I just hope I can save my plants

Plants in veg and plants in flower and lights are doing whatever they want instead of connecting to the app I’m kinda freaking out they worked fine with the old app but I can’t get them to connect with the new one and now I can’t reconnect to the old app and my harvest is at risk and my plants are stressed

Absolute junk and customer service is worthless

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.

Good, most recent update really cleaned things up

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.

Network unconnected

Updated the app to the latest version and got hit with that… now I can’t use anything!!!

Good but UI needs improvement

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.
The user interface (UI), however, is very noticeably lacking polish. The formatting is a bit odd in some places.
The good thing is that none of the UI issues interfere with my 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.
