Tmall Genie controls ESP8266 to light up LED lights [Copy link]

 

There is no connection between Tmall Genie and esp8266, so how to use Tmall Genie to control esp8266?

This tutorial uses the Scallop IoT platform (http://www.bigiot.xyz) to connect ESP8266 for Microython to Tmall Genie.

step:

1. After applying for a Scallop IoT platform account, create a new device and obtain information such as the device name, device user, and device key.

2. Flash the micropython firmware into esp8266

3. Upload the mqtt library (see attachment)

4. Upload main.py

5. ESP8266 connects to WiFi

6. Run main.py

from simple import MQTTClient
from machine import Pin,Timer

#led选择G4引脚控制
p4 = Pin(4, Pin.OUT, value=0)

# MQTT服务器地址域名
SERVER = "bigiot.xyz"
#设备ID,user是扇贝物联平台注册的用户
CLIENT_ID = "{{user}}_esp8266"
#订阅开关主题,user是扇贝物联平台注册的用户
TOPIC = b"{{user}}/{{user}}_esp8266"
#设备用户
username=''
#设备密钥:
password=''

def sub_cb(topic, msg):
  print((topic, msg))
  if msg == b"on":
    p4.value(1)
    print("1")
  elif msg == b"off":
    p4.value(0)
    print("0")


def main(server=SERVER):
  #端口号为：1883
  c = MQTTClient(CLIENT_ID, server,1883,username,password)
  c.set_callback(sub_cb)
  c.connect()
  c.subscribe(TOPIC)
  print("Connected to %s, subscribed to %s topic" % (server, TOPIC))
  try:
    while 1:
      c.wait_msg()
  finally:
    c.disconnect()

Like, I just used Beike IoT to implement this function today.

Try Scallop IoT, the platform is completely open source.
