Get Netatmo Weather station data

README.md

Unfortunately the Netatmo node https://github.com/guidone/node-red-contrib-netatmo-dashboard is not working : Nodered crashes 5/6 times a day if you use it. The owner is not willing to maintain his code.

Here is a method to get the Netatmo Data without having to install a module, just using http requests. Here is how it works :

1. Enter your token and refresh token + client id and client secret in the node Set Netatmo Creds & Tokens. You can use https://flows.nodered.org/node/node-red-contrib-oauth2, or info here https://github.com/guidone/node-red-contrib-netatmo-dashboard#authentication to get it or any other methods

2. Trigger the inject node Set first info

3. Then, the inject node Start can be triggered either automatically after a deploy like I configured it (prefered method), or manually if needed

4. It will get the token, refresh token, and will refresh them after the expiration (returned in the payload by Netatmo) - 5 minutes

5. If error in getting the token it will retry after 1 hour. You can add any kind of alert (email, etc) after node Delay 1 hour on error to alert you that there is an error and token was not returned (time out etc)

6. The node Next refresh in... displays the next time the refresh will occur. This one and the associated "delay 1s" can be deleted safely if not needed

7. The token is stored in the global variable NetatmoAccessToken and is used in the http request after the inject node Get Netatmo Data.

Today, Netatmo informed about upcoming authentication changes, starting May 29, 2024:

Authentication update (second notice)

This is a reminder regarding our authentication update following the release initially planned for last fall which we decided to postpone in order to give our users more time.

Dear Netatmo developer,
Today, when you refresh an Access Token using the associated endpoint https://api.netatmo.com/oauth2/token, the Netatmo servers respond with a pair of tokens: an Access Token and a Refresh Token.

If the previous Access Token is still valid, the newly returned access token is identical but has an expiration time extended by 3 hours.

The Refresh Token is not renewed.

Starting May 29, 2024, this behavior will change to comply with the OAuth2 Authorization Framework RFC recommendations (section 10.4) and improve the security of our users' data.

When refreshing the tokens, the Access Token and Refresh Token will be different from the previous ones and the old tokens will be invalidated.

What does this mean for you?

If you already store the tokens returned by the API when refreshing your tokens, this change will not affect you.

If you do not update the tokens when refreshing them, your users will be logged out because the old tokens will be invalidated.

If for a given user, you have stored the same token in different places (for example: an application and its widget), you must have a way to synchronize them because the new token will be applied for the entire application.

Sincerely,

Legrand - Netatmo - Bticino

Does this impact our current workflow? Thanks!

Hi, thanks for alerting on this.
The workflow complies to the Oauth2 requirments : in the node "Store tokens & delay", it stores the tokens returned by Netatmo when refreshing them :

Thanks for confirming @matz33 ! Only to be safe ;) BR/JO!

Thx a lot for this great flow @matz33 !

You're welcome :)
