Ok, that's very positive thanks!

See:

iRidium should be in that list, Sonos now helps company's with communication.

Maybe that's the way we can make a reliable Sonos integration.

You mean test the app from win PC connected wired in the network?

Will test this, maybe STP is a problem?

Please tell me how to do this and with what software... I think problem is network because with same iPad and driver work fine... so only thing we then need to know is what's blocking the communication.

Switch is:

Unifi

Hi Aleksandr. Yes it works fine with BAOS and modbus.

Weirdest is that it works fine in other networks. / with other sonos players.

Sonos players are all up to date. i have connect amp, playbar, sub and play3 devices.

License type is Enterprise_plus so that should be good i guess.

Hi, got one project where no sonos player is found. I added the player IP adresses in the script and still nothing found. 

Router is Fritzbox.

Weird thing is that i can work with sonos from same devices using the sonos app. It works on iMac, iPad pro 12,9" iPad 4, iPad 3 and iPhone 6. on all these devices iRidium doesn't connect.

in i2 sonos did connect to the players.

Any clue what's wrong?

When i use the visualisation in other networks (exact same configuration) the sonos app in iRidium works fine.

Can there be an internal networking problem? Customer claims nothing is blocked and there is no firewall or something alike.

Found another small thing:

The checked box is quite big ;)

Presume you use portforwarding and connect through external IP?

Yes please fix!
