Size: GrowHub E25
Style: Expansion Port
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.

Finally got this controller E42A+ GrowHub and I was able to manually navigate through the settings and proper wiring position/connection set-up, RJ45 and RJ11 with the AeroLight SE. The manual does not tell you that in order to run 2 AeroLights, you will also need a two-way splitter for RJ45 & RJ11. I am including photos with this review that show the correct wiring ports for all connectors. Also, after you get your lights connected, in order to turn on the lights you must toggle up or down using the arrows and then push on the check mark symbol to turn on after setting a light percentage, IE; 35%, 65%, etc. There is also a photo showing the split connection to the second AeroLight SE. This will help a lot because the instructions for the new E42A+ are very basic and really only covers hooking up one light. Nice unit but new and this time without the App and it works great. No E25 dongle needed, devices now connect thru C cables included with each device such as Duct Fan and 6 to 9 inch wind fans. Good Luck all!

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!
