python控制网络继电器

网络继电器配置如下：

1. 搜索局域网网络设备

 

 2. 参数配置&写入配置

 这里网络继电器作为服务端。客户端通过socket建立链接并发送开关指令(socket对接即可。mqtt根据需求配置(高版本mqtt协议不支持）))

 

import socket


def open_door(rely_host="", rely_port=12345, channel_id=0, timeout=5):
    try:
        client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        client.settimeout(0.5)
        client.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        client.connect((rely_host, rely_port))
        print(f"控制继电器通道{channel_id}开端口发送吸合发送：AT+STACH{channel_id}=1,{timeout}\\r\\n")
        cmd = f"AT+STACH{channel_id}=1,{timeout}\r\n"
        client.send(cmd.encode())
        print(client.recv(BUFF_SIZE).decode())
    except Exception as e:
        print(e)
        return False
    else:
        client.close()
        print("Socket关闭")
        return True
