Renogy Bluetooth Module RJ12 Communication Port Compatible Rover/Wanderer/Adventurer Charge Controllers, BT-1 RS232,Black

Quick summary: this Bluetooth adapter is simple to install, configure, and use. The information it provides to a phone is very useful and much more convenient than going and looking at the charge controller.More detailed review: I have a Renogy Wanderer 10A charge controller, 50 watt panel, and a LiFePo4 battery to provide 12V power for lighting and a small fan in my shed. I wanted to be able to check on the system and verify it was working correctly without needing to go out in the shed and directly look at the controller, so I purchased this Bluetooth adapter.Connection is simple: it uses a modular connector identical to those used in landline telephones, so it’s literally plug and play.Pairing with Bluetooth on a 2020 iPhone SE is quick and easy, as is using the app. It provides all the real-time status in a convenient and useful layout.The range is enough to go about 30 feet through the shed and house walls. I did test it up to 100 feet away with no obstructions, but it was not able to communicate with my phone at that range. I suspect the range estimates are idealized and somewhat overstated.Useful feature: if the controller’s output is set to manually switch the load on and off when the Enter button is pressed, you can remotely switch the load terminals using the app.The only downsides seem to be related to my charge controller, not the Bluetooth adapter. The controller is extremely basic and doesn’t do any internal data logging or storage at all beyond saving the settings. Thus, the only information it outputs is just the real time status, which the Bluetooth adapter faithfully transmits. The app is capable of many features that this particular controller is not, such as renaming the controller and logging historical data about power generation, consumption, battery state and voltage, etc. I presume more advanced Renogy controllers would be capable of logging and sending that data, though I wish the app would hide the fields and options that the controller doesn’t support.Bottom line: if you have a Renogy controller and want to monitor it without needing to directly look at its display, this Bluetooth adapter is the way to go. In my case, the controller cost less than the Bluetooth adapter, but getting the adapter was definitely the right choice.

Works great lets me know all the info I need to know from how many watts my solar panels are bringing in to the percentage of the battery. the bluetooth range is decent it works up to10-12feet. The device itself is pretty small, won’t take up much if any room, It also comes with a thermometer to check the batterys temperature which was nice. The quality seems good so far. You do have to download an app to use this product but that wasn’t an issue, It was very easy to hook up to my battery and use. overall I’m pretty happy with the product

Like always with Renogy Products, they are dependable and great quality. We have many Renogy solar products and always use Renogy! Very Dependable!

First of all the Renogy DC Home app locked up my android phone which I had to restart, then when I reinstalled it I couldn't get passed the user name it wanted giving a cryptic message something like user name already taken, it finally took another name. Turned on Bluetooth, it found the Renogy device but will not connect, everything was tried but it appears "dead" even though it's green "on" light is lit. Unfortunately the Renogy Wanderer Li 30A 12V PWM Negative Ground Solar Charge Controller doesn't have an LCD display so without the Bluetooth adapter you have no idea of battery voltage or charge rate. The Renogy DC Home App really needs work before it works as well as Govee Home Bluetooth devices which work really well.*UPDATE - After several tries the software finally installed and Bluetooth was able to connect and I was able to monitor the charging status of the Renogy just fine, therefore I've upgraded my review to four stars.

This Renogy BT-1 Bluetooth Module is a must-have accessory for anyone with a compatible Renogy charge controller. It's an absolute game-changer for monitoring your solar power system.The setup is incredibly simple-it just plugs into the RJ12 port on the controller. Onceconnected, it syncs seamlessly with the Renogy DC Home app on your phone. This gives you instant access to all your system's data without having to be right next to the controller. You can check battery voltage, charging status, and daily energy production from anywhere.It's a huge convenience and makes managing your solar setup much easier. If you want to keep an eye on your power system without the hassle of a physical display, this module is an excellent investment.

Range is pretty amazing, works better than expected.

The Bluetooth connection range is about 150+ feet so you can monitor the systems performance conveniently. Tells you all you need on your phone.
