Thank you to all that helped contribute to the OS Driver for Sevcon!
I have a Sevcon Gen 4 Size 6 on my EV Sailboat. It was a piece of cake to setup the Boat Page (per the gethub instructions), and it worked right off the bat with my Mk1 CerboGX.
I was really hopeful that the CerboGX would broadcast motor RPM over NMEA2000 so I could display RPM on my B&G Vulcan charplotter at my helm (I believe it is NMEA2000 PGN 127488). I already have current and voltage displayed via the NMEA2000 cable connected to my CerboGX.
Is it possible to accomplish this through NMEA2000 with the CerboGX?
It is indeed possible to forward the data from your Sevcon onto your NMEA2000 network.
To do so, you will need Venus OS version 3.71 or above.
Then go to Settings > Connectivity > VE.Can port (the one on which your chart-plotter is connected), enable the option called “NMEA2000-out”.
The motor RPM will be broadcasted with PGN 128002 (0x1F402) “Electric Drive Status (Rapid Update)” at a 500ms interval.
This will work only if your chart-plotter supports this specific PGN.
Regarding the Boat Page on the MFD app.
There isn’t a boat page inside the MFD app.
However, you should have the option to open the remote console from the MFD app to see it.
As a first step I suggest testing if your chart-plotter supports 128002 prior to diving into the more complex solution.
I do not have information on this.
However, there are already multiple ways to view the boat page on an external screen either locally or even remotely.
Could you try opening the remote console from the MFD app, it might already fit your need?
I decided to go a slightly different direction, which i think will meet my needs much better actually.
Instead of displaying motor data on my chartplotter, I decided to place an Android Tablet at my nav station as the “primary control center” for my boat, and then place my GX Touch 50 screen at my helm since I have room in my NavPod.
I picked up a Lenovo 10" Idea Tab today, and it synced right up following the directions. Super smooth!
Anyway, I played with the boat page a bit today. I really like it, but it seems like there should be more motor data on the Boat Page. The Boat Page has what I believe is battery temp (from my REC BMS), but does not have controller or motor temp (which is much more important to me).
Is there anyway to add it, or could it be a future enhancement?
Indeed you’re right, the only temperature shown is the battery temperature.
It’s coming up, the controller, motor and coolant temperatures will be shown (if available) on the boat page, it’s planned for the next major release (3.8x).
In the meantime those temperatures are visible under Settings > Devices > Your Controller.
I will update this thread once the changes are in beta.
