1) Source; S = Shaft, E = Engine
2) Engine or shaft number
3) Speed, Revolutions per minute
4) Propeller pitch, % of maximum, "-" means astern
5) Status, A means data is valid
6) Checksum

I'm little confused. When I use emulator and the data comes from nmea183 and it is passing thru SignalK to the TCP connections - all is ok on the QTVLM - RPM works. If I connect my Engine HAt who produce only SignalK sentence to Signal K serwer RPM on QTVLM - no works. What is wrong? I think SignalK serwer not decode from Signal K to nmea183 ... ???? Mayby there is some problem with SignalPaths. When I have path tanks.fuel.A.currentLevel - Open CPN dont recognise them. But When I put tanks.fuel.1.currentLevel all is Ok. I mean engine dashboard not DasboardSK - In this we can choose paths

This issue just marks that ”somebody should implement RPM” it is not supported yet.
