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.

Can someone please confirm, that after NR server restart it works automatically as expected? Not sure if there is something wrong at me or it is "normal" behaviour that I need to enter new tokens upon NR reboot. Thanks!

i confirm than it's works after reboot NR server with the store variables on local filesystem.

If you need to enter tokens upon NR reboot, that means that you don't store variable on filesystem, so they are lost when you restart. Have you applied the procedure explained here ? https://gist.github.com/matz33/843165d0046cac534864b65e633801a5?permalink_comment_id=4785938#gistcomment-4785938

Sorry, not see that, will try when I fill learn how to edit those files NR config files manully outside NR.

But one more question - if I set global variables with current tokens after NR reboot using injection of "Set info first" the tokens should work, no? The issue is that I need to generate new ones on dev.netatmo after reboot, than I inject them using "Set info first" to global variables and it works again... Mayby I am not right, just to understand that.

@Kositch: If the tokens are stored in the local NR filesystem you can reboot your system any time and have to do nothing more.
Only if your reboot is later than the token is valid (for eg. if you stop the system for some hours and make a reboot), you have to get some new tokens from the dev portal and start the process in NR again with the first step.
To put it in a nutshell: A normal reboot from the running NR system needs no further action...

Hi, i am really a beginner, got my station working before they changed it. It copied the flows, imported them and put all the data in. I created new tokens on the NetAtmo page. Unfortunately, I don't get it working. Could you please help me because I really need the NetAtmo data in my Node red system. This error appears at the end 12.6.2024, 20:59:14node: Netatmo Data

Thanks very much for your support.

@morpheus1984

can you try to configure it again (as described in the Readme, read carefully)… you maybe made a mistake at the configuration.

@jostrasser Mhh, i copied the complete flow and added my different tokens. So i think i cant do so much wrong. 🤷🏼 Do i need the additional Oauth2 nodes to get the tokens? Until now i just used the Flow i copied from here

No, this flow and a fresh token pair should be enough. And you are always getting a „Access token is missing“?

@jostrasser checked all again, got new tokens from Netatmo, always same error. Is there something special when working with variables? I don't do that for other things in node red right now.

Thanks for helping.

Update: it all works fine with the original code provided above. I used another oauth2 node called node-red-contrib-oauth2. that does not work. somehow it generates another refresh and access token pair (not sure how that is even possible) and that fails after a while.
I was in contact with a Netatmo supporter, he told me that they deactivated recently the usage of parallel token pair usage. Now only one pair will be valid, all others invalid. That is why this method worked before but now not anymore.
so all fine on my side :) happy with the code provide. thanks @matz33

Again problem with token:

Tested regenerating token, but it doesn't solve the problem.

Not here... works flawless.

Same here,... I also restarted the whole Node-Red installation (because I updated to Node-Red 4.0). All is working flawless.

Again regenerated tokens and it change also first two credetinals. Seems to be ok.

i have the same problem as @morpheus1984 "Access token is missing"... do i need to update Node-RED ?

yes - you should!
