So far - most of it working but need a bit tidying up-
Esp has esyeasy loaded onto it >

Then all the setting up is done on a web page, not as versatile as writing stright code but much easier
There are 2 ADS1115, a voltage divider, BMP280 and a so far unconnected serial /TTL .
On the initial setup you connect the esp to the openplotter network then it connects to that automatically and has a 10.10.10.*** IP address. Everything goes out as MQTT, then some of it gets converted to signalk by openplotter and some other data is taken care of by node-red.
Such a powerful little board for so little money!
The control(IDX) indicates where the data is sent to, MQTT is 1, UDP is also an option. Seems stable enough though occasionally it seems to restart itself - only noticed if you look for how many long it has been running on the main tab, 3 days 23 hours it says at the moment. Only one serial connection unfortunately, but better than none
