My Testing Setup - Help!

[ALULAsails]

Hello OpenMarine community, 

Let me begin by thanking all of those who have contributed to this project. OpenPLotter, SignalK, etc. I am blown away. Absolutely brilliant. 

I am a passionate Canadian Sailor currently stranded away from his Kelly Peterson 46 sailboat which is currently in New Zealand. I am not a software developer, but I have been having a lot of fun creating what will become the backbone of my system when we get to go cruising again. If anyone wants the schematic I have created, I'll gladly send it to you. Basically a NMEA 2000 system with an outside mounted B&G Chartplotter and a XB-8000 Vesper AIS which will convert the NMEA string to ingest in the Raspberry Pi. I will then mount a 13" portable screen at the chart table and it will not only be able to display all of the "marine" NMEA data but also temperature, pressure, rel humidity and some additional temp sensors. The idea is to have all data both at helm outside and inside at Chartplotter. Right now I only have some old school electronics outside with no repeater or anything.

I took a video of my testing setup installed on top of my fridge. I have connected a BMV-712 to the Raspberry Pi, 3 temp sensors, the BME 280 and using SignalK and the Kip plugin for visualization on the 13" portable screen. Lots of fun! 

HERE IS THE VIDEO

I have also run into a few minor problems I was hoping perhaps someone can help with:

• My Raspberry Pi keeps on blanking the screen even after I have disabled the ScreenSaver. I will follow some threads I have found online so hopefully can solve this
  
  
  
• My initial testing saw me with a BMP180 temp and pressure sensor. I used Python code to retrieve the data once every 60 sec and I was putting that into an InfluxDB. It worked perfectly and I never dropped the "connection". SignalK does not support the BMP180 sensor so I installed the BME280 sensor instead. SignalK does read it and it all works well for a few hours. I use the SignalK->InfluxDB plugin. But overnight, with no activity on the Pi, it drops the connection. I can see it on the Grafana dashboard the next day. Any idea why this would happen? Only way to fix is to reboot the Pi.
  
  
• Overnight I also dropped the BMV-12 connection. Only way to fix is to reboot the Pi.
  
  
  
• The Kip Dashboard plugin is great but I am having a few issues with it. I can't get the historical data widget working. That's sort of OK as I would prefer instead to embed a Grafana dashboard into a widget. On my video that is the broken widget you see bottom right. I don't understand the Cross Domain Security Rules and how to fix that on the Raspberry Pi. Does anyone know how?
  

I think that summarizes the few little roadblocks I have left to solve. Thanks in advance for all of your help!
