Right. With the help of Qubino support I have solved how to get my input I2 working on a Flush 1 Relay. Maybe it is useful for the other relays and dimmers as well. I had already set the parameter 100 to 9, excluded and included again. And I set group 3 to 1.1, being Homey. But switching input I2 gave no result in flows, but did in the log. See above.
I send the log to Qubino and this was the answer:
When you activate the I2 or I3 exclude and include the device, the mode of communication is changed from Single Channel to Multi Channel, if the gateway don’t set that you have to do it manually.
They added a Gif on how to do it in Fibaro, but on Homey you just need to set Group 5 also to 1.1. For I3 it will probably be groups 6 and 8.
Hope this helps with the dimmers as well!
