It's written in C++. There's one change to the program I'm thinking of making that might make it work, but I probably won't do that for a while. I also want to roll in the functionality I currently have in an Arduino for supporting load measuring. Features diverse load control; also capable of charging over … The BT-1 Bluetooth module is a great addition to any Renogy charge controllers with a RS232 port and is used to pair charge controllers with the Renogy BT App. RX to GND will be a very low non-zero value if I remember correctly. Just read the next few posts. I'm looking for documentation for the serial protocol. On my Rover PG 40A that the current and power measurements work. Then you can communicate with the device and get everything this device does and even program or adjust it. After pairing is done you can monitor your system and change parameters directly from you cell phone or tablet. RS232 port allows the Rover PG to communicate with the BT-1 Bluetooth module, which can pair with the Renogy BT smartphone app 9. It seems like the wire that I am working with has a coil to it, and that coil is always trying to return back to its coil shape after it gets straighten out. Some clever dudes in this thread. This is very appreciated. The Renogy BT-1 is a great addition to any compatible Renogy solar charge controllers. So you can always be sure that the 2 middle pins are both ground, but make sure to check the outside ones. I opened a different thread about this problem. I discontinued the effort when I found the Wanderer 10A does not support current measurements. Renogy Bluetooth Module with RJ45 Communication Port, ... BT-1 RS232 3.9 out of 5 stars 704. It is compatible with select Renogy charge controllers through the RS232 port. The board itself is, I think the size of a quarter, you will probably need a very sturdy surface and some good screws. Well, I didn’t find any well documented article on google for connecting Arduino and raspberry pi over bluetooth HC-05. Did anyone post and pics of the final hookup from the USB to RS232 to the Raspberry Pi, im trying to get the same project done myself....any help would be highly appreciated. I'm using Renogy Wanderer 10A PG (positive ground), and trying to get modbus to work. It uses an INA219 over I2C rather than reading the mV directly as you have. Powered by its RJ12 communication port, the BT-1 provides wireless monitoring of system data through the Renogy BT/Renogy DC Home smart phone App. I'm using ESP32 and ModbusMaster library. The Rover came with a 6pin network plug to USB cable. RS485 allows Rovers to be parallled. There, you should always be able to find the quickstart. It is dedicated to running remote servo drives via Panasonic's RTEX Real The MC4N-RTEX extends the MC4N range of Motion Coordinators for networked drives which started. You've already done the work, I don't want to mess up such a simple step. I measured the voltage on what I had actually connected and I realized I had sent 15V through the pi's GPIO. Can someone tell me the pins from left to right if I were looking at the controller mounted on a wall? I don't know what it is, but it should probably be >4. Rover 60 Amp MPPT Solar Charge Controller Nominal Voltage: 12V/24V/36V/48V Auto Recognition I'm working on my lab bench with power suppy to the battery at 13.5 VDC, Load to an electronic load running up to 0.6 A, using node.readHoldingRegisters(0x0105, 1). What is the correct Modbus address of the charge controller?? The newer ones on Amazon don't come with that cable anymore :/. Are you referring to the sense leads from the shunt? I'm trying to connect the ESP32 directly to the micoprocessor of the Wanderer, since they will be located in the same box. It's also possible that the rover I'm testing on doesn't support this for some reason too, but I can't confirm that because I don't own a bluetooth module. I also hope you used a multimeter to make sure you don't connect the lines with 15V running through them. You should get a negative or positive voltage around 5.6. So, my project is, to have solar power in my greenhouse. I'm using a Pi to talk to my Rover using Modbus. Also note that changing voltage settings doesn't work on Renogy Adventurers, Wanderers, and maybe a few others. DOWNLOAD LINKS Thanks, got it. Aluminum heat sink allows for efficient heat dissipation. Rs232 port allows the rover pg to communicate with the BT-1 Bluetooth module, which can pair with the Renogy BT smartphone app. RS232 and RS485 ports. How to confirm your PC com port, usb-rs232 adapter and serial cable are working with a loop back test So far no luck. Automatically detects 12v/24v/36v/48v dc system voltages. You can still see my solarthing project here: https://github.com/wildmountainfarms/solarthing, Right now, most of the info on how to set it up is on the quickstart here: https://github.com/wildmountainfarms/solarthing/blob/master/other/docs/quickstart.md. Renogy BT-1 Bluetooth Module(optional). Would anyone here be willing to sell or make a cable? Awesome. Yes, this uses quite a bit of juice when you do a start up, so I was thinking of using a Raspberry Pi.Since I am not a Java tinkerer, I would like to use Python instead. This updated model boasts an increased signal range of up to 82 feet and an additional LED to indicate when your devices have synced. However, now that I look at it, the methods that aren't implemented in that library are completely useless, to me at least. One that uses JSON to communicate the information is nice too.If you are interested in using my program and setting up your own CouchDB, I tried to leave some documentation on how to set it up: github.com/wildmountainfarms/solarthing/blob/master/couchdb.md and github.com/wildmountainfarms/solarthing/blob/master/solar/README.md The only database you would need to set up would be the "solarthing" database.
