Hi Mark, have you solved your problem in the meantime ?
I have the same problem with very similar hardware:
Arduplane 4.07 using the same configuration as described by you.
Matek H743 Wing
Taranis x9d plus se 2019 with OpenTX 2.3.10, yaapu script is showing up but has no data
Taranis did not found new sensors after script installation
FrSky Archer RS using ACCESS, Fport and Fport2 enabled
Beside Ground and 5V I connected the SPort directly with RX6 as described elsewhere.
Servos are controllable with this wiring.
I have no idea what I am doing wrong.
What I did and it did work at the end is, that I just flashed FC with same firmware. Somehow if wored with same settings.
For some settings that I saved in Mission Planer were not working afterwards, but worked after I saved them with QGC.
I got GPS, artificial horizon and airspeed on the remote. But no message, voltage etc. At the end I switched to TX16S. It was just too many problems in general with remote.
you saved my day
I tried what you said and it looks like it works. Now Taranis can find the sensors after a fresh search and Telemetry-Screen shows several values.
Thanks so much for your help and also thanks to Mark for giving feedback!
For all pilots who have similar hardware:

It worked for me with the following settings in arduplane:
