Apps for phone NMEA 2000/ Wifi

[onesea]

Ok I have AIS and other boat data over Wifi, looking at other apps, primarily for andriod.

I am not thinking Navionics, Open Seamap, Qvtlm, Memory map etc

Looking at less main stream apps, I found this one:
A simple graphical customisable display:

NMEA Dashboard - Apps on Google Play

The one that would be nice is one that sends the data from one phone to another, allowing remote monitoring. I am thinking of at anchor or in port when on the boat but not with the boat. Depth heading position on map.

However any other useful apps, would be appreciated.

Is it possible to plug NMEA into my existing (4G) WiFi router? If I used a network cable from the NMEA bus to RJ45 on the router and opened a port would that work or do I need something to translate the data and send it to the router to make it visible over my own WiFi?

It seems a duplication to buy an NMEA to WiFi device and have to connect my phone or tablet to that wifi instead of the one that's already providing Internet access.

It depends on which version of NMEA.

NMEA 0183 uses RS422
NMEA 2000 uses Controller Area Network
NMEA OneNet uses Ethernet.

For the first two, you need to convert the physical signal to Ethernet and packetize the data. For the latter, you need to ensure that the routing is working correctly.

My knowledge is sadly outdated. Work and elderly parents have left little time for boating recently. However ...

The title of this thread is slightly confusing because the nmea dashboard app onesea points to uses name-0183, not nmea-2000. Or rather the application layer: As st599 points out above, the nmea protocols were intended to be transmitted over wires but people started taking the data out of nmea-0183 (which had a well-documented structure despite being the super-secret intellectual property of the nmea) and transmitting it (without any particular standard) over wifi. Just about all applications I'm aware of which use "nmea" data over wifi use -0183. I don't know of any which use nmea-2000 data: it was less well documented (there seems to be more open / reverse engineered documentation around now than when I was looking at this a decade ago) and there's a bit more information the underlying datalink layer that might need bundling with the application data than is the case with -0183. Raymarine's SeaTalk-HS was (I believe) essentially n2k-over-ip but of course it's proprietary.

You don't say what "bus" you mean but the answer is no, unless you have an nmea (some flavour) -> ethernet (rather than wifi) device. If you're talking about a Raymarine seatalkHS network, "no" because I'm not aware of mobile apps which talk seatalkHS (and @RobbieW has some experience with what radar data can do to your wifi). If you can't find an nmea-to-ethernet converter to plug into your router, then get an nmea-to-wifi device which will work in "station mode", ie as a client of an existing access point rather than creating an access point itself and making you join it

[Edit] clarification:”nmea2000 to WiFi” Devices which I was aware of generally work by converting to -0183 first so they can’t transmit the full range of information that NMEA 2000 can. Perhaps that’s the source of my confusion around the title vs content of the original post

My yacht devises wifi gateway has built in HTML configurable instrument pages. No need for any other apps but I do use Imray Instruments sometimes as I got it many years ago.

Anybody have an idea to see the NMEA 2000 data via WiFi, any idea? Currently I have Axiom7 and a few other NMEA 2000 equipments.
