Lol.. yes split screen on ipad also works.. Is that ipad split screen you are showing or a new exciting feature?
I now have 2 tablets and 1 old phone all displaying simulated data from SKSim plugin.. V.cool.
Actually not as cool as I would like, Raspberry fan keeps turning on (set to 75). I would like to have AvNav data screen showing the signalK raspberry pi environmental stats ie: "environment.rpi.cpu.temperature". Is there a way to specify sk paths like this when using a widget like RedGauge_Temperature?

It's split screen within browser
Quote: Is there a way to specify sk paths like this when using a widget like RedGauge_Temperature?No problem. you can define any SK Path.Click on "Value" and choose your favourite path

The split screen is some sort of a preview - running 2 avnav instances in one browser window.
You can reach it with http:/xxxx:8080/viewer/viewer_split.html.
Will be a bit slower as it really runs everything 2 times. In the future this will be completely integrated.
For the SK stuff . yes you can display everything from vessels.self in AvNav.
Just use the layout editor - it will show all pathes from sk that currently have data in them (so you need to feed SK with data first
).If you miss some formatter or some nice settings for the gauges - this can easily be achieved with a few lines of js code.
For the pi CPU usage:
What else do you run on the pi?
AvNav itself should be low on CPU. If you use o-charts the ocharts plugin will use a complete CPU for some time as it pre-renders charts for faster display later on. But you have 4 CPUs (i.e. 4 kernels) - so also at most around 25% of the whole system.
But if you run the OP desktop stuff (or even a VNC server) - this really consumes CPU and memory.

Hi Wellenvogel
At home I use the pi as a wifi access point and I generally have vnc running on it - From your comments above that would probably explain why its getting warm.
I now have a AVNav data panel set up to display Raspberry Pi temperature/memory/SD utilisation, thanks for all your help
I really am blown away by how good AvNav is.
Out of curiosity I would like to have a master AVNav device on the boat and then use that to control what the other devices display. The remote function gets me part of the way there as long as the remote devices display exactly whats on the master device. Ideally I would have each device on a different remote channel, use the master device to control what is displayed on that remote channel and then disconnect the master device from controlling that channel, so the two devices can display different screens. If/When I currently try to disconnect the remote channel the remote device follows my control to the disconnect screen rather than the remote device staying on the screen i want it too. Is there a way for me to do this?

But it's a good point.
Would you maybe like to open a GitHub issue to address this?

Happily submitted Github issue, thanks for considering.
For my next project, can anyone recommend a cheap and cheerful External Wifi Camera that easily works with RaspPi and AVNav? Key criteria would be minimal lag so that I can use it for coming alongside pontoon as well as seeing the telltales on genoa.. Ideally USB powered so I can plug it into portable battery and learn which location makes most sense..
I'm hoping the camera part is easy as I think the fun will be nicely configuring/interfacing it with AVNav?
RE: AvNav implementation in OP2 - wellenvogel - 2022-02-23
For AvNav there is most probably no real integration - but if you have a web page that can display the cam stream you can add this as a user app to AvNav.
You can even create your own HTML page around a video element...
AvNav implementation in OP2 - new version - wellenvogel - 2022-03-01
A new Version of AvNav is available.
It has a couple of improvements and corrections - refer to the release doc.
One of the major features is the adaption to the new o-charts shop.
Additionally it has been simplified to share o-charts charts between AvNav and OpenCPN.

Any news about openplotter-avnav-installer app for bullseye?
