Renogy BT

I use this to switch my MPPT controller on and off by changing the max charge voltage setting. I have set my own User profile for charging my LiFePo battery. It works with my BT1 dongle. That’s in the motorhome wardrobe and I can connect from about 4 meters away. As it’s on my driveway, I don’t have to go outside! I find it really very useful. So much better that trying to do stuff on the controller itself. It shows me the panel’s present output and the present level and mode of charging. Volts, Amps and Watts. It’s not perfect as it always shows capacity as 100% but it’s so useful otherwise and, anyway, I can deduce that quantity from the voltage displayed. I’d be lost without it. Maybe they have improved it and/or the BT1 dongle since the bad reviews, here? (I couldn’t get the DC app to do anything useful!)

Charge you an absolute bloody fortune to get the whole system and with Bluetooth feature onto the device and then do a crappy app that keeps showing system error every time you login, never remembers much information about the battery amount. Ridiculous

No change of opinion since my last review. Connection problems even over just 5mt. Figures shown in lists are switched in graph mode, e.g. Power generated shows as power use same day in graph mode. In graph mode, year 2022 is selected yet graph is showing 2016 and this cannot be changed. Constantly disconnects and reconnects while in use. Considering the cost of the equipment, you would think they could provide an app that works. I’ve gone back to eco-worthy where I’ve had a far better service.

Renogy have good products but PLEASE change app . Your app is totally useless . Not working at all .

I’ve paid for the Bluetooth unit and the app makes it unusable. Connects a few times then fails to connect at all. Says it’s connecting but it never actually does. The only way to reconnect is to disconnect and reconnect the Bluetooth module. Bluetooth was better than this ten years ago. There’s no excuse for providing something this hopeless in 2021. Renogy…..talk to me…..the app doesn’t work.

The review title is about as much use as the module. Very poor Bluetooth connection reliability. A ton of data when it works, but if you search appgrooves or similar there are soooo many bad reviews. A shame as I've paid a lot of money for all my renogy kit.

The look of this apps various screens is very nice. They have a wealth of interesting data such as Solar power input Volts, Amps, Watts Battery charge %, input charging volts, Amps and watts. Output to load, volts, Amps and watts. There is a history tab that shows you the above info by day, month and year. The area that this app would be able to improve on is. 1. The history data should transfer to the app rather than pulling the data on demand via blue tooth every time you want to look at it. 2. The data needs a real-time cloud type storage. I would happily pay a subscription for that because the Bluetooth does not transmit much more than 15 meters and mine is 20 m away down the garden. Other than that, this is a good app that needs some embellishments like the afore mentioned to make it great.

This app connects and then crashes 9 out of 10 times when I open it. Not sure what might make it less prone to crashing but it could really use some attention from the developers.

I can’t believe Renogy who makes excellent products has released (and updated) such a terrible app. The charts are clunky and can’t scroll to different dates, 2016 is still displayed at the bottom corner, the battery voltage only takes one point per day so you can’t see a nice curve, only a 5 day spikey mess. It does handle the real-time charge current and battery voltage readings well, so that’s a plus. Please do better.

Echoing what others have said - there aee just so many bugs in the app that it’s nearly useless. It feels like a hobby given how poor the interfaces and how many books they are. It hardly seems like an app from a professional company that delivers pretty high-quality batteries. Obviously they don’t care about it as it hasn’t been worked on in over a year.
