It was a phone AP based system that will alert me thru my Sena headset
It uses the valve cap type sensors
Their are many other brands still available that use the same type sensor
To make inflation easier I installed T stems from Cyclemax
They are a Gold-wing parts House

The T stems work very well but require the flange be tapered and the OD be reduced to fit down into the countersink in the wheel
This is very easily done by chucking the stem in a drill and spinning flange against a file
