raspberry pi zero KIP external display - Screenshot - 2019-10-05

Hi everyone, I'm using a raspberry pi 3 for opencpn, and I recently discovered the KIP functionality in signalK. I had planned to use a raspberry pi zero W paired with an E-ink screen to display basic (speed and/or depth...) information outside the boat. Unfortunately (but unsurprisingly) the pi zero isn't powerful enough to load the website. 

Is there a way to access the signalK data stream? /  if so how is it organized? (my knowledge in network stuff is pretty limited) 

Thanks !

you could display kip on a smart phone or tablet.

I too looked at displaying some info on an E-ink display and I know that it can be done but perhaps not the website but instead the data. I purchased a device from seandepagnier@gmail.com of pypilot https://pypilot.org/store/index.php?rt=product/product&path=73&product_id=126

Works well with a davis anemometer

Measures wind speed and direction as well as barometric pressure. Compatible with pypilot for wind-steering modes, and opencpn for display and data logging.


Other than that you can go headless to a phone or tablet as stated earlier.

Good luck on your project.

I'm using a bright LED matrix, see this post: http://forum.openmarine.net/showthread.php?tid=1390&highlight=matrix
The built-in Node-Red (Signal K server) sends MQTT to again Node-Red (Raspberry Zero W). I published the two used Node-RED flows: 1. on OpenPlotter RPi and 2. on RPi Zero with LED matrix plugged on top.
