Read Homematic system variable immediately

Third party integrations
1

Hey
I have a CCU3 from Homematic and connected to Home Assistant via the “Hommatic(ip) local for openCCU” integration. So far, everything works fine.
I use some processes in the CCU3 that I would like to keep there.

According to the integration description, the data between Home Assistant and the CCU3 is updated every 30 seconds. This means that the content of the entity in HA changes with a significant time delay.

Is there a way (e.g. automation, yaml-sequence) to update this system variable in HA without a significant time delay?

Are you sure about this? My experience is that entity states are changing without noticeable delay.

Yes, it’s about changing a system variable. The status of a switch or button is transmitted immediately.
In HA, I placed the status of a virtual button from the CCU3 and the content of a system variable side by side on a dashboard. It takes about 12 seconds for the system variable to change.

Hhm, I use Homematic only for the sensors. Anything else is handled within HA, which I find much easier to organize.

I would think that it depends on what device class this variable is getting in HA. But I have difficulties understanding what you are doing (and why).

Thank you for your support.
I would like to explain it a little.
In my CCU, some programmes run a fire alarm process and a intrusion protection process. To avoid risks due to interface problems, the important components of these processes only run in the CCU. The processes are controlled by changes to system variables.
For more convenient operation, e. g. voice output is also provided on the SONOS system. These are easier to control in HA. If there a problem with the interface, it isnt so serious. I wanted to control HA by changing the system variables, but I cant use a delay of 12s. However, I have now solved the problem by assigning the different states to a button on the RCV-50. This button press is transmitted immediately and an automation controls a helper.
I can live with that.
