filter duplicates out for outbound connections
I have a problem with my NMEA 0183 multiplexer where several devices are repeating values but calculating them slightly differently. This causes displays to jump around. I would like to come up with a way to use Signalk to provide a single filtered stream over both tcp and serial and have devices use these connections instead of the multiplexer outputs. This way the multiplexer is only responsible for the inputs and signalk is providing the input for all devices

Assuming everything has different 0183 “talkers”. You can use the path-filter plugin, node-red, or source priorities to get the data the way you want it in signalk, then use sk-to-0183 plugin to send that back out.
