What device do you use to gather the engine data? I have a Yanmar 3JH4E on my sailboat and would love to record RPM mainly, but also temp and oil pressure, But I haven’t been able to find how to collect and record this data.
There are two integrations available in VenusOS to gather engine data:
- NMEA2000 (PGN 127490, 128002, 127488, 127489, 127493)
- CANopen (Sevcon gen4, Curtis E/SE and F controllers)
However, it’s unlikely that your engine will output NMEA2000 out of the box.
Alternatively, there is also the option to go down the Node-RED path where you are free to gather the data however you want and inject them into VenusOS as a virtual E-Drive.
Note that while technically possible to report data from an ICE, the boat page is designed and aimed at electric drives.
My diesel engine alternator is controlled by a Wakespeed WS500 so I can get engine rpm from that, plus the GPS gives me a few readings on the boat page so I do not have to go into devices to find the info. An Arco Zeus alternator controller would also do this.
Boat is in boatyard TAM having some work done, including connecting up Sevcon controller to Cerbo so boat page can display motor data.
Is there any way to select which parameter is the big one in the middle? It’s a canal narrowboat so would prefer power, rpm is next, speed is very much the lowest priority since it fluctuates a lot and also doesn’t really matter.
If this isn’t possible and it defaults to speed, please could this feature be added?
Hi Ian,
No, it is not currently possible.
If GPS speed is available, it will take priority over E-Drive power.
There is no plan to make it customizable at the moment.
It’s worth mentioning that starting with v3.80, the GPS speed is filtered to remove some of the noise.
This will help reduce the fluctuation you are seeing.
Could I request that it’s made selectable, this should be pretty simple? For an electric boat on the canals speed is of little or no interest, but power consumption (or rpm) is…
(I suppose I could unplug the GPS USB dongle from the Cerbo but this means crawling around and undoing an access cover – or can it be disabled from the remote console? Can’t try right now, boat is offline…)
BTW is there any idea when 3.80 will be released? My boatbuilder doesn’t install/support beta releases, for very good reasons… 
I agree that it should be selectable. I rely on RPM and current the most. I love the boat page and it’s working flawlessly, but I constantly have to squint to see RPM. I would love to be able to select RPM for be the large font/gauge in the middle.
Ok, feedback received and noted.
We cannot promise that this will be resolved, but if there is eventually an easy way to do this, we’ll share it.
To currently achieve what you are both describing, it is always possible to modify the UI files yourself, but it is a more hands-on approach, doesn’t survive updates and one where we cannot assist more than the public documentation available.
Thanks Nils – it should be easier than allowing user selection of the circular bar graph elements on the overview page, which you already do… 
I was talking to my boatbuilder (who has been rolling out the Boat page – all are hybrid boats for the UK canal market) this morning and he said most of his customers have exactly the same complaint as soon as they see the page…
