influxdb plugin - first attempts
I've setup an influxdb and have both a password and an API token - the API token seems to work fine when using the influx CLI. However, the plugin requires quite a number of parameters to be set, and none of them have defaults, so I'm not sure which are the critical ones (and I've no idea what to use for most of them).
In my server logs, I get the following message:
Aug 23 02:08:03 TypeError: Cannot read properties of undefined (reading 'filter') at Object.json (/data/conf/signalk/node_modules/signalk-to-influxdb2/dist/HistoryAPI.js:383:45) at /data/conf/signalk/node_modules/signalk-to-influxdb2/dist/HistoryAPI.js:166:13 at process.processTicksAndRejections (node:internal/process/task_queues:95:5)
Would anyone have any tips on what this might mean?
Thanks!
greg

B&G Performance plugin
Hi there!
I'm new to SignalK so please be gentle 😉 I have a B&G Zeus chart plotter and a fairly standard wind sensor (B&G WS310) which generates AWA and AWD. However, I also have a rotating mast... I am measuring my mast rotation angle using a Honeywell magnetic position sensor and the YachtDevices YDRA (A/D converter that generates either the Rudder Angle PGN or a Trim Tab PGN - I'm using Rudder Angle). I was excited to see the B&G Performance Plugin, but I don't really understand what it does... It appears to generate the custom B&G PGN 0x1FF08 (130824) that handles multiple key-value pairs to handle parameters that are not explicit PGNs themselves. The B&G key-value data PGN includes a field for mast rotation (key 156). However, I cannot tell if this plugin emulates an H5000 processor and actually calculates the corrected AWA/AWS/TWS/TWA/TWD itself, or is only a formatter for sending the data to an H5000 for processing? If the plugin does the mast rotaton processing, then I'm delighted. If it doesn't, then I will use the YDNB (which can act as a little N2K processor itself) to do the calculation. Can anyone help me understand the purpose and functionality of the Performance plugin? Sorry for being long-winded! Cheers, greg
