Semi-automatic digital logbook for Signal K

[bergie]

For engine hours, you can have Signal K operate a counter: https://www.npmjs.com/package/signalk-hour-meter
You need some way for Signal K to know the engine is running. For example, RPMs. On our boat we use alternator output for this: https://www.npmjs.com/package/@meri-impe...-engine-on

Trip logs require something to output navigation.log. On my boat this is done by the paddle wheel sensor. GPS based method would also be doable, see https://github.com/meri-imperiumi/signal.../issues/62

For backup, you need to locate the .signalk directory. That is by default in the home folder of the system user that Signal K runs as, but may be also different in your setup.

BTW, if somebody wants to see how the mostly-automated logs look like, we publish ours as part of our blog posts. See for example yesterday’s sail on the Szczecin lagoon: https://lille-oe.de/2023-04-12/
