Keep the forum informed. I think other people will want to know the results. Securifi may be able to help if there IS an issue. One thing I would recommend:
After pairing, try each available feature. Then send logs saying what they are for (the Tradfri) and finally post on here (this thread works) saying how it worked (or not) and reference the log name. That can all help Securifi and other users. I think mparadis made a sample "new sensor" post that has all sorts of useful information that could be listed.
