Funny, my car did this over the weekend, after sitting idle for about 10 days. Pressures were within spec, but displaying as needing attention. I took it to the dealer (you can drop in and have tires adjusted gratis), and they just reset the display, hasn’t returned since.

It’s because the temperatures are dropping here. Mornings are in the 50s now when I leave for work, so the cold tires are down a bit. That front right is at 34 cold.
I haven’t put air in the tires in months, but I’ll top them up when I get gas - the sensor will reset itself when I do that.

That’s way more than a half PSI. Be careful or you'll roll it!

It’s bound for the crusher. Because I’m your friend, I’ll take it off your hands and save you the trouble.

You know what you need? A digital tire pressure gauge.

I’m really lucky I haven’t jumped a curb and wrecked it yet.

That’s about as cold as it is getting here too, for now. I found it funny that the readings were still within spec yet generated the alert - but maybe the decrease set it off. I’ve h ad the car for nearly 6 months now, no air added yet, but our temps are n’t as variable as yours.

Yeah,
our
low
temps
were
in
the
70s
for
part
of
the
summer.
Makes
a
difference
Temperature drops always cause these alerts to go off in any TPMS vehicle I’ve owned.

My PSI looks like that when my vehicle has been parked partially in the sun, the tires in direct sunlight will be a few psi higher than the ones not.
Just a little tip, inflate your tires a little over, then in the morning before you drive, adjust them correctly.
