influxdb plugin - first attempts
Is that a DNS problem? I'm not sure what tools I have to be able to diagnose DNS issues (on a Victron Ekrano) but maybe I'll try just the IP instead

influxdb plugin - first attempts
Oops, I'd missed the NPM help. It seems most of the parameters don't need setting at all.
I generated a new API token and put that in, and it seems better - except that the error has changed to
Aug 23 02:17:23 WARN: Write to InfluxDB failed (attempt: 1). Error: getaddrinfo EAI_AGAIN <myhost>.com at GetAddrInfoReqWrap.onlookup [as oncomplete] (node:dns:107:26) { errno: -3001, code: 'EAI_AGAIN', syscall: 'getaddrinfo', hostname: '<myhost>.com' }

B&G Performance plugin
Ahhhh - is this what the 'derived-data' plugin does? Just noticed that.
I see calcs/trueWind.js in there, and while it doesn't know about mast rotation angle (not surprising seeing as N2K didn't implement a PGN for it) perhaps I just need to add a modified version of that code that includes my "rudder angle" (or "trim tabs" or whatever PGN I use for the rotation sensor)... Maybe this is the right direction?

B&G Performance plugin
@Teppo Kurki sorry, I should have said that I'd looked at the plugin, but had trouble deciphering it. The readme really boils down to the first line "Generates B&G performance PGNs to be displayed on a Zeus" but if the source code is all in index.js, it looks like this is a mapper that takes SignalK paths and assembles a special PGN with key-value pairs. It doesn't actually do any of the calculations itself I think?
I hadn't realised that @HansT might be in here as well! Hans, if I have understood the purpose of your plugin correctly, may I ask how you generate (for instance) TWS from AWS, COG (or heading) and SOG (or speed)?
Am I correct in thinking that you are trying to replicate the functionality of the H5000? Maybe this plugin is just one part of the system and I just haven't gotten familiar with things yet?
