How can I associate my Smarther or C300X13E account to my WWL account?

First, if you don’t have a Legrand account you need to create one on Works with Legrand and to subscribe to the Starter Kit
You must also have downloaded the Thermostat or Door Entry application and to have created an other account (you can use the same Email/Password as previously)
On the left side menu, click on “Account” and then on “Third-party access”
Sign-in by using your Legrand credentials
A message will appear to confirm the connection. You can now use the APIs
To use the “Try it”, you need to enter your Legrand credentials
