I'm not the module developer, but I'll try to explain based on my
understanding.  The "unmatched incoming data_chunk" reflects an
inability of the (presumably RF receiver) parser to match received data
with expected patterns.  In virtually all cases where I've seen this
occur, there was marginal signal strength between the transmitter
(presumably, a motion detector like a MS13A?) and the receiver.  For
example, if you happen to have aluminum siding, then use of wireless
detectors outside can be quite challenging (assuming your
receiver/antenna is inside).  If the received signal is marginal, then
moving objects (like people) can sometimes be enough to further lower
received signal and distort the interpreted data.  Also, some receiving
devices do a poorer job than others.  Searching the archives will
suggest various individuals' experiences w/ RF receivers.  Lastly, other
sources of RF interference can be a culprit for localized problems.  I
once had a leaky RF pre-amp that created such a problem.

If you consistently get the unmatched incoming data_chunks for only one
(or few) of your detectors, then try moving the detector and/or
receiver.  If you get this a lot, then try turning off possible sources
of interference or possibly upgrading to a better receiver/antenna.
