Anyone sending Signal-k from Arduino?

[ddelorme]

I just started to get a ardunio nano set up as a mast head unit running. I use a NRF24l01+ on the ardunio to send wind speed and it will turn the anchorli on and off via a Mosfet. The rpi openplotter has a switch wired into GPIO25 that sends message to mast to turn on/off anchor light. The Pi /openplotter  receives sensor data and sends this to siglnalK ie environment.wind.speedApparent.

here is the code i use to send data from pi to SignalK

Code:

import socket
   sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
   SignalK = '{"updates": [{"source": {"type": "wind","src" : "arduino"},"values":['
   SignalK += '{"path": "environment.wind.speedApparent","value":'+str(aws)+'}'
    SignalK += '{"path":.....add more here 

    SignalK += ']}]}\n'
   sock.sendto(SignalK, ('localhost', 55559))
   sock.close()

 
It works and i am just sending the minimal data via the nrf24. Much lower power then WiFi. I now just have to send 12 dc up the mask to power unit. It appearers to use about .220a/hr when Anchor light is on.

I think a mesh network of low power sensors run on batteries could clean up the system. "Sensor pucks" Eh! they take a lickin and keep on tickin..

I would like a SignalK Display modules ie 3"/3" that could read the stream and display selected data wired or wireless and sunlight readable.
