Automation triggered when Homey goes offline/online

I do understand the use case. I also think that I understand when you write “Homey goes offline”. The WLAN/LAN connection of Homey to the home network is interrupted, correct?
I don’t have any of the “Net Scan” apps mentioned so far, but I assume that they only monitor the internet connection of the home network, or other devices that are connected to the home network. The WLAN/LAN connection of Homey itself is not monitored by the apps.

That was also the reason why I mentioned G. Dijker and his sysInternals app. This app monitors the WLAN/LAN connection of Homey itself.
Maybe you should ask in the appropriate app topic if this function can be added:

[APP][Pro] sysInternals - Shows Homey’s System Internals

That’s right. But what if he or other users use WLAN devices?

So the request definitely makes sense to me.
Example flows:

When…
– Homey goes offline (WLAN/LAN!!!)
And…
– Timer, stopwatch, transition is running
Then…
– Stopp timer, stopwatch, transition

When…
– Homey goes online again
And…
– Timer, stopwatch, transition is paused
Then…
– Then continue timer, stopwatch, transition

Btw, how is the HP23 connected to the home network? Via WLAN or LAN?

However, I also recommend to contact the support.
