KNX number platform reads value from bus without state_address configured

Description of problem:
I have a couple of knx numbers for which the value is calculated outside the KNX bus. The value is sent from HA to the bus. For all of those KNX numbers I have not configured a state_address. However, when restarting HA there are GroupValue_Read messages on the bus. I would have expected that in that case there are only GroupValue_Write messages from HA, the restored value.

  • using xknx standalone
  • using Home-Assistant knx integration

Version information:

  • xknx / Home-Assistant release with the issue: HA 2022.10.4
  • last working xknx / Home-Assistant release (if known): ?

KNX installation:
I assume this is not relevant.

Problem-relevant configuration.yaml entries (fill out even if it seems unimportant):

- name: nr_gaezi_stellgroesse
  address: 4/7/15
  # state_address: 4/7/15
  type: percent
  respond_to_read: false
  min: 0
  max: 100
  step: 1.0
  mode: slider

Diagnostic data of the config entry (only when Home Assistant is used)

Traceback (if applicable):

Hi 👋!

Try enabling debug log level for xknx.state_updater and see which exact device is scheduling the read request.
The output looks like this then:

DEBUG (MainThread) [xknx.state_updater] StateUpdater registered StateTrackerType.EXPIRE 60 for <RemoteValueSensor device_name="Luftfeuchtigkeit Außen" feature_name="Value" <None, 6/6/5, [], None /> />

Just grep the log for the group address then.

Thanks for that hint. It is the climate entity that is requesting the value from the bus (command value), not the number entity. I haven't thought about them. I will close the issue.
