Android/Node-red for boat monitoring

This might be of interest to a few out there, node rd available on android!

From last nights onboard playtime..

Briefly ...
Extremely accurate little 4 channel volt meter electronics board is attached to the batteries, ads1115.
It talks to a little esp8266 microprocessor which has wifi.
An android tablet is running an app called Termux which is basically Linux, this is running a sort of graphical programming language called node-red.
Node-RED says hello to the esp8266 over wifi once a second or whenever you want and when the esp gets this it sends back the voltage which node red stores in a file on the tablet with the time.
YAY!


Should work fine on a mobiles phone as well, if online then node red is really powerful, add some thermometers if it gets too cold send an email, tweet once an hour with anything interesting.



Node red is free on the web for a play around, Google node red Fred.

Also easy to create a dashboard for any device onboard on the same network to view as a webpage.


Nore-red is programmed as a webpage so can be done on a laptop instead of fiddling on a phone. Loads a cheap senors available to attach to an Esp8266 - cheap waterproof thermometers, amps, movement sensors. Also should be easy to trigger relays etc from anywhere over the net.

Certainly not something for the electronically fearful but not that hard really and extremely powerful for so little money.
