Yeah, i finally have found it. 
Unfortunately you still can’t access the contdown value in the alert.
I assume that the reason is that it is a string. I think in order to access the counter in the alerts, it must have values in the right scale.
At least that’s how it is with the other indicators if you want to access the numeric value. If that were possible, your HybridCounter would be the only indicator of this type that can do that at all.
Thx Trib
