Style: E42A+ Controller
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.

Style: E42A+ Controller
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!

Good controller, well featured. The user interface (on the panel) is a little tricky to dial-in, but once you get the hang of it, programming is pretty simple. The magnetic back is a nice feature for affixing the unit to a metal pole or using the metal backplate for mounting to fabric, etc.
