Read Request to KNX

i´m on latest snapshot version of OH 2.2

I use knx binding. One of my knx-devices only sends data, when it makes an action. So when i restart openhab (without persistence) i don´t get the knx status of this device until the next action is done by the device.

Someone told me, i can send a READ-REQUEST to the KNX Device, in the ETS it is working.

How can i do this in openhab? If the status is shown as “undefined” in openhab, the read request should be done.

Can someone help me?

Just put the minor sign “<” in front of your group address. This queries the state at system startup.
