Hi all - how do I...

End result - have an ESP8266, ACS1115 measuring battery voltage then sending the data over wifi to the Pi. 

So should be quite easy to get the data into node-red - but what about signalk? 

Better to have the ESP send a signalk string or just data and let node-red create the string? 

hopefully the esp will also serve a webpage so if the Pi is off the data can still be read from anywhere.

Any pointers very gratefully received, TIA.

Fantastic! Lots to learn in there, thanks.

@PaddyB: can you please elaborate on your battery voltage solution, maybe also with diagram and pictures.
? is ESP/ACS powered by? / ESP/ACS power consumption? always on or wakeup switch? Are you planing e.g. "remote inquiry" by op?

I am looking for a nice solution with op to check battery status from shore and yours seems very nice to me.

TIA for sharing

Will do, might take a while though, the todo list on the boat just seems to get bigger not smaller I've had something working already with node red sending a request to the esp8266 but think it would be better for the esp8266 to do it on it's own, creating a web but also sending data out over mqtt if there's wifi so it can be seen anywhere.
