Hi Robert, welcome.

To which post you’re replying to?

When you responded to my [post](https://community.homey.app/t/flow-to-monitor-devices-and-notify-if-not-being-live/113510/2):

I suggest to discuss script issues in the topic of the script I linked to.

I’m over 664 months old 🤣🤣  
In Homey language, 664 months means, when no last seen value is found, it just returns 1-1-1970 as value.  
(No clue who came up with that date).

Also, _last\_seen_ timestamp is not always the real last seen moment

> That makes no sense thinking A “last seen” value is something that Homey determines. ( Repeater: “Hey Homey, you last saw me yesterday!” Homey: “No I didn’t, I’m seeing you right now!” Repeater: “…” )
