After many many hours I finally found this website: http://support.betaalbare-domotica.eu/how-to-use-wallc-s-remote-controller-with-ui7/
And when you follow this instructions it works 100%. But that was on a Vera Edge of a friend, with his wallc.
On my Vera Edge and my wallc controller, something strange is happening. Buttons 2,3,4 are working fine.
As described you should use scene 0 when a button is pressed and that’s indeed the case with my friend. All buttons generate sl_SceneActivated=0 in the logging (used tail -f). But when I look in my logs, I see different numbers for sl_SceneActivated.
When I push button 1 once (id) 11, I see sl_SceneActivated=5. So indeed button 2,3,4 are working as the use sl_SceneActivated=0 and so the scene is triggered. When I add a second device trigger in the scene, (trigger it on sl_SceneActivated=5 also) I can use button 1 too.
With that I see that sl_SceneActivated=7 when I push button 1 twice.
So, I hope someone can help me out, why button 1 does generate different sl_SceneActivated numbers. They should be 0.
Some extra informaion: Replaced the wallc with an other one, did factory reset on the wallc. Exclude/include several time.
