Product is working flawlessly and provides much vital information on the power usage of my current arrays

Works great

Steve Drennan on Aug 11th 2021

I am using this with an Apple iPhone 10 and it works perfectly. Installed the app, plugged the module this into the battery, and it was detected moments later. Couldn’t be much easier. The only thing they forget to tell you is that if you want to refresh the status, you need to pull down on the screen. I thought the unit wasn’t working properly for a few minutes until that point but it works well and from quite a distance away too.

Hardware good, software very poor

Jake Graham on Jul 26th 2021

This unit works decently to give you an overview of your system. The hardware seems to be fine, but the software is very poor. The Renogy BT app would not recognize my 100ah smart battery, but the DC Home app would. Which wasn't on the Google Playstore a few weeks ago. I had to find it from a third party website. It was a frustrating time to get things working, and even now, I can't use the Renogy BT app to access my battery information. At least the DC Home app works for now. Hoping they improve their software soon.

Great Module

Steve Mohammed on Apr 30th 2021

IT works great. The only problem I have is when the APP gives you an error code, there is now way to find out what that code is unless you call the support line. There should be a list somewhere so you can easily trouble shoot your issues.
