Renogy Bluetooth SDK for Python

RenogyBT for Python SDK

RenogyBT is a Python SDK designed for Modbus communication with Renogy products. This project provides functionality to communicate with Renogy devices via Bluetooth.

Installation

Ensure your Python version is 3.6 or above. You can install the required dependencies using the following command:

pip install renogy-modbus-lib-python

Usage

Initialization

First, initialize the EnhancedModbusClient class to scan and connect to devices:

from modbus_bt_pkg.src.renogy_lib_python import EnhancedModbusClient

async def main():
    client = EnhancedModbusClient(slave_address=0xFF)
    devices = await client.scan_devices()
    # Select and connect to a device
    success = await client.connect(selected_device['address'])

Data Retrieval

Once connected, you can use the following methods to retrieve battery raw data and status information:

response = await client.get_hole_original_data()

status = await client.get_status()

Example

import asyncio
import sys
import os

from renogy_lib_python.modbus_comm import EnhancedModbusClient
async def main():
    client = EnhancedModbusClient(slave_address=0xFF) 
    connected = False
    choices = ["battery","controller"]
    try:
        # start scanning for devices
        devices = await client.scan_devices()  
        if len(devices):
            print("\nList of available devices:")
        for i, dev in enumerate(devices, 1):
            print(f"{i}. {dev['name']} ({dev['address']})")
            
        if devices:
            # select a device to connect 
            choice = int(input("\nPlease select the device type to connect (1 battery- 2 controller):"))
            if 1 <= choice <= len(choices):
                selected_type = choices[choice - 1]
            else:
                print("Input out of range, please try again")
                return
            while True:         
                try:
                    choice = int(input("\nPlease enter the device number to connect (1-{}): ".format(len(devices))))
                    if 1 <= choice <= len(devices):
                        selected_device = devices[choice - 1]
                        break
                    else:
                        print("Input out of range, please try again")
                except ValueError:
                    print("Invalid input, please enter a number")
            
            success = await client.connect(selected_device['address'])
            connected = success
            print(f"\nconnect status: {'success' if success else 'failture'}")
            
            if success:
                while True:
                    # send read command: get data
                    print("get data")
                    response = await client.get_hole_original_data(DeviceType=selected_type)
                    print(response)

                    # send write command: set data
                    print("get status")
                    response = await client.get_status(DeviceType=selected_type)
                    print(response)
                    choice = int(input("continue or exit? 1.continue 2.exit\n"))
                    if choice==1:
                        continue
                    else:
                        break
    except Exception as e:
        print(f"catch exception:{str(e)}")
    finally:
            if connected:
                await client.disconnect()
    
if __name__ == "__main__":
    asyncio.run(main())

Features

• Device Scanning : Use the scan_devices method to scan nearby Bluetooth devices.
• Device Connection : Use the connect method to connect to the selected device.
• Data Retrieval : Use the get_hole_original_data and get_status methods to obtain raw data and status information from the device.
