Doesn’t work
Bluetooth won’t connect Edit: seller reached out. The device does work but go to add the device in the app you have to turn dimmer knob all the way down to off and back up to about 80 percent back and forth over and over until the device pops up. Awesome customer service

Does not work- very very disappointed
I have tried everything, all the tricks. The Bluetooth for the fan and light does not work. Customer service tried to help but to no avail. My phone is still searching and the Bluetooth sounds really good but sadly

Works and Fits Perfectly
The MARS HYDRO 2025 iConnectu Controller works exactly as expected and fits perfectly with my setup. Installation was simple and everything connected without any issues. It does exactly what it’s supposed to do and makes controlling the system much easier. Very satisfied with this purchase and would definitely recommend it.

Does not connect - REVISED
App does not find the controller via Bluetooth. Turning dial on light 3 times did nothing. Tried old and new app and re-installed new app. Nothing. No “email the seller” option for help. REVISED REVIEW AFTER DEVICE FOUND VIA BLUETOOTH March 2026 Okay, it took some fast twisting but I was able to connect via bluetooth! Support contacted me after I left my first review and I was encouraged to try again and again. It was good to know I had the steps right. My problem was that I wasn't twisting the knob fast enough apparently. I had my husband give it a go as a last ditch try. Now that we have the connection, being able to set 5 timers at different intensities for the daily light is sweet. Light automatically comes on then goes through the timers and shuts off each day.

Better now, be paitent
Previously, I gave it a low star rating because I could not connect it, after trying all the tricks. But I kept it plugged in. After a week, I tried to connect it again, and it has been working flawlessly.

Could Be Better
Why did you pick this product vs others?: Reputation Functionality: Careful! This thing is quirky and doesn’t always connect and will log you out and you will lose the timer setting. Caused the light to stay on past the timer settings after couple weeks or so. Don’t touch the dimmer dial on the light or unplug this. You will lose your settings. App is confusing as well%:Went 7 hours past shut off and didn’t catch it at 6 weeks in flower. Switched back to mechanical timer. Hope I’ll be ok…not the best instructions or manual either. Great light though.

I figured I needed it, but bought an iHub-Pro & iControl. I know if those break down, I have these for backup.

Should be able to just plug it in and have it work. Don't even know if it turns on. Probably just return it
