This is how I track my pressure with FOBO bluetooth sensors. They have 2 versions, with and without a temperature sensor. So, if you shop, make sure you compare the right models price wise. I have gotten mine from Amazon.

My use is to take a phone out and read all my bikes pressures, since the app scans all sensors, and my bikes are parked near each other. So, one single source of all my bikes pressures. I also have a bluetooth gizmo for my battery on every bike (a different product whatsoever from a different company), so, I read with another app the main's battery history of voltages. So, this is my routine like once a week, every day things don't change, unless there is a temperature dip. If you run the app all the time, you can get warnings of low pressures, I don't. I think if there would be a blow out, you'd know, if there would be a slow but steady leak, I'd see it in my checks or would feel through the bike handling.
I think the sensors for this price are good - sensitive, as the fractional part of the reading does go down logically, so I assume that the sensor can read the pressure to the fractional part fairly accurately.
I change the batteries for each sensor about once a year, maybe year and a half. The app shows you the battery status.
It is an inconvenience to take off the sensor to add air, yeah. Some people have installed (for other bike models) a T, where the sensor is attached to one side and air can be added to another side. But it requires taking off the tire, and some air nozzle assemblies are very specific to the rim, basically, you can't get a T for said rims. After taking off the sensor to add air a number of times, I think I can do it nowadays without much thought put into it.
