Works for Bouge RV solar controller
The internal BT failed in my BougeRV solar controller which has a data port. I plugged this BT-02 into it and I once again have the Bouge BT bluetooth functioning. No need to use Renogy app!Just plug this in and your orig app works.

Works good
Works good. Be careful to get the right one. Some older model charge controllers only take BT-1.

Good info - drawback is temp reading stays on Celsius instead of Fahrenheit
Most of my Amazon purchases for my van conversion solar system have been Renogy products. They are a trusted name in the solar industry and the BT-2 is the newest of the bluetooth modules. It is plugged into my Renogy charge controller to give me up-to-date information on the solar charging status. The only negative thing is the temperature readout on the app is in Celsius - not Fahrenheit and I have not been able to change it through any of the settings.

DC Home App on IOS don't work, don't know about android phone
Downloaded DC Home App version 1.8.29 to run on IOS with iPhone 6s, app failed to launch everytime. Please fix it ASAPUpdate on Dec 1st 2023DC Home App Version 1.8.30 for IOS was released on Nov30-2023, still failed to launch everytime.Previous App version from several months back works for BT-1, now the new versions don't work for BT-1 & BT-2. Is there anyway I can go back to old release? By the way, Renogy BT from over a year ago still works for both BT-1 & BT-2Update on Dec 24th 2023DC Home App Version 1.8.31 for IOS was released on Dec20th-2023, now works on iPhone6 like a charm. Thanks!!!Now requesting improvements:1. Can we have status update rate as a user option down to every 1 sec rather than once every 30 secs? Would be really nice to see constant update instead of waiting 30 sec when testing solar panel setup2. I know there is a swipe down & release for manual update, but that change the status info display position and is a pain to scroll screen when your hands are not free. Can we have a smaller animated solar/charger/battery section, reduce the blank space in the "battery info" & "solar info" sections so that you see main status of interest without screen scrolling? Right now I am still using Renogy BT App for setup testing, and that App is not stable.

Disappointing - I used to be a Renogy fan
My experience with the BT-2 spans over a year. After finding emails for US based staff for Renogy, I ended up interacting (via email) with an Engineering director in China.Environment and background:I'm in California. Prior to the series of activities associated with the BT-2, I had purchased various Renogy products including five LiFePO 100 amp-hour batteries, six solar controllers, ten or twelve solar panels (all at least 100 watt, hard-framed and flexible), 12v DC power 1000 watt inverters, and various cables, tails, fuses inline power meters and BT-1 modules... all to build a few solar generatorsPros:The panels, cables, LiFePO batteries have been behaving fine.All but one solar controller have been fine.Cons:This Ratings link is for the BT-1 and BT-2 modules. Unless the person writing the rating specifies which they are reviewing, it is impossible to know which is being reviewed.There is nothing in Renogy's documentation that says current firmware must be present/active in the Renogy LiFePO battery to which it is connected.Updating old LiFePo battery firmware is challenging, at best.There has been no way, until now, to know what firmware is active in the Renogy LiFePo battery.The BT-2 does not do a lot - it is the connection between the app (smartphone) and the Renogy LiFePo battery.The BT-2 module itself seems to be OK, but the (iOS) app was not so OK.* After accessing the BT-2 app, leaving the app did not tear down the Bluetooth connection. (this was resolved during my year of working through what was originally a BT-2 issue that ended up being a LiFePo battery firmware issue).* There is a "social media" part of the app that is unnecessary. But you can earn points for products. There is no way to know what safeguards are in place from a data security perspective.* Renogy customer service first contact was horrible. Winding through the maze via emails was time consuming, but somehow I ended up with the Engineering Director in China - This person was great.* When the iOS app is connecting to a battery, if "1 batteries" is selected, the app won't recognize that single 12v 100 AH battery. If "multiple batteries" is selected, the iOS app will connect to the single 12v LiFePo battery.(I specify iOS app because I don't know if the Android app behaves similarly.)Ultimately, I ended up sending all of the (in-service) batteries back to Renogy (US) for firmware updates. After a few months, all battery firmware updates finally got done. One of the reasons it took so long was these batteries were all in service supporting the solar generator in which they were installed. I had to replace the Renogy LiFePo batteries with 100 AH lead acid batteries to remain in service to get the updates done. Swap one or two batteries, send them to Renogy to get updated, wait, get the updated battery back, swap with lead acid battery, move on to the next solar generator.The iOS app + BT-2 + current LiFePo battery firmware are behaving relatively well. Getting here was time consuming and frustrating.If you purchased your Renogy LiFePO batteries 2+ years ago and are having problems getting the BT-2 to work, my guess is it is not the BT-2, but the battery firmware version. Good luck getting the battery firmware updated.To top it off, the chronology I had posted with the excruciating detail of the challenges getting through this ordeal was deleted. I did not received any notice from Amazon or Renogy as to when or why. I still like Renogy products, but won't be buying from them anytime soon... Without good customer service first contact, I no longer recommend buying from Renogy.

The module will show but doesn’t analyze
Simple Renogy BT-2 module configuration still a bit cumbersome in the app. It doesn’t recognize its Renogy BT-2 module by scanning the bar code, but will automatically detects the module but not intelligent when there is only ONE bluetooth item and doesn’t proceed automatically. The second issue when App is launched, its not automatically connect to BT device but has to asked and confirm the device again every time user launch it. Not a smart app as it requires too many interventions from user. Once these clunkiness satisfy, it can produce realtime output volt/watt/amp/temperature of auxiliary battery, and input starting battery volt/amps which exactly what user want to see. But again, no analysis like efficiency between input and output, trouble code, diagnostic, etc presented to the user

Just works
Works perfectly fine with renogy products. Connects instantly and flawlessly.
