+I got an email from another weewx-netatmo user Patrick yesterday, in which he asked if
+my WeeWX installation was still running, because we use the same extension to fetch the
+weather data from the netatmo servers (this method `cloud` is already rediculous, but it
+works with that hardware, so yes...).
+
+After looking on my servers logfiles I could confirm the extension wasn't working as
+expected any more.
+
+Today [I found an actual fork of the fork of the original extension][forked]:
+
+<https://github.com/Buco7854/weewx-netatmo>

+
+## And this is how I upgraded the netatmo weewx extension
+
+Uninstall the old extension:
+
+```console
+$ doas -u weewx /home/weewx/bin/wee_extension --uninstall netatmo
+```
+
+Download and install the new extension:
+
+```console
+$ doas -u weewx wget -O weewx-netatmo.zip https://github.com/Buco7854/weewx-netatmo/archive/master.zip
+$ doas -u weewx /home/weewx/bin/wee_extension --install weewx-netatmo.zip
+```
+
+Go to <https://dev.netatmo.com/apps/> and update your app to include a `refresh_token`.
+
+Update the configuration with
+
+```console
+$ doas -u weewx /home/weewx/bin/wee_config --reconfigure
+```
+
+That should already ask for your refresh_token. Double check this in your `weewx.conf`
+configuration file, as it might not get written properly (like in my case).
+
+The configuration should look like this now:
+
+```toml
+[netatmo]
+    username = email@address.com
+    password = ****
+    client_id = ************************
+    client_secret = ***************************
+    refresh_token = ************************|********************************
+    driver = user.netatmo
+    mode = cloud
+```
+
+I basically left it the same as before, but I had to manually add the `refresh_token`
+line to the configuration.
+
+A restart of WeeWX should fetch the data again.
+
+```console
+$ doas rcctl restart weewx
+```
