I need to use logic in a Loxone miniserver to activate different scenes based on how long a button is pressed and held. The lighting scenes are set up in DALI controllers that respond to KNX/EIB scene numbers on a set of group addresses. When setting up buttons that write scene numbers directly to the group address the scenes activate as intended. When attempting to write scene numbers to those same group addresses from Loxone nothing happens. I have tried different types of formatting for the value to be written to the addresses, such as :1 , :1! and :1#
The attached screenshots show:
1: Button on panel with adress 1.1.6 writes scene number 2 to group adress 1/1/1, this makes the scene execute correctly
2: Second button on panel with adress 1.1.6 writes bit value 1 to group adress 1/1/9 which acts as input to Loxone. Loxone (adress 1.1.249) sends a telegram which appears to be empty, there is no payload displayed. This telegram is sent to group address 1/1/2 which is meant to activate a scene.
