Why aren't these sensors mounted inside the tire, as a part of the valve stem, like in an automotive application? The battery in those is designed to last around eight years.
I think the manufacturers of these things are could design something better for us.

I use the EEZTire TPMS system which uses sensors mounted to the valve stems. The tire temperature I get from these sensors is completely adequate for the job - to watch for higher than normal temps as an indication of a pending failure. I can see the temps rise as I pull the trailer and even see the difference in temperature from the sunny side to the shady side. They work just fine.
