in the GUI we see lightning actions:
what actions are these and how can we use these?
these actions are not described here:
https://www.velbus.eu/downloads/velbus/00_general/guide_velbus_actions_descriptions_en.html
where can i find some info on these?
This is correct, we haven’t updated that page with the edge lit actions.
You can configure “lightning” actions (17xx and 18xx) and specify the priority (low, medium, high) with each action as a parameter. The subject of the parameter has to be VMBELO > Module actions.
Please note: There’s a bug in the current VelbusLink version which affects these screensaver options. We’re working on it to solve it in the next VelbusLink version.
If you have questions about a specific action, while the action page isn’t updated, don’t hesitate to ask.
