Good idea about a Node-red flows repository, on the to-do list is save a load of handy snippets to github, will post a link if the to-do list entries stop expanding quicker than getting ticked off
As for arduino/esp - mqtt sends data as a string (text) so you need to convert back to a number for signalk to be most useful. Might be better sending the data as signalk over UDP , means the data goes straight into signalk as numbers. Also I find it much better to just use the signalk node-red app, it has the signalk nodes ready to use.
