Some routers isolate your wireless clients from each other and/or from your wired devices. Check your router settings.

And of course ping is the start of any network troubleshooting.

Thank you for reply; there isn't isolation between wired and wifi network

I think it's not a problem like you described.
Sure! ping is a very valid help for troubleshooting!

I can con connect from outside house to home raspberry using a ssh tunnel and from raspberry I'm able to ping the device in my network,

from raspberry if I ping the broadcast address of my private network I recive only replies from wifi device.
from my iphone if open the browser and I type the ip_port i reach the remote page on raspberry.
from the APP if I type the ip and port I can manage the raspberry.

Maybe the problem is the APP ?
how do the discovery works ?
Is the something I have to check on my router and access point device ?
Next step is to attach raspberry to wifi using a dongle..
