Any ideas how to debug this? Many thanks!
Sentence looks OK in nmea checksum calculator
https://nmeachecksum.eqth.net/
Command:$*
With checksum:$IIXDR,P,1.0155,B,Barometer*17
Mine is the same, assumming it's because signalk creates a XDR nmea0183 sentence, not a MDA sentence, which is obsolete apparently >>
https://opencpn.org/wiki/dokuwiki/doku.p..._sentences
"MDA
Meteorological Composite (obsolete) This message is obsolete and NMEA recommends to use XDR transducer messages instead. However, old instruments might still sending this message."
Maybe more of an Opencpn question than openplotter.

Or probably possible to do a hack in node-red.
Thanks for the confirmation. I re-posted in opencpn forum in case anyone knows a quick fix. (I don't know at this stage how to hack the node-red...)
