Namron Zigbee LED Dimmer 4512751

[Konstabel]

What happened?

The device is listed as supported, and it is no problem to pair and use the device. The problem is that after the fist command is sent to the device, it gets very unresponsive. It takes between 7-15 sec to turn the dimmer on/off or adjust brightness. If I wait 1-2 minutes after last command is sent, the dimmer is snappy on first command, then on second/third command it gets very unresponsive again. It also reports that current firmware on dimmer is 20, but last firmware online is 10.

What did you expect to happen?

That the dimmer is fast to respond to commands and that no error is reported when sending commands. Matching firmware on dimmer and "online".

How to reproduce it (minimal and precise)

Happens every time I use the dimmer (Except for the first command).
