Hello,
The module communicates with the bestbeca.cn (ip: 59.110.30.249) where your thermostat is registered i.e. it does not communicate with the thermostat directly.
You need to register the thermostat first using the official app.
Once the module is in custom_components/climate/ just update your configuration.yaml to include:
climate:
- platform: wifithermostat
name: name_goes_here
api_key: xxxxx [<— this is the product id you will find on the label on the thermostat]
Finally, please make sure you use the latest code from github!
