How to control the KNX bus via SMS and send notices via SMS?

[EjvindHald]

Check System config > Status > System Log and System config > Status > System status > Serial ports. What do you have there after LM starts?

Disable the SMS script and run this, then post what you get in Logs: https://forum.logicmachine.net/showthrea...0#pid34700

Thanks for your reply. I have tried your suggestion, but unfortunately I do not know how to enclose a screen copy to this post. Instead, I am writing the response in text.

System log
After a reboot it wrote that GSM modem was detected. And after that several lines in the log on the same second where it states "...now attached to ttyUSB0" and continue with several connection until stopping at "ttyUSB4".

Script log - newest at the top
Network: Greental (which is my mobile operator)
