The Stinger seems to do the same as Vyper regarding the temperatures (no
pressure support) but my wife's D4 records the temperature every hundred
seconds or so it seems on the logs.

I didn't even realize that they were air-integrated at all. At least

Seems that currently they are selling wireless pressure transmitter that
fits  Vytec-, Hel02, Vyper air- and D9 models.

 The jdivelog file doesn't seem to have those pressures, though - at

Manual entered data sounds plausible.

Yep, the pressures in my samples are manually entered as my computer does
not have any air integration. (Inserted as 220 to 80 bar as suspected.) So
nothing can be deducted from my samples regarding how jdivelog handles
pressure. Except for the pascal unit.
