Reset KNX device without ETS

[Trond Hoyem]

This feature will be available in the next version

Code:

knxlib.restart('1.1.100')

Where can I find this version? I upgraded to the version posted here; https://openrb.com/firmwares/

But when I use this code in the LM I get the following error:

User script:24: attempt to call field 'restart' (a nil value)

I have used the code in SL several times, but this is first time in LM.
