Online / offline notification

Hi,

How can i change the notification message (online/offline )

Thanks

hello,
I’ve a raspberry 0 with openhab 2.2 installed on board. I can connect to it from internet trough the cloud and all works quite fine up to now… in “https://myopenhab.org/notifications” I can see all the times my openhab goes online/offline. On my mobile I have installed the openhab app. From the cloud in “https://myopenhab.org/devices” I can send messages to my mobile, but I can’t receive any notification when my openhab goes online/offline. How can I solve this issue?
