Upgraded my server to the last stable version and having similar issues. Most of my http device are "not found" and a least one returns the following error :

Devices : 07/11/2019 22:52:54 : Error : Devices\Meteoalarm : Error connecting to device. Misused header name. Make sure request headers are used with HttpRequestMessage, response headers with HttpResponseMessage, and content headers with HttpContent objects. at System.Net.Http.Headers.HttpHeaders.CheckHeaderName(String name)
at System.Net.Http.Headers.HttpHeaders.Add(String name, String value)
at ComfortClick.Http.Driver.HttpDriver.d__10.MoveNext()

Strange wise, some other having headers data too don't return anything.

The most annoying is that all devices are not functioning anymore! For info, the last most stable version for http device was Beta version 6.14

Hi Dieter,

I recommend to go to Beta 4.6.14, much more stable as 4.6.15 (had to roll back). I experience lots of Basic and Http device disconnection with the latest Beta. However, KNX is fine for me.

As a side note: for my configuration (KNX router on my intranet) I had to set "NAT=false" to get my KNX connection stable. 


Hi Jurgen,

Reading your post I went and check my Grinder. All good there as bOS service is running @ around 1%. Last full reboot was several weeks ago, but I installed the lasted Beta only few days ago... Unfortunately I didn't check with v4.6.1 but will try to reinstall it when I have time to see if there is an impact on the CPU load.

Hi Marco,

Create a program instead... you will then be able to set the days but using "if" instead of "or".

Hi Stefan,

You can access the logs by clicking on the bottom left corner :

Top ! Nice to see you like the solution.

Hi Jürgen,

Happy to read it works by now.

I've had similar issue as your "0 heading" one with some of my API. The only (somewhat heavy) solution I found is to to create a program to set correctly the propertie. The goal is to get rid of %6 and have the following done for %0,1 and 2:

if General\Time.Value=1

set Devices\Http ENTSO-E test\Corrected Time.Value=01

if General\Time.Value=2

set Devices\Http ENTSO-E test\Corrected Time.Value=02


if General\Time.Value=9

set Devices\Http ENTSO-E test\Corrected Time.Value=09

%0 propertie value would then be linked to Devices\Http ENTSO-E test\Corrected Time.Value and so on.

Of course you can put the node name of your choice ;-)

This should solve your issue.


Try with the below, having propertie %5 = 0000. Don't put the ' character around %x


If the file host url is set, the command should most probably be /api/meters/aggregates

I hope this will help

Di you try to repair or reinstall the server already ? Had similar issue after installing one of the very first beta version and could fix them after reinstalling all from scratch.

Still few issue exist, but nothing that makes bOS unusable for me. All are cosmetic error and unnoticeable during normal use (can only be seen in the configurator).

Hope it will fix yours.
