Hi, I read in the Homey IOS app release notes “_Added a last-seen warning for devices_” (version 9.10.1)
Can anybody tell me where to find that in the app, or how to use it?
I know I can find it in the “homey developers tool” website, but that is not what is suggested here. Thanks!

I incidentally get a notification in orange at the top of the mobile app, when opening a tile of a device that apparently has not communicated with Homey recently. That might be the warning you are referring to.

Thanks! Any idea what “triggers” this? Is it a time out (device not seen) longer than the LPI (Long Poll Interval)?

I have no idea 😊.
Also I am not sure what the purpose of that warning is. The few cases I received that warning, the device was still operating normally.

Maybe it’s an alert about the last state or about the current state?
I presume a timestamp (`last seen`) lacks?

Yes, indeed. Unfortunately I did not make a screenshot of the notification 😊.

I’ve never seen that. Is it only on Pro2023/26?

Can’t answer that, as I haven’t seen it either (yet)
I was triggered by a comment in the IOS app release notes.

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:
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.

@SunBeech Nice. Wat handling made the message appear?

I do have the beta app, but I use Pro2019 so it probably only shows on Pro2023/26. Or it is a custom warning from that specific app (you can also set messages with `setWarning()` from within the app, I use this for displaying faults from the device in my Duux Gen2 app for example).

The only thing I did was open the device tile in the mobile app.

Might be, though I saw exactly the same message for some other devices (not Sonos) in the past weeks. So I think it is a Homey OS message; not an app generated message.

In the meantime I have seen some reporting (like shown by Sunbeech) myself, when I click on a device. I noticed that it cumbersome, and often wrong.
Devices not seen for a long time, are normally online.
And clicking devices one by one is time consuming.
For Zigbee I prefer the _Homey Developer Tools_ page instead, I shows you in one page the time for “last seen”
