alexa not responding

Adi Shamir 2 years ago in Devices / KNX updated by Jürgen Jürgenson 1 year ago 16

Hello, I have all my KNX devices at home connected via BOS to Alexa - about 70 devices. All worked well, until suddenly Alexa stopped responding to all devices. i.e. - When I ask Alexa to 'turn on' a device, it says that the device is not responding - this is the same situation with all my KNX devices. To clarify, BOS works well from the app and also Alexa works well with other devices not connected via BOS. Any idea?

Are there any fast way to input status adresses when importing from KNX or is typing them in manually the way to go?

Thanks in advance.

KNX connection type resets after reboot

Noel Fuentes 1 week ago in Devices / KNX updated by ComfortClick Support 6 days ago 1


After upgrading bOS to the latest version (4.8.20), when I reboot the server (a clean reboot: Building/Reboot), the KNX conecction type sets itself automatically to KNX IP. I change it to KNXnet IP (Falcon), but with a new reboot, it changes back to KNX IP.

Is anyone experiencing this?

Best regards,

Hi Ad,

I'm learning the connection between a bOS and a device with KNX protocol.
How many devices can the bOS be connected to via KNX?
If you have a sample configuration of bOS and KNX device, please share it with me.

Thanks & Best Regards.

Date and Time capturing to pass on KNX bus

Paul G 4 months ago in Devices / KNX updated 3 months ago 7

There are a couple of similar posts, but none really hits the nail on the head as maybe I have a different problem. BOS server version latest 4.8.14 

The situation is very simple, I want to create three variables (date, time, timestamp) in BOS, which are then mapped or given the same addresses as KNX so BOS effectively populates the KNX addresses and issues the date and time to the KNX BUS. However, there are continues issues, despite several and lengthy testing performed

Current BOS variables created

Current KNX variables created in ETS5

Time, seems to be working fine


  1. First problem, the value type, KNX 11.001, allows for the time, but the time value is actually not populated by BOS
  2. Second problem, if status address is populated in the BOS variable it creates problems for BOS and the date is no longer transmitted/populated
  3. Third problem, the associated KNX variable, spits errors, despite being the same value type

BOS variable

KNX variable

Errors spit in transforming


  1. First problem, the time is not populated, only the hour of the time is, minutes and seconds are not populated
  2. Second problem, the KNX variable is not populated, not a single field
