I have wandered down a rabbit hole trying to get barometric pressure to display on my chartplotter. Yes, there are mechanical barometers available. Yes, I could use my phone for barometric pressure. Yes, I could just quit screwing around with my device and focus on fishing. However I'm $100 and many hours into trying to resolve an issue that apparently requires a $200 NMEA 2000 gateway (if you don't know what that is, you may stop reading at this point).
The gentleman in Russia who sold me the sensor suggested I borrow one. Does anybody have an NMEA 2000 wifi or USB gateway I could borrow for a few minutes?
