How to catch timer alarm signal on a siemens oven ?

[liouma]

Hello,
I have a SIEMENS oven running with home connect.
I'm trying to trigger some events when my oven's timer alarm rings.

I tried to trigger an action when entity "alarmclock" gets to 0 (the end of the countdown) but it is not reliable.

Before HA, I was using an other system called jeedom with a similar integration. There was a fiels 'alarm' and it was very reliable, that's why I'm not worried about the capabilities of the api to transmit the required info.
But I can't get it working under HA.

Could anyone help me please ???
Thanks a lot :)
