The log looks much nicer now. Thank you.
Funny thing is that your second DECT 210 device seems to support temperature measurements whereas your first one does not.
First of all I suggest you to upgrade to the latest release. The binding requires some features which are now available in the stable version. After that uninstall the AVM FRITZ! binding, download the *.jar file I have linked in my PR and put it into you addons/ folder (see openHAB on Linux | openHAB).
If that works you should add the DECT 210 devices manually in Paper UI. In the same way you did before. I will cross my fingers that it will work.
