Greetings,

I’m building an app for controlling my Volumio audio player. I set up discovery, and the device is not found yet.

My steps:  
file .homey…/discovery/ =\> volumio.json  
{  
“type”: “mdns-sd”,  
“mdns-sd”: {  
“protocol”: “tcp”,  
“name”: “Volumio”  
}  
}  
in the device there’s the “discovery”: “volumio” property.

Names I’ve tried: volumio, Volumio, \_Volumio, \_volumio

When I execute avahi-browse -a (from Linux) I see:  
…

- wlp2s0 IPv4 dionysos \_Volumio.\_tcp local  
…

The device has no http-secure protocol.

Could that be the problem?

Many thanks in advance!

Update: Het is gelukt!

Wat ontbrak was: “id”: “{{name}}”

En ik kwam erachter door in de commandline “homey app discovery create” te gebruiken.
