Remote temp sensor

Where did you find your "indicators"?  Were they expensive?

The only pressure monitoring device I was aware of, were the ones that clamp inside the wheel (when changing tires) and transmit a pressure signal while rolling.  They auto-shutoff when stopped for more than a few minutes.  Battery life of sensors is about 3 years, but the system is three or four hundred bucks!

Too rich for my blood.

But I wouldn't mind a little extra "low tech" insurance...
