MARS HYDRO2025 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

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!

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 insaneEDIT; 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

FLAT OUT.....will not connect via bluetooth. I love the light, but a usb dongle these days ? How with a tiny bit of additional planning should have made this device actually function like it,s intended. A wifi chip built in the dimmer box would have worked well. And also with limited choice in controller for this doesnt help me either.

Why did you pick this product vs others?:ReputationFunctionality: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.

Love it work by my phone

Love using this with my Mars Hydro FC-1500 Evo light! Super simple app to set my timers and just able to quickly adjust on the fly! Keep up the amazing work Mars Hydro!!!!

Their app kinda sucks! It is not simple like the ac infinity app.

It worked well, but it wasn't what we were looking for
