Port switching randomly on SLESA-U8

[gma222]

Hello,

i bought 2 years ago a SLESA-U8 Vers 2010.
i use it to control my home lights using the ports. I connected a push buutton on the port system and therefore can use different scene by clicking on different buttons.

All this works great, except that for a couple of months, the scene are changing automatically and randomly.
I can be on scene 2 and it will switch for scene 3 without any reason I understand.

I did not use the time trigger or any other fancy option. I updated to the latest firmware but that did not help.

Any clue?

I think the best way to find the problem would be to disconnect the port buttons for a few days and see if the same thing happens
