@Jocala : can you try 433.92M
instead of 433M
from rtl_433.
That's not an error but just a waring that noise looks like data and then exceeds the reasonable amount of data to read.
Perhaps levels are not ideal. Add -Y autolevel -Y magest -M level -M noise
and check what noise and level readings you get.

I'm obviously a noob, thanks for looking at this.
rtl_433 -Y autolevel -Y magest -M level -M noise -H 120 -f 433M -f 915M -C customary
With this command-line I get:
[Auto Level] Current noise level -2.5 dB, estimated noise -2.7 dB
[repeats]
[Auto Level] Estimated noise level is -27.5 dB, adjusting minimum detection level to -24.5 dB
[Auto Level] Current noise level -27.9 dB, estimated noise -27.9 dB
[repeats]
First transmission received:

RSSI : -12.9 dB

I never see a transmission from the LaCrosse-TX141THBv2.
from rtl_433.
A noise level below -20 dB is good, that noise level close to 0 dB is a jammed band or recpetion problems.
What change do you see when hopping occurs? Use -v
to get hopping notifications.

[SDR] Tuned to 433.000MHz.
[Auto Level] Current signal level -2.1 dB, estimated noise -21.9 dB
[Auto Level] Current noise level -2.1 dB, estimated noise -2.4 dB

[Auto Level] Estimated noise level is -16.6 dB, adjusting minimum detection level to -13.6 dB
[Auto Level] Estimated noise level is -18.0 dB, adjusting minimum detection level to -15.0 dB
No transmissions from 433Mhz noted when both -f 915 and -f 433 are used.

Calling this a probably answered question, unless the submitter would like to respond/restate/etc.
