The UX needs some work on the app. The devices you add to the app should be shown when you open the app. Currently you open the app then have to scroll through the tabs to get to the Controller tab to see your controller. Better UX would be to show all your devices on the first tab so you don’t have to scroll through them. Remote access is great!

I bought the entire setup with the Icontoller and Ihub. Every single time one of them updates, I loose some sort of functionality in one or both items. First it was the ihub. I updated to the newest version and lost the ability to control light 2. It works perfect directly plugged into the wall outlet and it works if I plug it into the icontroller. The ihub no longer recognizes it. I contact customer service who can’t comprehend what I’m saying. They want pictures. I sent them still they can’t comprehend what I’m saying. I made a video but since they have no access to social media, they asked that I download some app to send them the video since it won’t play in the email. The app they require doesn’t work either. Now the icontroller has updated and it’s not even recognized in my app any longer and neither is the ihub. I can’t see anything. None of the Bluetooth is working. This company is terrible and highly frustrating. I will never buy another mars hydro product.

I had a very easy time connecting the app with my iControl. It was literally plug and play with the iControl and the other devices hooked up to it. The app is easy to navigate and straightforward. I am having not difficulty with the ability to control all of my Mars Hydro devices consistently and with ease. I am currently using an iFresh (in-line fan), a clip fan, thermometer/hygrometer, and the FC4000 light. Updates are still being released on a regular basis, so hopefully it will improve with time.

No issues with the app so far, seems pretty straightforward I read another review stating you needed the old app to connect the inline fan. It’s stupid but you have to connect the inline fan to the “Device” port of the smart controller, not the “Fan” port (as indicated in the instructions). They provide a splitter with the smart controller so you can have the fan and the sensor in the same port.
