Number item and percentage

[rossko57]

Okay, so that’s straightforward, it’s just a number channel, that’s what the KNX channel gives you.

I think you should be using a Dimmer Item and dimmer channel for that DPT? (or rollershutters)

Read value from KNX heating actuator

Unfortunately the KNX binding maps 5.001 to PercentType which is only accepted by Dimmer items. The only solution within openHAB is to use 5.005 and adjust your rule to accept 0-255 instead of 0-100. You will not get a percentage value because Units Of Measurement is not supported.
