I just published my two first Alfred workflows on Packal.
Wemo v0.2 allows to get the status of your Wemo switches and changing their status with a simple click.
It is based on a bash script found here in the comments.
Netatmo v0.2 retrieves weather information from your indoor and outdoor modules.
It is based on a PHP script found a long time ago on http://maison-et-domotique.com.
