Consider it, your are Deutsche Telekom, you release the Magenta System, do you want to put any effort to support any 3rd party device, but the ones what you sell. Of course not…
That’s why you would support the -D and not any other.
ZHA and Z2M is not interested about what is the identifier of the device when it is executing the assigned code, you can list as many identifier for the same code. Z2M has in the herdsman converter both the 3400 and 3400-D listed for the same code.
Or just as an other example centralite has 3200 smart sockets, a de and fr version, both has the same code in the herdsman converter.
I finally found the way to make the keypad beep on command.
It is done by issuing a panel_status_changed zigbee command on the IasAce cluster.
Here is the YAML, make sure to swap the ieee id with your keypad’s id. You can find it in the device info menu. The seconds_remaining parameter determines how many times it beeps.
