Review on 📶 Enhanced Communication for Renogy Charge Controllers: Introducing the Bluetooth Module RJ12, Compatible with Rover/Wanderer/Adventurer, BT-1 RS232 by Daniel Pierce

Read all BT-2 reviews. everyone has problems with it. I compare with renogy dcc50s. it worked with the first pairing with android. I was able to get the dcc50s history and change the charge profile to custom and see the solar input. Pros: It has great features when it works properly (every review has connection issues) Cons: The app doesn't remember the connection so you have to do a search every few hours. I couldn't connect anymore. It shows the device is connected but no data is being transferred. it's basically a brick. No setup documentation has attempted to unplug the device from the dcc50s and remove all connections on the dcc50s to reset everything. still nothing transmits any data. it's PITA to do everything as it's not very affordable. That was released too early imo going to Renogy won't help either. ticket problem. forgot to get an answer
