Hello and welcome, Dexter, ![Screenshot_20240509-164546_Chrome](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/b/4bd396c961f1afd7f879dec478875ee428729e44.jpeg) In most triggercards, you can’t use a variable as value, but as you’ve noticed, there’s no warning and the card can be saved. I prefer to use a Chronograph timer: - You can use a numeric variable as timer value - It survives a power outage / Homey restart Example > [@The Flow Exchange(r) - Exchange Your Flows with Others!](https://community.homey.app/t/the-flow-exchange-r-exchange-your-flows-with-others/68981/8): > > ### Flow example: > > ![Screenshot from 2022-09-21 00-48-34](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/a/2aa742727e50bc75f1e9b207663d1b8b84560c32.png) . > [@DJG3](#): > > is there an official known issues log maintained by homey that lists which “native” features are broken with Homey Early 23 so I can avoid using them? Not to my knowledge. You happen to have used an invalid input method. Pls write to Athom support why there’s no warning / why you can save the card (homey.app/support). --- _[View the full topic](https://community.homey.app/t/zone-inactive-for-x-minutes-doesnt-work-with-variable-how-to-troubleshoot/109598)._
