I have couple of qubino dimmers zmnhdd and in one of them i use i2 input to control scenes in pulse mode. During last month, the scene triggered itself twice. Not by the button press. By scene I mean that the dimmer channel corresponding to i2 input was changed. So unless there is some weird bug in my items/rules files, the dimmer device sends status changes to the controller by itself. I experienced similar behaviour with some philio zwave switches and and found the solution to put diode between switch input and the live wire. So does anyone experienced similar issue with qubino devices ?
