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]
    client_id = ************************
    client_secret = ***************************
    refresh_token = ************************|********************************
    driver = user.netatmo
    mode = cloud
```

I removed the username and password variables but added the `refresh_token` manually
because the configuration was not properly written by `wee_config --reconfigure`.

A restart of WeeWX should fetch the data again.

```console
$ doas rcctl restart weewx
```
