Heartbeat

[Tokatubs]

Have a lot of knx products that send out a heartbeat once an hour or so. But was trying to wrap my head around how to get this working 
Example
Heartbeat sends 1. So the value last value will always stay 1, but i guess i am looking for something that can change the group adress to 0 if no new 1 is received within an estimated time.
And then visualize it like in the pic. Thats my goal anyway. 

Any thoughts?

Reset the heartbeat once it gets 1, and then have logic say if object is not 1 within given time, set alarm.
