python控制網絡繼電器

網絡繼電器配置如下：

1. 搜索局域網網絡設備

 

 2. 參數配置&寫入配置

 這裏網絡繼電器作爲服務端。客戶端通過socket建立鏈接併發送開關指令(socket對接即可。mqtt根據需求配置(高版本mqtt協議不支持）))

 

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"控制繼電器通道{channel_id}開端口發送吸合發送：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關閉")
        return True
