Hi there!
First of all - i really like the nymea system!!!
Maybe its possible to integrate a popup message in Nymea:app kiosk, like already exists with nymea cloud -> push message, but now for the other direction.
Perfekt would be the integration in two ways. First - a popup message (triggerd from a rule) is shown in the middle of the screen for very important messages. This Message need a click at a “OK”-Button to hide it.
Maybe a second very usefull popup message in the lower right or left corner, that shows a message for a short time period (configurable) and hide automatically and can be stackable if more than one message is shown.
All of this messages should also activate the Display.
Does it sound realizable?
Thank you so much for your great work!
