KNX sending sensor values not working

1

Hi, my KNX / Home Assistant installation is running without any issues. All data can be read, and the interactions work as they should. KNX Secure with the Secure Dummy is being used. Several IP routers are in use.

Now I want to send a temperature value onto the bus, but it simply doesn’t go through. The command looks as follows:

action: knx.send
data:
  response: false
  address: 18/3/0
  payload: 20.0
  type: temperature

However, it just doesn’t appear in the group monitor.

If I send a 1 or 0 to a switch address, it works without any problems. I’ve already tried everything, but I just can’t figure it out.

Thanks, everyone.

Hi :wave:!

Are you referring to the HA group monitor? Are there any errors shown in your logs?

3

No errors in the log. In the Home Assistant Group Monitor everything looks good, but in the ETS Monitor are no incoming telegrams.

4

Then I’d guess it is some kind of router filter table issue. Or DataSecure issue, but I think this would at least show in ETS group monitor.

I thought so too, the correct group addresses are listed in the filter table. I also re-imported the KNX keys. As mentioned, it’s strange that 1 and 0 as switching commands are sent through via knx.send. Is there a setting somewhere that prevents ‘larger’ telegrams? MDT IP routers are being used.

Have you tried to use ETS group monitor with routing (select the network adapter) instead of tunneling? If you can see the telegram then, you should contact the router manufacturer support.

Edit: this is when HA is set to use routing, if it uses tunnelling, that doesn’t apply.

7

Yes, all set to routing. Run out of ideas. :confused:

8

And you don’t see it with ETS running in routing mode?
Or Wireshark if you like…

Oh my God, two mistakes on my part. First, a typo in the configuration file, and indeed the telegrams were visible in the ETS routing mode. I was on a different VLAN, so I was connected via tunneling. Everything works now, the error was in front of the device. Nevertheless, thanks for the help, it was really helpful!
