“Device not seen for some time”

[FKey]

I am getting this message when I open my youless device.

“Device not seen for some time”

But (as you can also see in the screenshot) it reporting nicely (just seconds agoo)

Any ideas what can cause this?

I get that message incidentally when a device has been offline for a while (like a powered down Sonos speaker) while opening its device tile.

Where to find the "last-seen warning for devices"

I was lucky, I went through all my devices and remembered that one of my Sonos speakers has been turned off/powered down for a few days: [IMG_6181] See the orange message. In English it reads: This device has not been seen in a while. Check if it is powered and still connected. Note that this is on a Homey Pro 2026 with the beta v10.0.0 mobile app.

Maybe your watermeter did not report for some time, before the indicated update a few seconds ago, and the warning message is not cleared.
