update: ok, this is wired, but it worked! bonjour from apple site (standalone installation) didnt helped. but bonjour from itunes (extracted like @György-Farkas did) worked. Have no idea why, might be the version. Thanks to all!

@benthenchelys Good question! Unfortunately, there are no local URL endpoints for the services exposed on the Cloud. That's where our Cloud <-> Device connection comes into play. However, all of those services are available on the command-line through the ubus. Check out our ubus tutorials for more info. Your other devices and sensors can potentially use SSH to trigger ubus commands. Hope that helps!
