I choose Tyre Dog at the time, I'm guessing 4 years ago, because they were inexpensive and enough people said they worked on their cars.
I believe there's a high and low alarm. Our rear Honda CRV tires cold pressure is set at 39 PSI; the trailer tires are set at 50 PSI. We set the low pressure alarm at 35 PSI.
My tire dog monitor sets next to my ultraguage, both placed in the speedometer area of the Honda, neither is too large. I regularly glance at them. As we drive I can see the pressure and temperature increasing as the miles go by and the day's temperature increases.
We had a 'nail' flat this week and one of the Honda's tires beeped and flashed Lo P. I watched the pressure drop thru 32 PSI and knew we had a flat.
On really cold mornings the pressure sensor will go off because on cold days the inflated 39 PSI can become 35 PSI. However in a few minutes of driving the pressure gets above 35 PSI and the beeping stops.
It is also possible to defeat the fault beep which I sometimes do on cold mornings.
To read the temperature you need to push a button. I do it every now and then to see the trend, particularly if they're different from side to side. We did have a partial lock up of a brake once and the tire heated up and was visible on the Tyre Dog.
The fact that there's a 11 PSI difference between Honda tires and Trailer tires has not been a problem. (Admittedly we keep our rear and front CRV tires higher than most people who do not tow. I believe Honda suggests 26 PSI for non-towing driving. Our goal is to stiffen the tires hence higher pressure.)
All that said we have not looked at what's available in tire pressure sensors since we bought these. They have worked.
When we get a new tow vehicle this year we'll not need them on the tow vehicle because all new vehicles have tire pressure sensors.
