I'm using this module to replace webservicex currency rates importer: https://github.com/philwinkle/Philwinkle_Fixerio

It is working ok when I hit import and save in the backend.

But I want to run it via a cron.

So I added to the module's config:

<crontab>
    <jobs>
        <fixerio>
            <schedule>
                <cron_expr>* * * * *</cron_expr>
            </schedule>
            <run>
                <model>fixerio/import::_convert</model>
            </run>
        </fixerio>
    </jobs>
</crontab>

And then run it with magerun:

./n98-magerun.phar sys:cron:run fixerio

It appears ok in the database and don't get errors in the console.

But the rates aren't modified in System -> Manage currencies.

If I insert a random value and save it then after the cron it will not update.

Any ideas? Thanks!
