Hi folks!
This weekend I used a Raspberry Pico to grab some UART related protocol from a Votronic solar controller. I got some reading like charging current etc but also some status information, e.g. if the controller is in idle mode.
I send via UDP the information to my Signal K server on a Raspberry PI.
Long story short: The status information can't be sent as true and false, at least I didn't find it. So I added a path in Signal K and I added several items which get a ONE or ZERO, like the standby YES or NO.
But with the onboard dashboard app this can't be visualized. Of course, I could create a path for each value, so I could show at least ones and zeros, but I would rather like to show some LEDs on a dashboard, green and red or on and off.
Is this possible in Signal K? And if so, is there any documentation...
PS: One of the biggest hurdles of Signal K is the few information which is existing in the Internet. Just a few examples, I even couldn't find a full specification of possible meta data. The UDP is fairly easy but you try a lot if you can't find one example all the way trough.
Best regards, Malte
