Receiving SSDP:alive & byebye in Device-Type Handler

Developer Programs Writing Device Types

Hello~

Currently, I am developing new thing which is LAN-Connected device.

I want to know the power(or hub-connected) status in Device-Type Handler.
So now I have an idea using SSDP:alive & SSDP:byebye.
But I can’t find how to receive this broadcasting message.

As I know, Service Manager can receive the response of M-SEARCH.
I think Service Manager or Device-Type Handler can also receive SSDP:alive & SSDP:byebye.

If you know, please help me.

I also interested in this. I want to build a switch device based on those events.
