Yes, I use one for my doorbell and it work's fine.
I do also have those random ON's on the other input, luckely not on the one that I use for my doorbell.
For your doorbell, are you using 220Vac or the option to power the device using 24Vcc: Latest would be more secure as this avoids dangerous voltage on your door-bell switch.
On my side, I use ZMNHND1 (dry contact) version for my horman garage door: Relay in // of local pushbutton command + I2 getting the door locked info (0/24V). As 24V is used internally by control board, I used an option connector to power the qubino (exact same 24V as lock info, so no level problem).
When I ordered the device, seller told me I2 was not reporting data correctly in his testing. In my application, this is working correctly.
So I suspect using 220Vac feature may not be working, but using 24Vcc, it is.
Other option may be firmware modifications by qubino for newer devices that may have broken the feature as many problems shows-up with qubino firmwares last 2 years (I have a smart-meter that was a pain in the a.. with buggy external relay control + some measurements reported as parameters: why the hell are they doing such stupid thing???).
