Wind Sensors

Issues with ESP32
Ya the dead zone was a pain to deal with it came down to my ref voltage not being fused in.
I had to remap the voltage to fix issues with the voltage curve then Float remap to deg. My dead zone is 350 to 0 deg. 
Power... well it is currently at about 240 millAMPS @12V Spec max 5. amps @ 5v. Part of that is the draw from the device used to read it.  so it is about 160 milliamps best guess. This could be

Did you measure 160 milliamps at 12 volts?   This is a lot more than a raspberry pi zero.

reduced in the future when the code matures in regards to sleep functions.
Lag is not noticeable i am sending data to RPI WIFI no wires. But more testing is required. I don't drop the connection once it is set hence issue with sleep.

Wifi is not reliable for realtime data, and will have a much higher latency and this latency can change all the time.

People still use stainless steel rigging wire even with crevice corrosion I have seen several de masted, and they replace again with stainless steel when galvanized and spectra are both better.  So you can use wifi for wind sensors but I doubt I will.

It may work well in your one test case, but depending on what else it is doing, what else is going on wifi other networks around, or forms of radio interference, and also many other devices have much less reliable wifi than the pi.

I can use quadplex wire, so there are 4 wires in 1 instead of 2 in 1, so not much difference running the wires since you still need power.

 I am redoing my PCB since I am new with Kicad and pooched a few things.
Can Pypilot read the Sk wind keys or do i have to stick to NMEA?

Currently does not get wind that way, but it's possible to do it.  What would be the advantage pver NMEA?  Is there additional data for wind?

I ask because i am thinking of a rewrite to Sigksens as a sensor.
I am looking at the board and I am wondering about adding a BMP280, It might not work well in a air/water sealed box. Also a second mosfet to control a Motoring Light?

This light is technically supposed to be halfway up the mast.

I am using a 4" round plastic ip67 electrical box with the anchor light fixed to the lid. It fits my masthead. I need to decided about the connectors though the box. I need 1 2pin for 12v and 1 4pin for the Davis. Ideas?

I am heading out to the boat today to get my autopilot so I can test the Pypilot Motor controller.
I just received a Nextion display, I am thinking it might be a good client for Pypilot.
