initial setup was done and I got the GrowHub connected to the mobile app on my Android phone I rarely touch the control panel itself as I'm always in the app! The mobile app is amazing! I am in the beta program and the developers have been steadily releasing updates with great new features! There are too many features to list but some of my favorites are being able to check in on my grow cam along with the current climate conditions even if I'm out. You can use youe grow cam to record a time lapse of your grow. You can set a lighting schedule, intensity, and spectrum. You can set the inline fan to work on a schedule or to activate when pre set humidty or temperature conditions are met. There is a journal section where you can log your watering, nutrition, lamp height, etc. You can also attach pictures and video to each entry. You can view historical logs of your tents environmental conditions (temp, humidty, VPD). There are just too many great features with more on the way, I'm sure! I really can't recommend this product enough. It's performance has been perfect and keeps getting better. This WILL help automate and improve your growing experience!

Excellent piece of kit. So much on board capability for someone without a smart phone. Great build, and the mounting system works great, no worries of it ever falling.

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.

If you are deciding on whether or not to buy this and looking through reviews, ABSOLUTELY BUY THIS! I have been newly experimenting with their products and this controller makes so much possible with automating processes. I have relied on their recommendations with lighting, airflow, watering, etc. and have had INCREDIBLE results. The screen is lit nice and all of the information is right there. The WiFi connection was good and I can control everything from my phone with their really nice app. I reached out to their customer service with a few questions and received wonderful experiences there also. Quick response and helpful information. Can’t say enough good things. Really hope to get into one of their alpha/beta opportunities one day.

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 absolutely love this thing! It’s made my entire growing experience so much easier and better! No more guessing the average temp with the highs and lows of the day. It reads temp and humidity accurately and gives you control of your environment in a small touch screen. It also looks stylish outside the tent. The app integration is easy and super convenient. And since it connects to WiFi I love being able to check on the grow from anywhere! Definitely worth getting one for your setup

Won’t connect to my hotspot

Muy bien

Erstmal zum Verkäufer. Sehr schnelle Lieferung, TOP Produkt und kam gut verpackt bei mir an. Da ja das USB C Splitter Kabel so gut wie nicht erhältlich ist, ist das eine sehr gute Wahl zusätzlich zum GrowHub E42A um einen zweiten Vivosun AeroWave E6 Ventilator über die App zu steuern. Super einfach und selbsterklärend zu verbinden. Funktioniert ohne Probleme. Kann ich nur empfehlen ❤️ ich liebe Produkte von Vivosun ❤️

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

Fonction très bien pour l'instant pas de problème

Gestern bestellt, heute geliefert! THANKS! Kaufentscheidend: Bedienung des Zirkulation-Ventilators VIVOSUN AeroWave E6 Gen2 per Controller (somit auch via App), und die dadurch zusätzliche digitale Hydro+Thermo-Erfassung (anstelle separat-autarke Messgeräte) auf einem Blick. Bei uns dient dieser Controller für Hydro/Thermo-Messung + Luftzirkulation. Bei Licht und AKF-Lüftung haben wir für andere Anbieter entschieden, die über diesen Controller nicht bedient werden können. Die Gerätschaften können über die App noch feintuniger gesteuert werden. Controller funktioniert aber auch ohne App und VIVOSUN-Userkonto! App wiederum benötigt Kontoerstellung. Gerne wieder! Danke nochmals!
