/*
This example code is used to connect the Yeelink cloud service (Official homepage: www.yeelink.net).

The device required is just:

1. LM35 low cost temperature sensor or any device you used to upload data
2. And Wido

Note: Please don't forget to change the setting below before using!
1. WLAN_SSID & WlAN_PASS
2. API_key
3. device ID & sensor ID
