Home Assistant on Synology NAS : How to use a Wemo switch?

So according to that topic there is Netdisco / netifaces issue on Synology NAS (non docker installation due to older non compatible NAS) :

I had to disable discovery & wemo in the configuration.yaml file to get rid of the error messages but is there a way to turn on or off a wemo switch with a script ? (my switches have static ips)

To my knowledge you do need netifaces to work with wemo and Chromecast devices.
Good thing is the procedure described in my previous post does work… I recently had to reinstall all my synology from scratch, so had to do this hole thing again… intalling the Christmas,etc… And still worked!
