IKEA remote 1524/1810 buttons issue

[gschmidt]

Hi,

With zigbee2mqtt I added an IKEA remote 1524/1810.
I installed the zigbee2mqtt plug-in for Domoticz.
The remote shows up in the device list.
When I add e.g. the ON/OFF switch of the remote to Domoticz, the following happens:

1. When I press the physical ON/OFF button, the switch in Domoticz is responding with On or Off.
2. When I turn on the Domoticz remote switch...nothing happens...???

Also for the other buttons of the remote
Looks like one way communication.

Why is this?
