Sharing here as well…

Seems that (at least in my case) there might be a bug on Chrono When-cards (tested only stopwatch and timer), when triggered by minutes… here the full “story”  
[Double triggering (to start) of flow - Questions & Help - Homey Community Forum](https://community.homey.app/t/double-triggering-to-start-of-flow/136349)

Changed now all in my flows to be triggered by seconds as minutes made double (even triple) triggering (and resulted high load / HomeyScript trips).
