My 68 plate sportage tpm,s are very sensitive, one wheel dropped 1 psi, suspect due to cold weather and threw up the dashboard warning ⚠️ light. Anyone else have the same?

Never had that occur on any car fitted with TPMS. As the weather seasons change I adjust the pressures accordingly but 1 psi seems overly sensitive.
It's not TPMS sensitivity - it's Boyles Law - the tyre pressure will naturally drop 1 psi for each 6 degree C drop in temperature - some places have had a 12 degree change from last week to this.
I've had a few Kia, s and the tpms are very temperament. Had to increase a few 5/6 psi to get the dashboard warning light to go off & then a few days later lower to correct pressure. Very strange indeed
What you don't state is how close to the lower limit the tyre was before the temperature dropped.

When winter cold starts all tyres need checking whilst still cold and inflated to the correct cold pressure. Then in the menu set them. Unless it comes considerably colder no Tyre Pressure light should come on again. If they are just left at summer setting they are prone to come on until traveled some distance to warm the tyres up.

My fronts are 33psi per VW. Drop to 32 the warning comes on. Drive a while and back to normal.
We are told never check tyre pressures when hot🙀

Always do mine when the car has not been run, and there’s no sun on the tyres.
Mine are set to 33 all year round but a couple of days back the temperature was just below 2degC and the TPMS reported 31psi but no warning was set.
