Meaning of the error message "HomeMatic device communication disrupted"
An error message often pops up out of nowhere with a smart home system. It can help if you know why they are actually displayed.
- Device communication error messages are always displayed when the CCU does not receive a response from a device.
- A distinction can be made between the variants "communication is currently disrupted" and "communication was disrupted".
- "Communication is currently disrupted" is displayed until the CCU receives feedback from the corresponding device at some point. In this case, you usually just have to wait a little.
- You will then receive the message "Communication was disrupted". You have to confirm this, otherwise it will not be deleted from the list.
Avoid the message "Homematic device communication disrupted"
Often the problem of the error message solves itself. However, if you keep getting the message, you should look for a solution.
- Check whether the device is operating reliably and whether there is a radio connection to the CCU.
