+## Update on 16<sup>th</sup> July 2023
+
+{{< alert >}}
+Okay, just for your information. I no longer use Redhat on my servers and
+the following mentioned weewx-extension does no longer work, because Netatmo
+has [changed their authentication policy][1] for development apps and do
+not allow simple password authentications any more.
+
+[1]: https://dev.netatmo.com/apidocumentation/oauth#authorization-code
+{{< /alert >}}
+
+That means we have to update the extension to a fork that is recently updated.
+
+There are two Follow-up posts to this article that show the migration to an
+OpenBSD server as well as the replacement of the netatmo weewx-extension.

+- [Moving WeeWX to OpenBSD]({{< ref "2023-05-27-moving-weewx-to-openbsd/index.md" >}})
+- [Update WeeWX extension]({{< ref "2023-07-15-update-weewx-netatmo-extension/index.md" >}})
+
+I recommend reading the last one to get a working setup. If you want to have a
+nice status message on APRS I also recommend reading the first one too, because
+it includes a little script to accomplish that with python.

 ## Preparation
