linak-controller: Locking computer stops table from moving

First of all, thank you for this script.

I use KDE running on Manjaro as well as the Linak DPG1C. The script runs fine until I lock my PC. After locking and unlocking, executing the script produces the following output:

Connected EA:69:XX:CE:XX:9C
Height:  641mm
Moving to favourite height: stand
Height:  641mm Speed:  0mm/s
Final height:  641mm (Target: 1116mm)
Disconnected 

I have only been able to fix it by connecting the phone app to my desk, moving it a centimeter, disconnecting, and executing the script again:
