MARS HYDRO 2025 iConnectu Controller, for New Version FC & FC-E & SP3000 LED Grow Lights, Bluetooth USB Supports Smart Grow System Devices, WiFi App controllable, Expansion Port for RJ12

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

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

Comes nicely packed, I've had for about a week works as advertised. For less than twenty dollars would be nice if manufacturer would just incorporate in the electronics of the light

Do not buy this bought it for indoor grow to use for adjusting light intensity. Does not connect to my iPhone Bluetooth the usb is not found in the MARS hydro app to connect it’s just not found so that you can use . I read other reviews saying the same about connecting issues but was naive it would work for me but it doesn’t . Don’t waste money . 2025 & companies are having trouble with Bluetooth connections is a bit insane EDIT; Guys at Mars Hydro reached out & got everything working Bluetooth is now connected & working . Great Customer Service with the step by step. Able to adjust light intensity from my phone now

Great for setting up a timer and easy to set up

Constantly fails to repeat the programmed light cycle. Difficult to setup. Not worth the value.

Doesn't keep connection, cost me a grow. I spent almost as much time trying to connect as being connected. Worked good but a little spotty @ times for about 4 weeks, wasn't too bad. Only cost $7, so I figured I'd take a chance even though the reviews said it was crap. In this case the reviews are right. You can roll the dice for the price but I wish I hadn't.

It is so easy to apply. It was a simple five minute setup. Just insert into USB and download application. It even is daisy chainable to the older versions of FCE and I assume FC models. I bought one and after I daisy chained two other lights to the app. controlled lights, they all are now app controlled. So cool. No need for other timers. I highly recommend this product because of the ease of application. No it is not needed but so worth the investment to ensure simple synchronization of multiple lights, and it's cheaper than most timers!
